# Win-GHG GUI - Change Log 9.0.0 (2026-10-07) ================== Fix bug sending cloud commands to SF. Add code to parse and display licor_provision_result response from SF Errors from provision request will appear in the SmartFlux and Diagnostics and be shown as a detected issue in the SmartFlux Status 8.9.11 (2026-09-23) =================== Fix seg faults when sending smartflux commands through status server on diagnostics form Smart flux commands now sent status server timer only though the status form Commands to provision or enable/disable cloud will be sent on status timers in diagnostics form or status form depending on which one is running 8.9.10 (2026-09-11) =================== Diagnostics waveform data is now manually turned on Display last upload to cloud tds in instrument's time zone Fix provision cloud buttons being disabled Refactor sending cloud commands to status server 8.9.9 (2026-09-02) ================== Refactor sending commands to SF in diagnostics form. Implemented as a dry run for testing. 8.9.8 (2026-03-31) ================== Update SF panel cloud provision fields from status and diagnostics forms already communicating and parsing status server output. 8.9.7 (2026-08-25) ================== Release Candidate that adds LI-COR Cloud provisioning and enabling cloud data uploads. GUI Changes since 8.9.4: - Latest LI-COR Cloud status details now availble under Diagnostics. - SmartFlux options now display and control cloud provisioning and enabling uploads. LI-COR Cloud status info being displayed in Diagnostics, now contains last upload time and date and whether that upload was sucessful or not. If not, the cloud error is included in a popup dialog that the user can click. In SmartFlux options, message dialogs will now popup when viewing if there are communication errors between Win-GHG and the SmartFlux status server. 8.9.5/8.9.6 (2026-08-19) ======================== Internal releases for testing and bugfixes displaying cloud info from the status server. 8.9.4 (2026-08-17) ================== Add support for LI-COR Cloud provisioning and enabling cloud data sync App now displays Cloud status and new provision/enable Cloud controls. 8.9.3 (2026-07-07) ================== Bugfix for testing SmartFlux firmware versions less than 2.2.53 that don't have status servers to display in GUI Updated Downloader password for licor user 8.9.2: ============== Added leading 0 to sub-zero parameters in RS-232 output combo box. Was not able to change the sort order due to unforseen coupling issue with embedded ghg. Version 8.9.1: ============== Addressed EC Issue 644: Removed the settings in the connect screen for RS-232: 5.0 10.0 20.0 Added warning to RS-232 Screen on Outputs section. Added logic to not display the sonic file inconsistency check. This addresses EC Issue 635. Added check to highlight incompatible logging configuration (Continueous above 2Hz) and procedural steps outlining how to resolve it. Added logic to display error dialog only once when path is blocked or loose cable is detected. Otherwise, would display new dialog once per second. Removed check for sonic file name consistency due to user complaints. See EC Issue 635. Version 8.9.0: ============== Revised compatibility checks to relax backward compatiblity constraints. Updated help files and revised version number for release. Version 8.8.49: ============== Added updated help files Version 8.8.48: ============== Renamed Syatem Status to SmartFlux Status on the main page. Added Status server support for SF2/3 MAC address. Now, if SF2/3 is behind a modem, the status server will provide the MAC address, and win-ghg will fill it in accordingly. Version 8.8.47: ============== Corrected flaw in autodownloader in which the scheduled download would not pull the files. Version 8.8.46: ============== autodownloader 2.1.0: (2021-04-21): Removed "Verify Connection Button" from Instruments Pane Added "Retrieve USB Info" button to USB Info pane Disabled automatic USB info retrieval when launched with command line parameters All panes are now active at startup Updated state messages Aded sonic file name display to diagnostics when sonic file is flagged as bad Added the date of the file if it is flagged as > 33 minutes between files. Added logic to confirm that SiteSetup/SonicAnemometer/Height value is greater than zero. Added warning triangle to diagnostics page for USB drive when not mounted. Version 8.8.45: ============== Addressed issue of false positive readings on the main page caused buy not filtering out the cp2_raw_data_folder content check when the system is not a DS system. All instruments provided for testing, read correctly now. Addressed issue with file split behaviour also giving a false error for the correct setting. Addressed issue with autodownloac app not reseting ICOS file count value when the connection was refreshed (2.0.8). Version 8.8.44: ============== Added comprehensive logic to disable diagnostics/smartflux and diagnostics/advanced tabs when not connected via ethernet. Version 8.8.43: ============== Added additional call in the connect section to handle URL resolution Moving from gethostbyname to getaddrinfo, unintentionally disabled URL resolution. This has been addressed, and is now working once more. Added ICOS count to upper right panel of autodownload program (2.0.7) Addressed inconsistent connection mechanism when double clicking on an instrument vs pressing the connect button on the connect dialog. Added a simple filter on the main form to hold the final status indicator at "Assessing..." until all of the elements have been processed. Adjusted connect dialog: - Replaced "Use LI-7550 IP Address..." with "Modem Connection (Smartflux2 only):" - Replaced "NF" with "DIRECT" in IP History line - Replaced "F" with "MODEM" Removed "Continuous" file split option on USB log rate of 5Hz and above. Version 8.8.42: ============== Added back missing version compatibility balls on the initial connect screen. Modified the IP history section of the connect screen eliminating the select button in favor of simply having the combo box automatically populate the fields when the item is selected Corrected issue when the app disconnects that it also exits the connnect screen Adjusted layout of connect screen to (hopefully) reduce confusion in new connection methodology Permanently enabled the "Reboot" button on the Settings/Network dialog to allow a machine to be rebooted anytime regardless of logging state Adjusted the file split combobox to only allow 30 minute file splits if logging at 5 Hz or greater. Added some minor connection logic to handle an edge case in which an instrument behind a modem may report a different ip address than the forward facing one used to connect to it. Strange on the inside but not uncommon apparently. After further investigation and testing, found it necessary to add a separate port field for the Smartflux Status server, and also a checkbox indicating whether the app should assume that the SF23 has been port forwarded or not. Version 8.8.41: ============== Refactored the status_server socket connections to use a single socket between the main form and the diagnostics form, and to maintain the connection once established rather than re-establishing the connection each time through the timed loop. It should stabilize the connection between the win-ghg app and the SF2/3 unit and make the app more responsive. Revised the downloader app (2.0.6): ============== Expanded the destination box configured winscp to target the destination directory when launched added ICOS checkbox selection to the scheduled download option Version 8.8.40: ============== Migrated buttons off of the Diagnostics/Smartflux tab onto a new tab labeled "advanced" Added two new buttons: Erase onboard data, and format USB drive. Implemented new modal dialog for the factory reset, adding a timed wait period of 15 seconds before the proceed button is enabled, and also added a blinking message indicating the severity of the action. Updated the downloader app, spliting the lower panel into two with an immediate work flow and a scheduled workflow. Version 8.8.39: ============== Implemented some removal logic on the diagnostics page to hide info on the FluxSuite and Data Repository sections if one or the other is disabled. Revised the downloader app (2.0.4 now) to address excessive information retrieval times. Addressed missing compabitility colored balls on connect page Version 8.8.38: ============== Adjusted formatting on diagnostics page Version 8.8.37: ============== Adjusted layout of connect screen to address minor shortcoming overlap Added a feature where setting USB output to 20Hz automatically sets the BandWidth to 10. Setting USB output to 10 Hz automatically sets the Bandwidth to 5. All other output settings will have no effect. Added a reboot command and a factory reset command to the SF23 status server. Both are accessed via buttons on the Smartflux tab of the diagnostics page. Hid the reboot SF button from the Smartflux dialog. If the node-windmill interface is frozen, it would not work anyway. Putting it in the status server means that it will always work. Migrated a digest version of the contents of the SF23 Diagnostics page to the main page. This will have the following impacts: - While on the main page, the status server will be contacted every 15 seconds - When transitioning from the main page to the diagnostics, the main page timer will be suspended until the diagnostics page is closed. As such, it can take up to 15 seconds to redisplay the message on the main page. - If anything at all is amiss, it will show that there are issues and recommend the user check the system diagnostics page. This level of granularity was requested by the Science and Support staff. Added a small mechanism to store up to 5 additional IP addresses on the connect screen. The controls are extremely basic and should not be difficult to under- stand Reworked the downloader app to use winscp vs its own internal mechanism. While attempting to revise for the new file structure, it was learned that the program had an inherent flaw. As such, it would fail after 750 - 850 downloads. This posed an unacceptable outcome. To that end, the downloader app has been reworked to call winscp for the file transfer. Version 8.8.36: ============== Minor adsjustment on the 2nd Y-Axis. Had to disable it when it is picked from the front panel, but enable it when picked from the chart dialog. Fortunately, it was a one-liner change. Beyond that, had to adjust the layout a bit. Re-addressed issue 217 putting back the second Y axis component. Fortunately, I'd only hidden it vs deleted it. Whew! Addressed issue 534 in which the integration functionality had been disabled. It appeated that this was an update started by Michael V. that was left unfinished when he departed. Added checking code for the diagnostics tab to look up an sf3 by IP address rather than name. Ran into one instrument that was displaying 2 names (1 by hostname and a different one by mdns. This caused things to break. Corrected by bypassing the name look up when an sf3 is involved. Added model checks for CR1000 and CR3000 to code to correctly identify a CSI logger. Undid the "Last Run" clickable link. It neve worked remotely, and is now supercedeeeed by the log file transfer on the diagnostics page Addressed Project EC Issue #80: Enhancing PC Logging from win-ghg Added capability for win-ghg to communicate with smartflux23 version 2.2.50 or higher via a socket call on port 5050. Use the resulting status information to provide enhanced feedback on the state of various things including: EddyPro FluxSuite Access Clock Settings Sonic Data Collection Version 8.8.35: ============== Addressed EC Issue #217, removal of second-Y axis configuration from the chart control Added mdns lookup of smartflux mac address and display it on smartflux tab when a smartflux is connected. Adjusted label on diagnostics panel to read "GHG Embedded" vs "Smartflux3" embedded to address customer confusion Added IPv6 support such that a customer may enter an ipV6 address and the application will use it to connect to the instrument rather than going through Bondjour. Also flowed the changes through to the autodownloader. It will now support IPv6. Version 8.8.34: ============== Adjusted biomet page and broke apart the conjoined DAqM/Sutron instrument list into two separate lists by adding a separate DaqM selector radio button Augmented instrument name field to restrict it to Alphanumeric (i.e., A-Z, a-z, 0-9) along with '-', and '.' only. This addresses project EC issue #44 Augmented error message on parse errors. Now asks user to confirm that they are using compabible software versions between windows and embedded. Version 8.8.33: ============== Corrected the biomet page to correctly set the DAqM/Sutron and CSI biomet radio buttons depending on what is connected. If nothing is connected, it will default to a DAqM setting. Corrected Calibration page such that it displays the correct zero page content when the dialog is initially opened. Corrected Calibration page such that it will now only accept valid floating point values in any of the manual calibration fields. Added logic to remove whitespace from the sonic serial number and sonic software version fields to keep embedded ghg from disconnecting Version 8.8.32: (2019-06-14): ============== Added code to consistently set the winter/summer setting regardless of whether a DS or RS instrument is attached. Version 8.8.31: (2019-05-02) ============== Removed USB size display from Smartflux tab when instrumetn is a DS Version 8.8.30: (2019-04-17): ============== Adjusted the windrose chart to more accurately reflect a windrose and also to be more consistent with what FluxSuite displays Version 8.8.29: (2019-04-03): ============== Adjusted process on retrieving biomet ip address in conjunction with embedded ghg adjustment to pass serial number and software version for daqm units through to win-ghg Version 8.8.28: (2019-03-18): ============== Minor label change on Biomet Instrument selection page Version 8.8.27: (2019-02-01): ============== Addressed issue raised by Jiahong Li in which it appeared that the analog settings on an LI-7550 were not being committed if it was sent from the SiteSetup/Sonic Anemometer/Analog Input Settings path. Conversely the settings would stick if they were sent from the Analyzer/Inputs path. After investigating, it turned out that the first one called the Show() method to display the form while the second called the ShowForm() method. The ShowForm() method caused the page to be refreshed with the instrument parameters, while the Show() method did not. Consequently, the first path, gave the impression of not committing the settings when, in fact, the settings were being committed, but not displayed. Both paths now call the ShowForm() method. Version 8.8.26: (2019-01-29): ============== Revised sonic selection section to align metek metadata sonic names with those currently being used in eddypro (version: 7.0.0) Version 8.8.25: (2019-01-25) ============== Revised the Downloader application (now version 2.0.1) to retrieve daqm and image files from a host machine. This necessitated an expansion of the discovery mechanism to include Smartflux2 devices directly as daqm and image files are only ever stored on an SF2 or SF3 device. The downloader program will work seemlessly between an embedded 7550, an SF2 or an SF3 device. The behavior is precisely the same as it was, with the new capabilites of downloading the daqm zip files (both regular and backup) and image files with a jpg or png extension stored on the SF2 or SF3 devices Version 8.8.24: (2019-01-16) ============== Altered blueprint-utility launch button to utilize environment variable to locate the blueprint-utility executable. If the environment varialble is not set, that indicates that blueprint is not installed, and the button will not appear. If it is set, then the button will appear and be able to launch the app. Version 8.8.23: (2019-01-16) ============== Added more interim calls to the embedded system to attempt to make win-ghg more responsive. Adde a launch Blueprint Utility button. It will launch the blueprint utility with the corresponding ip address if the instrument is attached, and will launch it without it, if it is not attached. Version 8.8.22: ============== Cross connected the LI-7700 connect/disconnect buttons to the Site-Setup CH4 tab. The issue is that when the LI-7700 is either added or removed, if the user fails to go to the site-setup CH4 tab and press the apply button, then the contents of the co2app.conf file are left in an indeterminant state. The CH4 head item will be set correctly, but the model and manufacturer items will not be. This is addressed when the user presses the apply button on the set-setup CH4 tab which then populates these items correctly. Revised phenocam tab on SmartFlux dialog to support a second phenocam Partially reverted a recent change applied to the xnode section. Pulled the notifyListeners routine out of the value change check as it had the unforseen side-effect of suppressing needed clearing notices on the biomet data page, and thus causing the table to exhibit an "appending" issue. Data continues to be appended to the table rather than refreshed to it. The secondary adjustment appears to have addressed this. Version 8.8.21: ============== Revised lable on Radio button on Biomet section to include DAqM when selecting a sutron logger. Now it is a Data Acquisition System (DAqM) and Suton Logger Version 8.8.20: ============== Re-enabled both RM Young and Metek Digital Sonic Selection Augmented xnode parser with additional checks to ensure that when a node is written to (ie., updated) that it only notifies it constituent listeners if it's value has actually changed. If it is updated with the same value that it already has, nothing will happen. This change was in response to an issue raised by the support team in which it could be shown that a sonic selection would spontaneously change. The issue was traced to an onChange event that was being triggered even though the updated value was the same as the previous one. Unfortunately, this had a cascade effect of resetting a subordinate combo box'es index value even though the parent box had not actually changed it's value. This augmented code addresses the problem and will only trigger a change when it's new value is actually different than the previous value Added 3rd radio button on Sonic select form to allow a user to shut off the digital sonic when connected to an SF2 and LI-7550 Combo. When connected to an SF3, the Analog radio button simply disappears. Addressed state change issue in which a port is initialized to 0 in the analog case which throws the LI-7550 embedded parser off. Now it is initialized to 1 Addressed issue in which main status screen would be removed when the app lost connection with the instrument, but it would not be restored if the app was able to reconnect with the instrument on its own. Now, it will recover the main status screen if the app is able to reconnect with the instrument on it's own. Version 8.8.19 ============== Removed the option to select RM Young Digital Sonics until such time as the Marketing/Scientific group is confident that they've been sufficiently tested Version 8.8.18 ============== Removed the option to select metek sonics, until such time as EddyPro will will be updated to support it. Version 8.8.17 Added support for RM Young 81000RE Sonic in digital connection Version 8.8.16 ============== Revised connection check to ensure that app would not flag embedded 8.8.x as being incompatible Version 8.8.15 ============== Added support for RM Young V, RM Young VRE, Gill HS-100, Metek uSonic3 Class A MP Metek uSonic3 Cage MP, and Gill R3-50 sonics on digital channels Addressed shortcoming in software where whitespace in either the sonic serial number or software version is not accepted by the embedded application. Whitespace is now stripped out Adjusted front display to eliminate the sonic line vanishing on a smartflux connection error Adjusted smartflux connection error to be less spurious. Now should be a bit more stable Version 8.8.14 ============== 2018-03-29 ========== Removed zip checkbox from USB logging dialog. Now it will zip alway unless continuous logging mode is selected for the split interval. Then it will not zip. 2018-03-13 ========== Revised main.cpp and adjusted text title to accomplish the following: a. If connected to a "DS" title will be 7500DS b. If connected to a 7500 title will be 7500A/RS c. If connected to a 7200 title will be 7200/RS 2018-03-01 ========== Revised form tools to provide a appCalDir() vs appDataDir() when looking at calibration files. 2018-02-28 ========== Revised Site-Setup dialog to repurpose the analog sonic radio button to become a "No Anemometer Attached" radio button when a DS system is detected. This allows the user to deselect a sonic altogether from a DS system. As such, the config.json file will be set to "none" when this option is selected. 2018-02-26 ========== Added code to address a shortcoming in this implementation, in which the usb_state_change routine overrides the container settings in ch4_head_change. It is clear that Michael had intended the ch4_head_change routine to take prescendence, however, the usb_state_change_routine gets called every time the metadata dialog tabs are opened, and thus the ch4_head_change will always be overridden. The following code, addresses that issue. It should be noted that the state change is not picked up unless the site-setup dialog is actually opened from a closed state. As such, it was necessary to add a method in the main form to automatically close and reopne the site-setup dialog if it is already opened. This will cause the check routine to run and the corresponding state change to be picked up. *********************************************************************** Version 8.8.13 ============== Corrected disabled custom file upload field. Should be enabled when the CSV check box is selected. Now, it is. Version 8.8.12 ============== Added "OK (##)" for Signal strenght on diagnostic page Added "coming soon" for selection of Metek and RM Young sonics on Site Setup page Made Test point page re-appear though additional work will be needed on the embedded side to make it viable Will make the configuration page disappear Added DSI Number/Name to main status page when connected to DSI. Also Added Head Serial number to DSI Connection page RT Chart setting will now "stick" and be remembered the next time the app launches All modal windows will return to normal state if minimized and the main form button that created them is pressed again. 7x00 button now updates sub-menu correctly when swithing between DS to RS instruments. Corrected disconnect when verbose mode is deselected. Added 3 second delay to ensure ethernet synchronization Addressed calibration page displaying signal strength on zero tab at initial start up Corrected handling of model number. SF3 now appears as model SF3 Revised help files and added a DS specific help file Test points tab on the Diagnostics dialog will only appear if an RS machine is attached. It will not appear if a DS machine is attached. Title of Settings dialog was revised from "Status" to "Settings" MAC address was not initially being populated on the settings/network tab when connected to an SF3 Traced it to an embedded issue. Added close button to DS connect dialog Version 8.8.11 ============== Partially decoupled Sonic Anemometer connection failure from Smartflux connection failure. In 8.8.10, if the sonic connection fails, then a smartflux connection failure is also displayed. The issue was traced to the "connection" parameter which changes to false when the anemometer fails It is not clear if this is intended behavior or not. Regardless, that parameter is also used to check Smartflux connectivity, for which it registers a failure erroneously. The parse tree which maintains this state information appears not to maintain it in relative real-time. Rather, it maintains the last known state. As such, it will register a comm failure if the SF unit is down when the GHG system boots up, but will show that the SF unit is alive even if it fails after boot up. The partial decoupling comes from checking the model number associated with the SF unit. This parameter is retrieved from the unit after a successful connection to it. As such, if the Anemometer fails, and the model is not empty, one can surmise that the SF unit was communicating at one point and likely still is. It is not ideal, but it is what we have. Altered the sonic connection state displayed on the main page to display current state during the connection process, and display the configuration only after a successful connection. Turned the last run label field into a clickable link that will allow the user to download the output file of the last run, if the instrument (SmartFlux) has an IPv4 address. If it has an IPv6 address, the link is disabled. Renabled the editable hostname field under settings/network. Now the user is able to change the name of the SF3 instrument if so desired. Added a serial number label field to the SmartFlux dialog. Users can change the name on an SF3 but they cannot change the serial number. Version 8.8.10 ============== Added a check in the Biomet dialog that will eliminate the spurious error message indicating that the user should select a 9120 from the list when that has already been done. Adjusted the Data repository dialog per Kevin E's direction to turn the ICOS CSV option into a checkbox vs radio button and to make all of the checkboxes a simple OR relationship rather than an Exclusive OR between the top three and the ICOS CSV. Had some difficulty getting the properties right and had to duplicate an existing control and simply rename it to ICOS CSV to make it all work. It does now. Version 8.8.9 ============= Adjusted the calibration dialog behavior to disable the CO2/H2O Span value text boxes from updating their values after a span or span 2 operation has been initiated. Now, the boxes will simply retain the value that the user entered before pressing the span button. Version 8.8.8 ============= 2017-09-06 After the recent loss of Michael Velgersdyk, Douglas Allyn was tasked with reviewing the code-base for the GHG Windows application (version 8.8.7 and addressing the following issues: a. Layout of dialogs and ribbon buttons to support display setting of 100% and 125% -- 8.8.7 has dialogs that become unusable at 125% due to the scrolling controls being cut off on the right side of the dialog b. Recover History tab on the Calibration sub-dialog: -- 8.8.7 hid the history tab as Michael had planned to address it after his return from China. Unfortunately, he didn't complete that work. 8.8.8: ====== 100% vs 125% settings: ---------------------- The majority of dialogs affected by the display setting are tabbed dialogs implemented on a single form. This form has a default width setting which is extra wide in order to accomodate the largest dialog. Michael would then, size it down depending on which other dialog was being displayed. The problem was that his sizing down was done on the 100% setting, and would make the dialogs too small on the 125% setting. Douglas simply removed the size down operation and allowed the dialogs to remain extra wide. They do not look as nice, but they will work at any display size setting. History Tab: ------------ Michael had hidden the history tab if a DS instrument was attached. Douglas simply removed that constraint. Michael also disabled the form reload/refresh for that tab if a DS instrument was attached. Douglas removed that constraint also, and everything appeared to function normally. DSP Version: ------------ When a DS is attached, the DSP Version is not correctly populated. At the request of the support team, that field is not displayed at all when a DS instrument is attached.
