I have a Facet that’s running RTK firmware version 4.1. I updated the ZED-F9P firmware, using u-center, from 1.32 to 1.51. After the update, the Facet was working okay except SW Maps in its GNSS Status screen was showing “N/A” for the estimated errors and accuracies.
I looked through .ubx log files from the Facet from both before and after the ZED-F9P firmware update. An obvious difference was that before the update, the logs contained NMEA GNGST messages, but they did not after the update. I put the Facet into Config mode and connected a web browser to its WiFi Setup web interface.
I opened the GNSS Configuration menu and then the Message Rates menu, expecting to see the usual, long list of the many different message types and their rate settings, but all that was there were the two buttons for “Reset to Surveying Defaults (NMEAx5)” and for “Reset to Logging Defaults (NMEAx5 + RXMx2)”.
I connected u-center again, and using the Configuration View / MSG menu, enabled the GNGST message on UART1 and USB, with an interval value of 1. At that point, SW Maps resumed showing reasonable, numeric values for the estimated errors and accuracies. However, after the next power cycle or reset of the Facet, the GNGST messages were disabled again, as if the configuration that the ESP32 was pushing to ZED-F9P at boot time had a zero for the GNGST rate.
The one and only settings file that was on the Facet’s microSD card contained the line:
message.UBX_NMEA_GST.msgRate=1
Even though that’s set to 1 in the settings file, the ZED-F9P is not getting configured by the ESP32 to enable the GNGST messages.
Thinking that something else had become corrupted in conjunction with the ZED-F9P firmware update, I tried factory resets of the Facet using the method of setting the sizeOfSettings to -1 in the SFE_Facet_Settings_0.txt file on the microSD card (there was only one settings file on the card) and also using the WiFi Setup web interface’s System Configuration / Enable Factory Defaults checkbox.
None of this helped, nor did clearing the web browser’s website data, nor trying a browser on a completely different device. The WiFi Setup web interface’s Message Rates menu still doesn’t show settings for the individual message types. Also, clicking either the “Reset to Surveying Defaults […]” or the “Reset to Logging Defaults […]” buttons doesn’t help. I’ve tried with no microSD card in the Facet at all, including doing a factory reset with no card inserted; still no good.
Google and SparkFun forum searches have not found any matching cases.
I’m attaching (uploading) the Facet’s current settings file.
Does anyone have any other ideas for getting the Message Rates menu to display normally again, and to properly configure the ZED-F9P?
Thanks!
