RTK Facet L-Band PointPerfect issues + FW Update issues

GPS/GNSS Development Boards

Hello, Recently recieved a replacement unit as the original unit was incorrect version. When I tried to setup PointPerfect, i was getting an error of ZTP Failed even though I could see it join my WIFI network. As such i followed the recommendations in post [SparkFun RTK Facet L-Band configuration PointPerfect to make sure my firmware was up to date. My device was on 2.2 and i saw there was a version 2.5 so I followed the instructions in Updating RTK Firmware guide. According to the console output the firmware update succeeded but the device never rebooted as the console message said it would. I tried changing the baud rate to 115200 as it suggested in the guide as well as trying to roll back to 2.2 with no success. The device still shows up on USB and i can attempt re-flashing the device but the screen, button and charge lights have become unresponsive.

i noticed that the ESP32 was constantly rebooting, I tried a few other things and then ended up barrowing a windows computer and got 2.5 loaded and the device is now booting. I would definitly like to understand what i was doing wrong n the linux machine as well but I am still having issues with PointPerfect correction getting its keys.

The device still shows up on USB and i can attempt re-flashing the device but the screen, button and charge lights have become unresponsive.

I apologize for this. We’ve seen this behavior too. The GUI updates the firmware successfully but the device doesn’t reboot. To aid in this, we’ve added a reset button to the GUI (shown below):

Please don’t worry, any device can always be recovered and firmware changed.

WRT to getting the L-Band keys, it looks like your device was not whitelisted before it left our factory. It’s been added now. Please re-connect to WiFi and it should obtain keys.

Please let us know if you have any other issues!

Looks like it is getting keys now, Thanks.

Just unfortunate that it has taken 2 months after spending 1500$ to get to a point where i can start using it.
