ZED F9P board stops communicating over USB-C

GPS/GNSS Development Boards

Hello,

I’ve previously set up two ZED F9P boards in wireless base/rover configurations without issues. This third board seems problematic. I’d configured it to be a Rover through u-center, saved settings and disconnected. At the next power-up, the board LEDs lit up the usual way (the PPS one albeit quite inconsistent), but the board offered no communication whatsoever. Reconnecting it to u-center does not work - the board is recognized as a “ublox gnss receiver” and ucenter ‘connects’ to it - however nothing populates afterwards (no packets/msgs etc). Querying the firmware version (or uploading new firmware) does not work either.

Is there a way to force-reset, or force-upload firmware to the board? Any insights on why the board fails to communicate with u-center perhaps?

Thanks.

You should be able to reset the module back to factory settings in case something unseen happened during that use with u-center. https://github.com/sparkfun/SparkFun_Ub … esetModule

Thanks, that worked.

FYI, I had to add a few more lines of auto-baud rates (the library seems to look for only two).
