POWER + GPS does not work anymore

Q&A forumCategory: QuestionsPOWER + GPS does not work anymore
Atlanta88 asked 3 weeks ago

I received my RTK2b yersterday with the Xbee bluetooth module. First of all I connect the board to U-center and it works fine. In a second time,  I connected the Bluetooth XBee socket on the board and checked it’s configuration and try to use the board with my phone. When I returned back (U-center) to connect the cable to “GPS+Power” USB port, it doesn’t want to connect anymore (only power).
Did anyone experienced the same issue or have a solution for this problem?

I’m really disappointed, do I have to return it or have you any suggestions please ?
Thanks you for your feedback

Hi Atlanta88,
The situation you describe is really strange.
Make sure you are connecting the USB cable in the POWER+GPS port.
Are some LEDs turned on?
Did you change the configuration of the board before it stopped working?
Let us know as many details as possible.
Best regards,
ArduSimple Team

In the beginning I was able to connect it to a computer (in u-center) via USB and get GPS data. But I noticed that I cannot receive the GPS data on a smartphone via bluetooth (Lefebure or GNSS commander). So I go in U-center : View>Messages View>UBX>CFG>PRT. I enable NMEA protocol and I change the baudrate of the UART2 (38400bps) and send it. After some fast indoor test, it works fine with an external batery for the power. But when I returned back (U-center) to connect the cable to “GPS+Power” USB port, it doesn’t want to connect anymore (only power the board). I tried several cables and none of them work anymore while it still works very well with the Power+Xbee USB port. I also tried to uninstall the port and reinstall it but it still doesn’t work.

For the LEDs , it seems to be normal : turn on (powerer & no RTK ) and blinks (GPS RTK)

Did you only change the port configuration or did you also change another parameter?

Hi ArduSimple,
I received Arduino sons this morning. I followed the tutorial (simpleRTK2B hack #2: unbrick ZED-F9P / use UART1 via USBand) and it worked perfectly, the usb port (power+gps) works again. Thank you for your precious advice and your seriousness
