The communication with the simpleRTK2BLite has stopped working and now we can not connect it to the ublox center.
Is there a way to fix it in a similar way as described in https://www.ardusimple.com/simplertk2b-hack-3/ for the simpleRTK2B board?
Is there any procedure to recover the default configuration?
Thanks in advance
Check that you are not trying to communicate at the wrong baudrate or that you havent disabled uart1 by disabling uart1 protocol in UBX.
Ultimately safeboot process should recover any unit. The procedure is the same as with simpleRTK2B (power with safeboot to GND), the only difference is that with lite you communicate using the bottom headers tx and rx.
