Hi guys! After a firmware update from 1003 to 1009 my device (xbee 3) stopped sending and receiving commands via uart. The SPI pins are all enabled by default since the update. I tried to disable them but the XCTU says that the AT command are incorrect, I also connected to my xbee via bluetooth tough the app and its still the same error. I read the hardware manual, and turn on the xbee with de DIN pin to ground to restore the uart but nothing happened.
We are developing a product based on xbee 3 (more than 100 devices were bought), so we need to solve this or will move to another hardware solution.
The only way I can communicate with my xbee is via radio, the uart is inactive and my custom board is not using the spi port. When I try to update via radio with a coordinator board the xctu says that there was an OTA error, something about size mismatch.
Well I have entered to bootloader mode and updated the fw to 100A version, the uart still not working, but it is not a hardware issue because in bootloader mode I sended and received data via Xmodem with tera term.
