I'm have 2 XBee Radios and 2 Raspberry Pis. I have the 2 communicating with the XBee radios set to 9600 Baud on the TX and RX lines from the Raspberry Pi.
I recently bumped the XBee radio default Baud rate to 115200 and tried with the Pis. They could not communicate with the modules at all with only the baud rate change. I then used my FTDI cables to connect the XBee to the Pi and it worked fine with the 115200 baud rate.
Howcome the 115200 baud rate works just fine with the FTDI chip, but not the native TX and RX on the headers from the Pi? How can I fix this? Thanks!
