Hi!
I am trying to get the dragonboard410c which I have connected to a remote Xbee series 1 module to transmit the data on its GPIO pins through the remote Xbee to another local Xbee connected to my PC. Currently, I am running Linux on the dragonboard410c and I have two jumper cables connected from pins 5 and 7 on its low-speed expansion header to DIN and DOUT on the XBee, respectfully. Right now, I just need help figuring out how to access the UART pins 5 and 7 on Linux terminal and how to send data through them that can be received on the local Xbee connected to my PC.
The bellow image gives an idea of what I am trying to achieve:
