XBEE Adapter Board TX/RX pins

Post by KehvAntile »

I am attempting to use XBee adapters with a pair of XBee modules to do some tinkering. During the initial loopback testing I ran into an issue where the remote XBee didn't seem to be sending any signals back to the control module, despite having a jumper wire on the breadboard between the TX and RX breakout pins.

I was able to get the remote XBee to respond properly by putting a jumper on the TX and RX pins on the FTDI side of the adapter, which worked for that test, but I would like to determine why I might be having issues with the breadboard-side breakout pins.

Could you post clear, detailed pictures of both sides of your board showing any soldering you have done and the connections to it?

This does not work despite connecting to the RX and TX pins (the other end of this is a Teensy acting as a USB To Serial converter)
