Hello all,
I am trying to read in a serial line from an xbee using an ESP8266. The problem I'm having is that the ESP8266 is transmitting just fine but will not receive. I am proving this to myself by printing a debug message to the serial port. The confusing thing is that the debug message is showing up on the ESP8266 Rx line and nothing is happening on the Tx line. Guaranteed I'm doing something dumb but I've been staring at it too long now to find it. Thanks for providing fresh eyes!
Code and pic of setup below

// Note! Workshop generates files with Short filenames

yield(); // Required for ESP
