Got it figured out. If anyone has this trouble in the future. If you are using a pro mini at 3.3V and 8mhz it isn't compatible with 115200 baud for serial communications. Switch BAUD_RATE to 57600 in MyConfig.h and it will fix the problem. You'll also need to change the baud to match in your demo.items, or whatever your site is called. (for openhab)
