-# AT-CMD implementation of at-lora command set
-
-This example implements the AT command set as used by Seeed in the LoRa-E5 series of boards, but in the form of a TinyGo program that provides a serial interface. 
-
-See https://files.seeedstudio.com/products/317990687/res/LoRa-E5%20AT%20Command%20Specification_V1.0%20.pdf for more information.
