Devin Alexander / Mbed OS MAX326xxFTHR_LoRa_RFM95_PingPong_Example

This program is guided to help establish a connection between two RFM95 900MHz LoRa radio modules using Maxim Integrated's Feather MCUs (MAX32630FTHR Mbed and the MAX32620FTHR Mbed). Once the radios are configured after powering on and if the radios are wired correctly, the two radios will self identify as either a master or a slave, and will then proceed to PING and PONG back and forth. Information about what is happening between the radios can be seen if the two boards are hooked up to a USB COM port through the included DAPLINK/MAX32625PICO modules.
