Devin Alexander / Mbed OS MAX326xxFTHR_LoRa_RFM95

got this sample program for 2+ sx1276 modules to communicate in a ping pong fashion. This program has been tested and verified to run with 915MHz Hope RFM95 modules running with MAX32620FTHR and MAX32630FTHR micro controllers.

Dependencies:   BMI160 BufferedSerial SX1276GenericLib USBDeviceHT max32630fthr

Fork of STM32L0_LoRa by Helmut Tschemernjak
