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
