Basic RX/TX example, this is the firmware that LoDev S76S comes with initially.
Dependencies: mbed SX1276RonothLib
LoDev RX/TX Example
Transmit
By default LoDev comes on in receive mode. To switch to transmit mode, connect PC2 to 3.3v and press the reset switch. In TX mode the blue LED is normally off and blinks on briefly when transmitting.
Receive
When in RX mode the LED is normally on and turns off briefly when receiving a packet. This is the default mode.
