Testing basic mdot with external Interrupt

Dependencies:   libmDot mbed-rtos mbed-src

Fork of mDot_test_rx by Mike Fiore

LoRaWAN Network Configuration

For DevEUI, AppEUI, AppKey configuration to specific network, please see lines 10 to 18.

If using with an 8 channel gateway define config_frequency_sub_band at line 16. Setting config_frequency_sub_band to '1' will limit the device to using just the first eight (8) channels starting at 902.3 MHz.

Free Running vs Interrupt

At line 117 you can change the program from waiting for external interrupts to free-running by changing msg_rdy to be equal to 'true'.
