// -------------------- DOT LIBRARY REQUIRED ------------------------------//
// * Because these example programs can be used for both mDot and xDot //
// devices, the LoRa stack is not included. The libmDot library should //
// be imported if building for mDot devices. The libxDot library //
// should be imported if building for xDot devices. //

// -------------------- DEFINITIONS REQUIRED ---------------------------- //
// mDot - add define for FOTA in mbed_app.json or on command line //
// Command line //
// mbed compile -t GCC_ARM -m MTS_MDOT_F411RE -DFOTA=1 //
// mbed_app.json //
// { //
// "macros": [ //
// "FOTA=1" //
// ] //
// } //
// //
// xDot - DO NOT define FOTA, there is no file system support available //
// Only multicast is supported for xDot, external MCU and Flash //
// are required to support Fragmentation //
////////////////////////////////////////////////////////////////////////////

// * these options must match the settings on your gateway //
// * edit their values to match your configuration //
// * frequency sub band is only relevant for the 915 bands //
// * either the network name and passphrase can be used or //
