arduino/sigfox_downlink/sigfox_downlink.ino

// ---------------------------------------------------------------------
// This file is a example for use the library armapi with
// ARM NANO (NANO_LP with sigfox) on arduino board.
//
// This software send periodically 'Hello Sigfox' to Sigfox network
// and get the message from sigfox to on/off the led.
// The first byte is user to switch on/off the led.
// - If the byte is 0 the led is switch to off.
// - If the byte is different of 0 the led is switch to on.
