LORAWAN Librairie for Arduino and SX1276/2 lora chip

This library is not maintain anymore, please have a look to https://github.com/ngraziano/LMICPP-Arduino and example : examples/balise

Introduction

• Based on LMIC librairy.
• Modified to get C++ style.
• Only class A device (no class B)
• Add some sleep of arduino board.

Tested with Arduino Pro Mini and RFM95 on EU868 frequencies.

Usage

Work with platformio.

In src directory create a file named lorakeys.h wich contain the keys declared in network (for exemple https://www.thethingsnetwork.org)

Exemple of file:

#include <Arduino.h>
// This EUI must be in little-endian format, so least-significant-byte
// first. When copying an EUI from ttnctl output, this means to reverse
// the bytes. For TTN issued EUIs the last bytes should be 0xD5, 0xB3,
// 0x70.
static const uint8_t PROGMEM APPEUI[8]={ 0xXX, 0xXX, 0xXX, 0xXX, 0xXX, 0xD5, 0xB3, 0x70 };

// This should also be in little endian format, see above.
static const uint8_t PROGMEM DEVEUI[8]={ 0x02, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00 };

// This key should be in big endian format (or, since it is not really a
// number but a block of memory, endianness does not really apply). In
// practice, a key taken from ttnctl can be copied as-is.
// The key shown here is the semtech default key.
static const uint8_t PROGMEM APPKEY[16] = { 0x2B, 0x7E, 0x15, 0x16, 0x28, 0xAE, 0xD2, 0xA6, 0xAB, 0xF7, 0x15, 0x88, 0x09, 0xCF, 0x4F, 0x3C };

In main.cpp replace the content of do_send() with the data you want to send.

Main functional change from LMIC

• Try to implement ADR a little more correctl:
  • Handle Txpower
  • ADR_ACK_LIMIT set to 64
  • ADR_ACK_DELAY set to 32
• Correct set of power for SX1276
