- This library is make LoRaWAN 1.0.2 protocol running with ESP32. Only support the ESP32 + LoRa series products made by HelTec Automation(TM), and a LoRa gateway is must needed.
- You may need change some definition in "Commissioning.h" ,"LoRaMac-definitions.h", "board.h"...
- This library is transplanted form https://github.com/Lora-net/LoRaMac-node
- Use RTC and deep sleep mode supported, only few millisecond wake up in a cycle.
To install this library:
- install it using the Arduino Library manager ("Sketch" -> "Include Library" -> "Manage Libraries..."), or
- download a zipfile from github using the "Download ZIP" button and install it using the IDE ("Sketch" -> "Include Library" -> "Add .ZIP Library..."
- clone this git repository into your sketchbook/libraries folder.

The ESP32_LoRaWAN library provides a fairly complete LoRaWAN Class A and Class C implementation, supporting the EU-433 CN-470 EU-868 and US-915 bands. Only a limited number of features was tested using this port on Heltec hardware, so be careful when using any of the untested features.
The following functions included:
- LoRaWAN protocol V1.0.2 Class A and Class C;
- Use ESP32's internal RTC(15KHz);
- All ESP32 + LoRa boards made by Heltec Automation(TM) can use this library;
- Support deepsleep and stop mode;
- An unique license ralate to Chip ID is needed, you can check your license here: http://www.heltec.cn/search/
- Gateway: HT-M01 Mini LoRa Gateway + Raspberry Pi Zero W
- Node: WIFI LoRa 32 V2
- LoRaServer: Aliyun ECS + Ubuntu 16.04 + loraserver.io
- Arudino 18.04
| working band | status |
|---|---|
| EU_433 | not test |
| CN_470_510 | work well |
| EU_863_870 | work well |
| US_902_928 | work with bug |
What certainly works:
- Sending packets uplink, taking into account duty cycling.
- Encryption and message integrity checking;
- Over-the-air activation (OTAA / joining);
- Deep sleep and wake up；
- Class A operation.
What has not been tested:
- Receiving downlink packets in the RX2 window.
- Class B operation.
- Class C operation.
- ABP mode.
What are the known bugs:
- EU_902_928: In OTAA mode, first join request can't be successfully received in gateway.
Coming soon. Before we release the APIs, user can read the .h files.
The only different with a common Arduino library is need a uniqu license. It's ralate to ESP32 Chip ID.
- Use this simple example to read your Chip ID: https://github.com/Heltec-Aaron-Lee/WiFi_Kit_series/tree/master/esp32/libraries/ESP32/examples/ChipID/GetChipID
- http://www.heltec.cn/search/ Open this page and input your ChipID
Only the boards made after August 2018 can be checked from this page, if you have a former version, you can mail to support@heltec.cn and improve you already have a HelTec Automation made board.
