ESP32 with LoRa using Arduino IDE

First Visit this Article and follow all instructions

What is LoRa?

LoRa is a wireless data communication technology that uses a radio modulation technique that can be generated by Semtech LoRa transceiver chips.

LoRa allows long range communication of small amounts of data (which means a low bandwidth), high immunity to interference, while minimizing power consumption. So, it allows long distance communication with low power requirements.

LoRa Frequencies

LoRa uses unlicensed frequencies that are available worldwide. These are the most widely used frequencies:

  • 868 MHz for Europe
  • 915 MHz for North America
  • 433 MHz band for Asia

Because these bands are unlicensed, anyone can freely use them without paying or having to get a license. Check the frequencies used in your country.


You can also build a LoRa network using LoRaWAN. The LoRaWAN protocol is a Low Power Wide Area Network (LPWAN) specification derived from LoRa technology standardized by the LoRa Alliance. We won’t explore LoRaWAN in this tutorial, but for more information you can check the LoRa Alliance and The Things Network websites.

Now i have TTGO lora 868. you can use this board If you successfully installed WiFi 32 kit. because this compatible with heltec wifi kit 32 configuration.

How to Use Lora 868 Module with Arduino IDE

  • Open Arduino IDE
  • Click Tools Tab and select “WiFi_Lora_32” Board.
  • Click Tools tab and Select Port.
  • Now Go to File>Example> Lora Library and select Lora Sender example program and Flash it.
  • Now Flash Lora Receiver Program in another Board.
  • Open Serial Monitor For logs.
