Introduction

The Makepython Lora transceivers feature the LoRaTM long range modem that provides ultra-long range spread spectrum communication and high interference immunity whilst minimising current consumption.

Makepython Lora need to be work with Makepython ESP32, can be acted as a Lora Gateway.

The Makepython Lora offers bandwidth options ranging from 7.8125kHz to 500 kHz with spreading factors ranging from 6 to 12, there are three choice of the working frequency.

Item Lora Moduie Working frequency
MakePython Lora 433M RFM98W-433MHz 433MHz
MakePython Lora 868M RFM98W-868MHz 868MHz

Usage

The routine uses MicroPython for programming, and two Lora gateways are used for long-distance communication in the complex environment of the city. The actual test distance reaches 2.8 kilometers. If the interference is small in the suburbs, the distance will be farther.

You can get ESP32 from here: Makepython ESP32

Step:
1. Plug the antenna and MakePython ESP32 into MakePython Lora, assemble into Lora Gateway, and connect the USB cable.
2. Download the code from here: Code_433M. (Note: Please select different files for downloading Lora modules in different frequency bands)
3. Upload all the xxx.py files in the Code_433M file to two ESP32 Lora Gateeay.

4.After the upload is successful, press the MakePython ESP32 reset button, the screen displays the signal sensitivity, ESP32 ID number and received data number.

5.Test Results
Two people are measuring in a city with a complex environment:

The test distance is 2.8 kilometers, if you go to the suburbs, the distance will be farther.
