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.
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|
|MakePython Lora 915M||RFM98W-915MHz||915MHz|
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
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.
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.
