== 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.<br>

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

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.<br>

==Usage==

===Lora gateway--MicroPython===
'''[https://github.com/Makerfabs/MakePython-Lora Github:MakePython-Lora]'''

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.<br>
<br>
You can get ESP32 from here: [https://www.makerfabs.com/makepython-esp32.html Makepython ESP32]<br>

<br>
Step:<br>
1. Plug the antenna and MakePython ESP32 into MakePython Lora, assemble into Lora Gateway, and connect the USB cable.<br>
2. Download the code from here: [https://github.com/Makerfabs/MakePython-Lora/tree/master/Lora%20Gateway/Code_433M Code_433M]. (Note: Please select different files for downloading [https://github.com/Makerfabs/MakePython-Lora/tree/master/Lora%20Gateway Lora] modules in different frequency bands)<br>
3. Upload all the xxx.py files in the Code_433M file to two ESP32 Lora Gateeay.<br>
[[File:MakePython_Lora_9.jpg|700px]]<br>
4.After the upload is successful, press the MakePython ESP32 reset button.<br>
5.Test Results<br>
Two people are measuring in a city with a complex environment:<br>

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

===Lora gateway--Arduino===
Note: If you purchased it before December 2020, you need to weld two 0Ω resistors at R6, R9. Purchases made after December 2020 are not required.<br>
*Prepare the Makepython ESP32 module.<br>
*You can get the code from here: [https://github.com/Makerfabs/MakePython-Lora/tree/master/RadioLib_example Github].<br>
*Install the ESP32 Board on the Arduino IDE.([https://github.com/Makerfabs/Makerfabs_FAQ/tree/master/Arduino_ESP32 link to the installation tutorial])<br>
*Install RadioLib.h library.<br>
*Defines the frequency of the Lora module in the code '''transmit.ino'''.<br>
*Upload the code '''transmit.ino''' to the MakePython ESP32 module.<br>
*Assemble Makepython ESP32 module and the Makepython Lora, and power on.<br>
*The Lora module loops a message "Hello World" to the nearby same band module.<br>
*Similarly, when the ESP32 module is uploaded code '''receive.ino''', it receives messages from nearby modules in the same band.<br>
