LoRa

Python Library for Microchip RN2XX3 LoRa Module.

Python Library

Turta_LoRa library is responsible for handling all LoRa communication.

To make Raspberry Pi communicate with the LoRa module, you should swap the serial ports of the Raspbian OS. Set "/dev/ttyAMA0" to 'serial0'. Also, disable the console on 'serial0'. For a how-to, visit swapping the serial ports topic.

Initialization

Add the following statement to the top of your Python code.

from turta_lorahat import Turta_LoRa

Then, create an instance of the RN2XX3 class.

lora = Turta_LoRa.RN2XX3()

Now you're ready to access the library by calling its instance.
