Python library to send and receive data over LoRa via a rf95modem

rf95modem-py

Python library to send and receive data over LoRa PHY via a serial connection to a rf95modem.

This library was tested against the rf95modem commit 8f163aa, slightly after version 0.7.3.

Library

The primary focus of this library is to send and receive data via LoRa's physical layer, LoRa PHY, with the help of a rf95modem.

Therefore the rf95modem.reader.Rf95Reader. allows direct interaction with a connected rf95modem, including configuration changes, sending, and receiving raw LoRa PHY messages. This Rf95Reader extends serial.threaded.LineReader from pySerial.

The following short code example demonstrates how to use this library.

import serial
import serial.threaded
import sys
import time

import rf95modem


if __name__ == '__main__':
    ser = serial.serial_for_url('/dev/ttyUSB1', baudrate=115200, timeout=1)
    with serial.threaded.ReaderThread(ser, rf95modem.Rf95Reader) as rf95:
        rf95.rx_handlers.append(lambda rx: print(rx))

        rf95.mode(rf95modem.ModemMode.FAST_SHORT_RANGE)
        rf95.frequency(868.23)

        rf95.transmit(b"hello world")

        print(rf95.fetch_status())

        while True:
            # Wait for incoming messages to be printed by our handler.
            try:
                time.sleep(0.1)
            except KeyboardInterrupt:
                sys.exit(0)
