pyrn2483's Introduction

RN2483

Small Python library to interface the RN2483 (Data-Sheet, User-Guide) LoRa module over a serial connection. Once connected, the library allows to receive and transmit data over LoRa directly with the module. Supports micropython and desktop machines.

Installation

Clone this repository git clone https://github.com/lorenzschmid/pyRN2483.git
Change into the new directory cd rn2483
Install package with pip: pip install .

Micropython Example

import pyb
from lora import LoRa

debug = True        # print debug information of current command in REPL
serial_port = 1     # indicate UART port LoRa module is connected to
timeout = 5000      # timeout of serial and lora reception
tx_data = "Hello!"  # data to be send (leave empty for reception)

# connect to module
lora = LoRa(serial_port, timeout, timeout, debug)

if tx_data != "":
    # transmit data
    lora.send_str(tx_data)
else:
    # receive and print data
    rx_str = lora.recv_str()
    print(rx_str)

Command Line Interface

Comes with a command line interface which works as following:

usage: rn2483 [-h] [-d] [-t TRANSMIT] [-r RECEIVE] [-p PORT]

Receive and transmit data via rn2483 module.

optional arguments:
  -h, --help            show this help message and exit
  -d, --debug           Debug mode
  -t TRANSMIT, --transmit TRANSMIT
                        Data to transmit
  -r RECEIVE, --receive RECEIVE
                        Timeout upon reception (in ms)
  -p PORT, --port PORT  Serial Port e.g. pyb, ttyUSB1,
                        /dev/tty.usbserial-A5046HZ5
