BresserWeatherSensorLW LoRaWAN Payload Codec

LoRaWAN Codec API compliant codec for BresserWeatherSensorLW.

This package provides uplink and downlink encoding/decoding functions for use with The Things Network, The Things Stack, Helium, and other LoRaWAN platforms.

Features

• Uplink decoding: Converts sensor payload bytes to JSON objects.
• Downlink encoding: Converts JSON commands to bytes for device control.
• Downlink decoding: Converts downlink bytes to JSON for verification.
• LoRaWAN Codec API compliant: Works with TTN, TTS, and similar platforms.

Installation

npm install bresserweathersensorlw-codec

Usage

const codec = require('bresserweathersensorlw-codec');

// Decode uplink
const uplink = codec.decodeUplink({ bytes: Buffer.from([/* uplink bytes */]), fPort: 1 });
console.log(uplink);

// Encode downlink
const downlink = codec.encodeDownlink({ data: { sleep_interval: 300 }, fPort: 0x31 });
console.log(downlink);

// Decode downlink
const decodedDownlink = codec.decodeDownlink({ bytes: Buffer.from([0x01, 0x2C]), fPort: 0x31 });
console.log(decodedDownlink);

API
