README

This library can encode and decode data stream for LoraWan and SigFox devices which use Cayenne LPP encoding.

Installation

You can install the package via composer:

composer require jalallinux/php-cayenne-lpp

Usage

Encoder

$encoder = new Encoder();
$encoder->addAnalogInput(2, 4.2)
    ->addRelativeHumidity(3, 32.0)
    ->addTemperature(4, 28.7)
    ->addBarometricPressure(5, 851.3)
    ->addAnalogOutput(6, 4.45);

$hex = bin2hex($encoder->getBuffer());
/**
 * RESULT
 * 020201a40368400467011f05732141060301bd
 */

Decoder

$decoder = new Decoder(hex2bin('020201a40368400467011f05732141060301bd'));
$data = $decoder->data;
/**
 * RESULT
 * [
 *  0 => [
 *    "channel" => 2
 *    "type" => 2
 *    "typeName" => "analogInput"
 *    "data" => [
