PHP Cayenne LPP encoder and decoder
===================================

[](#php-cayenne-lpp-encoder-and-decoder)

[![Build Status](https://camo.githubusercontent.com/b82c1b2b57a3a952dd13be848b12699517ed544c35b4be604c50f2627ee8fbcd/68747470733a2f2f7472617669732d63692e6f72672f506f7765722d4c616e2f636179656e6e652d6c70702e7376673f6272616e63683d6d6173746572)](https://travis-ci.org/Power-Lan/cayenne-lpp)

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

Encoder exemple
---------------

[](#encoder-exemple)

```
$encoder = new CayenneLPP\Encoder;
$encoder->addTemperature(0, 20.0);
$encoder->addTemperature(1, 21.0);
$buffer = $encoder->getBuffer();
$size = $encoder->getSize();

```

Decoder exemple
---------------

[](#decoder-exemple)

The decoder implements the `Countable` interface. It's allow to known how many dataset are in the binary stream.

```
$decoded = new CayenneLPP\Decoder(hex2bin('00860070013AFFFF' . '0186FFFF0070013A'));
$nbChannels = count($decoded);

```

The decoder implements `Iterator` interface. Each item are array which contains the data channel index, the data type, and the data decoded.

```
$decoded = new CayenneLPP\Decoder(hex2bin('00860070013AFFFF' . '0186FFFF0070013A'));
$nbChannels = count($decoded);
foreach ($decoded as $data) {
  $channel = $data['channel'];
  $type = $data['type'];
  $data = $data['data'];
}

```
