README

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

Encoder exemple

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

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'];
}
