var bufferData = getPacketBuffer ();
 
var packet = new LoRaPacket (bufferData, {
    nwkSKey,
    appSKey,
    encoding: 'hex'
});
 
// from String
var bufferData = getPacketString ();
 
var packet = new LoRaPacket (bufferData, {
    nwkSKey,
    appSKey,
    encoding: 'hex'
},
{
    encoding: 'base64'
});
