Hi RAK Team

I found a bug in the GPS6digitPrecision Decoder for TTN. If I use it as you published here in the git
https://github.com/RAKWireless/RUI_LoRa_node_payload_decoder/blob/master/RUISensorDataDecoder_GPS6digitPrecison_for_TTN.js

With the Payload: 01 88 07 29 C2 01 22 7B 00 D8 72 08 02 01 87 03 71 00 27 FF 86 04 12 05 86 00 40 00 7C FF C4 09 02 08 52 0A 02 00 0F 0B 02 F8 35

The out put will be:
{
"altitude": "19131274.2m",
"latitude": "120.177153°",
"longitude": "578.486488°",
"magnetometer_y": "0.15μT",
"magnetometer_z": "-19.95μT"
}

With the standard decoder it is - this one https://github.com/RAKWireless/RUI_LoRa_node_payload_decoder/blob/master/RUISensorDataDecoder_for_TTN.js:
{
"acceleration_x": "0.039g",
"acceleration_y": "-0.122g",
"acceleration_z": "1.042g",
"altitude": "554.1m",
"battery": "3.91V",
"gyroscope_x": "0.64°/s",
"gyroscope_y": "1.24°/s",
"gyroscope_z": "-0.6°/s",
"latitude": "46.9442°",
"longitude": "7.4363°",
"magnetometer_x": "21.3μT",
"magnetometer_y": "0.15μT",
"magnetometer_z": "-19.95μT"
}

I did found the error in the JS file and it is in the case 0x0188:// GPS - The decoder should not change the Substring value! The Payload size is always the same - as defined by the openmobilealliance.org the precision is only for the decoder

If I try to use the decoder I get:
