To track a paxcounter device with on board GPS and at the same time contribute to TTN coverage mapping, you simply activate the [TTNmapper integration](https://www.thethingsnetwork.org/docs/applications/ttnmapper/) in TTN Console. The formats *plain* and *packed* generate the fields `latitude`, `longitude` and `hdop` required by ttnmapper.
Hereafter described is the default *plain* format, which uses MSB bit numbering.

# Remote control
The device listenes for remote control commands on LoRaWAN Port 2. Multiple commands per downlink are possible by concatenating them.
