Message Types

This is a list of all message types as extracted from the Pax mobile application. The names are identical to what the app calls them.

At least the names and IDs are known to be accurate. The descriptions were determined through reverse engineering the code, and the device support was also determined from seeing which packets the device sent at what times.
