Detailed Description

The protocol used for data transmission requires each message to be tagged with a source ID, that should be unique on any given system

Source IDs range from 0 to 127, but are best represented as two digit hexadecimal numbers, with the first number indicating a device or sensor type and the second digit free to be used as a local device ID. In current implementations these IDs are baked into device software or firmware, but may be configurable for future devices.

IDs in the 0x00 - 0x0F range are an exception, and each value represents a different software source type.

Any ID number or range not allocated here is considered reserved, although software should still process data with unknown source ID numbers by default.
