[W-MBUS] How can we define, where a data package (sending out of the module) starts and when does it stops.

“on the air: the preamble defines the start. The end is simply defined based on the length byte sent in the beginning of the messsage.

On the UART (from the module): The first byte is the length byte. Again is defined by this length byte.
