Hi!!

I don't know what's the goal of nx_am_group_t field in serial_header_t
structure. I was looking into the doc but I didn't find anything.

someone knows something?

Historically, AM packets have a group field, to distinguish logical networks that share a physical medium. The serial AM packet has this field so that forwarding from the radio to the serial port can preserve this information.
