Hi Andreas, the status packets come from the original CANO firmware (and I think they come for the MRT sets). There's no distinction or specific order in the status packets that I made in the firmware. The status packet contain indded a 'counter' ancoded in the 'statusBits'. But beware that the 'main' packet is encoded different from firmware release. It seems like older transponder (that have NO status) are coded differently from the ones that have status packets. Please check the two functions encodeTransponderNoStatus and encodeTransponderWithStatus in TransponderEncoding.cs, or use your captured 'main' packet. Sorry if this sound too technical, if you need further I'll be glad to help. To check the correct packet, re-encode them and check that the bitstream matches.
