Thanks jaap, here is more information:
Header is 1byte and its format
7 6 5 4 3 2 1 0 bit
type XXXXX
Messages is 20 bytes
Binary data is unknown
After getting the first 3 bits from header:
Format of this payload will depend on the first 3 bits of header (bit Type field)
-------------------------------------------------
Header|Message if first 3 bits (type) is 000
Header|Binary Data 001
Header|Message|Binary Data 111
-------------------------------------------------

Hi,
You'll have to provide a little more detail than this. What size are
header, message and data? Are they packed in a byte? format stuff like
that.
Thanx,
Jaap
