Hello Everyone, Why does the Protocol Formatter block add additional 4 bytes of data to the Header? For example, take the following case (Here is a snapshot of GRC and the .grc file is attached with the email . ) [image: image.png]
This .grc file (taken from the examples of /src/share/gnuradio/examples/digital/packet/) has two Fromat Obj.'s defined . One of them is "*digital.packet_utils.default_access_code*" and Second one is the similar thing with additional counter (which appends 4 bytes of running counter data to the header) When I execute the "*digital.packet_utils.default_access_code*" in python, it gives me 8 bytes of data. (*ac dd a4 e2 f2 8c 20 fc *) but the output of Protocol Formatter is the following 12 bytes of data in which last 4 bytes of 12 bytes are appended with (*00 11 00 11*) [image: image.png] can anyone of you please point out me the reason why it is appending those 4 bytes of data? Thanks for your time and help. Ash
