Re: Help For Packet Reception in GNU Radio

Hi Cinaed

hdr simply means header format. I am adding preamble and header to the 

payload (data packet ) using 

digital.header_format_default(digital.packet_utils.default_access_code, 0) 

Thank You

Hi Rohith - in the Protocol Formatter,  the hdr_format, I'm fairly
certain the hdr denotes "High Dynamic Range" used in imaging - TV images
for instance.

In which case, it may easily generate 4 times the data then your
sentence contains in bits.
