Hi everyone,

In benchmark, the packet is 23-byte long, inclues preamble, access code, 
header, payload, crc, and 'x55'. Now I want to add a one-byte flag after the 
header. I changed the packet_utils.py make_packet block, add a flag when form 
the new packet. And changed the header length to 9.  However, in terminal, when 
I run benchmark, it shows the new packet is 24-byte long now, including the 
flag byte. But in the file_sink after the byte2chunks and the chunks2symbols, 
the file is not longer than before. In these two files a packet is still 23 
bytes without the new flag byte. So though in tx terminal, it looks like I've 
successfully changed the packet format, but actually, the transmitter didn't 
send this out, it still sends the original packet format.

Has anyone come across this problem before, and could give me some kind 
suggestions on this? Thanks in advance!
