Hi all,
I am reading "header_payload_demux" module, I have some questions about it.
1, in "header_payload_demux_impl.cc" line 235, seems need update nread's
value
nread += trigger_offset;
I think without this update, the first header will check failed,
if input data not include complete "d_header_len" ofdm symbols
I don't have that line in my version of the HPD.
This is what I have on L235:
in += trigger_offset * d_itemsize;
And this advances the input buffer pointer to the trigger position.
2, why in "case STATE_HEADER_RX_FAIL:" line 218, need consume one input
item?
To avoid an infinite loop.
3, does the control message's handler function can disturb
"general_work"(like a soft interrupt)?, or these handler only run
before/after "general_work".
They are asynchronous and are always called when a message is passed.
