[Discuss-gnuradio] Re: Packet Transmission

[William Sherman]

Well that certainly makes things trickier.

Thinking through the problem: couldn't you detect when the packet had 
been transmitted by inserting a packet of 'voltage 0's' after your real 
packet into transmit_path's flowgraph. Then you could poll the msgq in 
message_source until the queue is empty. Then you know your real packet 
has been actually transmitted, while your "0 packet" could still be in 
the process of transmitting (but as transmitting 0 voltage equivalent to 
not transmitting). Thus you could perform sensing/receiving as soon as 
the queue was empty.

Would this be the correct approach to solving the problem I had in the 
original post?
