[Discuss-gnuradio] Transmitting and receiving alternatively with same USRP

[Sachin Katti]

Hi everyone

I am trying to write an application (to implement a TDMA MAC) in which a node alternatively transmits and receives using the GMSK code. Basically I want to implement the following functionality
1) After I receive a packet, I want to be able to shut down or stall the receive side of the graph
2) Now transmit a packet and after its done, re-enable the receive side.

I tried to use a mechanism similar to tunnel.py already included in the distribution, but I cannot get the one to one ratio which I want, 
i.e. sometimes the transmit path doesnt get scheduled for a while since the receive path blocks are active and are receiving packets. Has anyone tried something similar before? Any pointers would be greatly appreciated.

Thanks
Sachin
