Ok, so I was able to achieve the functionality I was asking for with the help
of various post responses ("set_auto_tr(), gr_stall, and PTT" and "Problem
with symmetric behavior") . I am using set_enable( ) to accomplish my goal,
since my data is not packetized (I am simply using tones). Attached is the
code, http://www.nabble.com/file/p14987034/Switching.py Switching.py ,
which was produced by modifying usrp_nbfm_ptt.py. I am currently using a
python timer to perform the switching, and am looking for a way to speed
this up. (Things only appear to work down to about 10 ms.) I would ideally
like to do the switching at the microsecond level... does anyone have any
suggestions? Can I somehow packetize my data and use the auto t/r switching
mode to achieve this level of switching?
Thanks,
Rob
