[Discuss-gnuradio] About the simple_mac.py in bbn80211

2009-10-15 Thread Chen Chen
Hi,

I download the bbn80211, and want to use the simple_mac.py to do some
experiment. But this code is not compile with the new version of GNU Radio,
thus cause many errors. Does anyone do the modification of this script so
that it can work with the new GNU Radio version?

Thank you very much.

Best,

Chen Chen

[Discuss-gnuradio] RX error in USRP

2009-10-15 Thread Álvaro Fernández-Villamil
Hi,

Some days ago I wrote here, but I received no answer. I would be very glad
if someone could help me... My message was the next:

"I had an "Error calling tune on subdevice" in the RX 750-1050 daughterboard
while I was running "usrp_two_tone_loopback" in GRC. It was working
successfully but I touched my SMA Antenna and suddendly it began to fail and
when I tried to restart the program, the system gave me this error. I guess
something must be wrong with function "tune", but I don't know what to do in
order to solve the problem. Any idea? Thanks in advance!"

Everything point to the function called tune, but I don't understand why the
TX frequency can be tuned perfectly and the RX one can not...

Thanks again

Alvaro

[Discuss-gnuradio] External triggering using the micro-controller ?

2009-10-15 Thread Per Zetterberg

Hi,

I wonder if it would be possible to program the micro-controller of an 
USRP1 so that it polls a pin in order to trigger start of 
transmission/reception  ?
