Dear USRP Community,
I need to do a realistic loopback TX-RX communication (via a feeder
and attenuator) of my B205mini device.
I took the examples from tx_samples_c.c and rx_samples_c.c, and tried
running them as two different POSIX threads. However, this way I could
get only transmission working, without any reception. When trying from
GNU Radio - both the source and sink modules work simultaneously
without any problem, meaning that I have done something really wrong
in my approach...
Could you please advise what is the correct structural pattern for
simultaneous RX and TX on a single USRP device via the UHD framework?
Best regards,
Varban
Varban:
There's an example that does this:
txrx_loopback_to_file
You can look at the source code of that example to get some ideas of how
to properly structure such a thing.
