Hello all,
I noticed somthing strange today when trying to use GRC with my xtrx. When I use the test_xtrx command and look at the output, I get a strong tone that starts and stops cleanly. But, when I try to use the osmocom Sink, it appears that SoapySDR 'hangs' for almost 10 seconds on SoapyXTRX::activateStream(TX) 0 Samples per packet; res = 0, and then transmits my actual desired burst. The real problem is that during this 'hanging' state, the xtrx is actually outputting RF energy. I have attached two pictures. Both are screenshots captured on a B205-mini.
test_xtrx -T -S4e6 -l2 -C5000 -L1000 -F 300000000
(Please ignore the harmonic image, focus on clean tx start and stop)
Custom flowgraph - you can see the burst, but before that a tone is present for nearly 10 seconds
