Transmission timeouts

Open sh123 opened this issue 3 years ago • 0 comments

Hello, having some problems transmitting with SoapySDR remote through SDRAngel:

  • Built SDRAngel from master by using these instructions https://github.com/f4exb/sdrangel/wiki/Compile-from-source-in-Linux
  • Started SoapySDRServer on the computer running Linux and started SDRAngel on the same computer
    • Also, tried to run between remotely controlled Raspberry PI with SoapySDRServer and PC with SDRAngel with the same results (this is what is trying to achieve)
  • Created sink and selected SoapySDR[1:0] remote
  • Trying to transmit NFM CW beacon, beacon is transmitted distorted with lots of overrun messages
2021-03-26 22:22:19.110 (W) SoapySDROutputThread::run: timeout: flags: 0 timeNs: 0 timeoutUs: 250000
2021-03-26 22:22:21.372 (W) SampleSourceFifo::write: overrrun (read too slow) dropping 256000 samples
  • Receive through remote SoapySDR works fine
  • Transmission through non-remote SoapySDR works fine
  • Tried to change various network parameters as specified in https://github.com/pothosware/SoapyRemote/wiki, but it did not help

Is it problem with SoapySDRServer not being able to consume samples fast enough or SDRAngel timing out? It seems to come from the client side, not getting ack from the sever.

Both were running on the same computer during the test.
