SoapyUHD + CubicSDR + USRP B210: app does not work #11

Closed dmitryelj closed 6 years ago

dmitryelj commented 7 years ago

Hi.

I have B210, cannot run it with CubicSDR app, that is using SoapyUHD driver. App can detect the receiver, but cannot get data stream from it.

System: Windows 10

Initial receiver settings: usrp_antennas

CubicSDR log: SDR enumerator starting. SoapySDR init.. API Version: v0.6.0 ABI Version: v0.6 Install root: C:\Program Files\PothosSDR Loading modules... ... Available factories...airspy, audio, bladerf, hackrf, lime, miri, null, osmosdr, redpitaya, remote, rtlsdr, sdrplay, uhd -- Loading firmware image: C:\Program Files\UHD\share\uhd\images\usrp_b200_fw.hex... default_input = True default_output = True device_id = 0 ... driver = uhd label = B210 3113F1D name = MyB210 product = B210 serial = 3113F1D type = b200 Make device 3 fpga_version=14.0 fw_version=8.0 mboard_id=B210 mboard_name=MyB210 mboard_serial=3113F1D rx0_antenna=RX2 rx0_id=Unknown (0xffff) rx0_serial= rx0_subdev_name=FE-RX2 rx0_subdev_spec=A:A A:B rx1_antenna=RX2 rx1_id=Unknown (0xffff) rx1_serial= rx1_subdev_name=FE-RX1 rx1_subdev_spec=A:A A:B tx0_antenna=TX/RX tx0_id=Unknown (0xffff) tx0_serial= tx0_subdev_name=FE-TX2 tx0_subdev_spec=A:A A:B tx1_antenna=TX/RX tx1_id=Unknown (0xffff) tx1_serial= tx1_subdev_name=FE-TX1 tx1_subdev_spec=A:A A:B

As CubicSDR developers told, getStreamMTU cannot return 0, that may be an issue.

Other receivers (SDRPlay, RTL-SDR) works correct.

Can it be fixed? Thanks.

PS: I was able to launch the app with this settings: cubuc_uhd

What settings are optimal for USRP?

guruofquality commented 7 years ago

Is the rate testing app working for you? SoapySDRUtil --args="driver=uhd" --rate=10e6 --channels=0 --direction=RX

dmitryelj commented 7 years ago

Yes, it works. rate_test

dmitryelj commented 6 years ago

All works in a last version.
