mir_sdr_2500_StreamInit() Error 0x00000001

[dtaviation]

Hi,

Would someone be able to suggest why intialising the connection to the radio might sometimes fail:

mir_sdr_usb_USB DLL: Revision 0.1.1
mir_sdr_2500_Init: fnaddr = 15
mir_sdr_2500_Init: adjusting squelch trim 0x1, rx gating enable 1, tx_trim 0, reg2 = 0x4801
mir_sdr_2500_StreamInit: Open failed
initHw: mir_sdr_2500_StreamInit() Error 0x00000001
mir_sdr_Init: initState returns error 7

HW: 2014 Mac Mini, SW: Fedora 23, gr-osmosdr.

Thanks,
Dave

Hi,

Can you confirm that you are using the official driver with SoapySDR? Can you post the output of...

SoapySDRUtil --probe=sdrplay

Thanks and best regards,

Thanks for that, this shows a problem. However, sometimes the radio starts ok.


$ SoapySDRUtil --probe=sdrplay

The SoapySDRUtil command was very helpful, thanks.

After having:
1) Removed the offending libraries, which were put there by a build of SoapyRemote
2) Reinstalling your API, and
2) Rebuilding gr-osmosdr and SoapySDR

I now have a working radio again.

Excellent support.
