Hi fe8769 - Although you're clearly trying to use an Ettus B210 USRP, your query is really about the API used by SoapySDRUtil and osmocom_fft to access the SDR hardware. I'd guess that most folks here use UHD -- and do not use SoapySDR or gr-osmosdr -- for their USRP work -- though there are probably a few outliers, and I'd encourage those folks to pipe up if they know how to access a B210 via those interfaces! I think you'll have better luck making your inquiry on the email lists / forums for SoapySDR and/or gr-osmosdr. Good luck! - MLD -- Michael Dickens Ettus Research Technical Support Email: supp...@ettus.com Web: https://ettus.com/
