Hello
I try to configure channel 1 on B210 with osmocom_fft but I can't
access to it
the cmd :
SoapySDRUtil --probe="driver=uhd,type=b200"
shows :
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
these 2 lines are working fine
SoapySDRUtil --args="driver=uhd" --rate=10e6 --channels=0 --direction=RX
SoapySDRUtil --args="driver=uhd" --rate=10e6 --channels=1 --direction=RX
Trying all these lines are always addressing channel 0
osmocom_fft -a uhd -s 1000000 -g 40 -f 392M
osmocom_fft -a uhd -s 1000000 -g 40 -f 392M -v
osmocom_fft -a uhd,nchan=0,subdev=A:B -s 1000000 -g 40 -f 392M -A TX/RX
osmocom_fft -a uhd,nchan=0,subdev=A:B -s 1000000 -g 40 -f 392M -A RX2
osmocom_fft -a uhd -s 1000000 -g 40 -f 392M -A FE-RX2
osmocom_fft -a uhd,subdev=FE-RX2 -s 1000000 -g 40 -f 392M -A RX2
osmocom_fft -a uhd,"nchan=FE-TX1","subdev=A:A A:B" -s 1000000 -g 40 -f
392M -A TX/RX
What is the exact usage of osmocom_fft to access channel 1 ? or the
exact usage of soapy driver ?
Thanks for answer

For osmosdr applications:
uhd,type=b200,nchan=1,subdev=A:A gives you the first channel
uhd,type=b200,nchan=1,subdev=A:B gives you the second channel
