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
