[srslte-users] LimeSDR/SoapySDR List Antenna change in source code

[Andre Puschmann]

Hey,

you can control the antenna setting through the device arguments. For
example, to use the LimeSDR in the higher frequency bands, put
"device_args = rxant=LNAH,txant=BAND2" in your ue.conf.

Hope that helps.

Thanks
Andre
