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

[Sandi Suhendro]

Dear Andre,
it may work with ue.conf, for make ue, but I need to set srsenb to LNAL.

example on enb.conf:
[rf]
dl_earfcn = 1600
tx_gain = 80
rx_gain = 40

#device_name = soapy
#device_args = "rxant=LNAL,txant=BAND1"

its not work!

please advise.

DUO / Sandi
