srsUE 5G with bladeRF xA9 wont change frequency?

[hearmedrone]

I am running srsUE with bladeRF xa9 - when I start srsUE and defining the config file, the bladeRF outputs what seems to be the default LTE frequency...

ue1.conf

 cat ue1.conf                                                                                                                               ─╯

tx_gain = 3
freq_offset = 0

nof_antennas = 1

srate = 11.52e6

device_name = bladeRF

nof_carriers = 0

[rat.nr]

set RX frequency to 1842500000

not sure what I am missing...

1842.5 MHz does not fall within n78 or the LTE EARFCN that is defined in the config file (2850 = 2630 MHz) - 1842.5 falls within band 75 LTE and n3 NR - which is what the default value is on the ue.conf example given at https://docs.srsran.com/projects/4g/en/latest/app_notes/source/5g_sa_amari/source/index.html

Hi, I am sorry the issue is a bit old and it probably wont help you but if someone encounter this error it is probably just a misconfiguration in the nof_carriers parameters you can try my config file. (I had this issue and solved it).
