Hi! Trying to get OAI UE to work using LimeSDRMini. Tried various .ini files and always end up with the same result with failing TX freq setting:
Connecting to device: LimeSDR Mini, media=USB 3.0, module=FT601, addr=24607:1027, serial=1D588F6785C0DB
Set sample rate 7.680000 MHz
Set TX frequency 0.000000 MHz <- fails
TX ch:0 calibration failed, bw:5.000000MHz
Tx Calibration: MCU error 3 (SXR tune failed)
SR: 7.680 MHz
SR: 7.680 MHz
[PHY] [UE thread Synch] Running Initial Synch (mode 0)
On running examples found from internet should be like:
Connecting to device: LimeSDR Mini, media=USB 3.0, module=FT601, addr=24607:1027, serial=1D40ED5D833C8F
Reference clock 40.00 MHz
Set sample rate 7.680000 MHz
Set TX frequency 2680.000000 MHz <- working
RX LPF configured
Filter calibrated. Filter order-4th, filter bandwidth set to 5 MHz.Real pole 1st order filter set to 2.5 MHz. Preemphasis filter not active
TX LPF configured
Rx calibration finished
Tx calibration finished
SR: 7.680 MHz
SR: 7.680 MHz
Have tried .ini files with names:
LimeSDRMini.ini
LimeSDR_Mini_above_1p8GHz.ini
and also few very basic self generated using LimeGUI
Always the same result -> no TX freq set
Command I have been using is:
sudo ./lte-uesoftmodem.Rel14 -C 2655000000 -r 25 --ue-rxgain 115 --ue-txgain 90 --ue-scan-carrier --rf-config-file /home/oaiue/openairinterface5g/targets/ARCH/LMSSDR/LimeSDRMini.ini | tee UE10.log
Could someone guide me to right direction on this? Have run selfcheck/test succesfully for Mini and also verified using LimeGUI it works. Also I have two of these modules.
BR and thanks!
