Kalibrate-bladerf

[quirico0x00]

Hi all, I am trying to calibrate my blade rf 2.0 micro xa4 through the tool (kalibrate-bladerf) https://github.com/Nuand/kalibrate-bladeRF when I launch the tool after loading the correct fpga I get this result:

Code: Select all

root@RF:/Desktop/kalibrate-bladeRF/src# ./kal -s GSM900 
Actual filter bandwidth = 1500 kHz
rxvga1 = 0 dB
rxvga2 = 0 dB
error: bladeRF_source::set_gain
root@RF:/Desktop/kalibrate-bladeRF/src# ./kal -s DCS
Actual filter bandwidth = 1500 kHz
rxvga1 = 0 dB
rxvga2 = 0 dB
error: bladeRF_source::set_gain
root@RF:/Desktop/kalibrate-bladeRF/src# ./kal -s PCS
Actual filter bandwidth = 1500 kHz
rxvga1 = 0 dB
rxvga2 = 0 dB
error: bladeRF_source::set_gain
root@RF:/Desktop/kalibrate-bladeRF/src# ./kal -s EGSM
Actual filter bandwidth = 1500 kHz
rxvga1 = 0 dB
rxvga2 = 0 dB
error: bladeRF_source::set_gain
root@RF:/Desktop/kalibrate-bladeRF/src# ./kal -s GSM850
Actual filter bandwidth = 1500 kHz
rxvga1 = 0 dB
rxvga2 = 0 dB
error: bladeRF_source::set_gain

Can anyone help me solve this problem?

Regards

kalibrate relies on receiving signals from GSM basestations, which may not be readily around today. Can you please verify with gqrx that you are indeed seeing a GSM basestation?
