Hi there,

I'm trying to run kalibrate-bladeRF on my x40, i tried to run it over GSM850 and GSM900 but still no result shown, even i tried with -m. here are some info relate with my stuff

./kal -s GSM850 Actual filter bandwidth = 1500 kHz rxvga1 = 20 dB rxvga2 = 30 dB kal: Scanning for GSM-850 base stations. GSM-850: host@host:~/kalibrate-bladeRF/src$ ./kal -s GSM900 Actual filter bandwidth = 1500 kHz rxvga1 = 20 dB rxvga2 = 30 dB kal: Scanning for GSM-900 base stations. GSM-900: bladeRF> version

thank you for any help.

2G networks have become quite rare in recent years. It might be there are no GSM signals in those bands anymore.

thank you for your reply Robert. I really appreciate it. regrding my issue, at first it was showing me some result both on GSM850 and GSM900 but suddenly it becomes no result each time i run it. and secondly, when i'm trying to run grgsm scanner, it gave me
