grgsm no decoding on raspberry pi 3

[jbarea]

Hello, i installed without issues grgsm on my raspberry pi as you described. I launch grgsm_livemon and i got the window with the frequency slider and spectrograph showing signals in the band. The problem i'm experiencing is that when i select a known frequency for a base station, the terminal should be showing the data stream but instead it remains silent. I know there should be data in the screen because when i change to my laptop and execute grgsm_livemon on the ubuntu installation there, data begins flowing and i can then work with it with wireshark, etc..

What could be causing this on the raspberry?. Building process went without errors when i followed the installation steps?. Thanks in advance!

I have a raspberry pi 4b (Rasbian 32 bit). GR-GSM decoding works, but data packets are being dropped all the time. Apparently there is not enough CPU power. It may be necessary to install a 64 bit system. Raspberry 3 is less powerful. Maybe this is the problem?
