LimeSDR mini unable to transmit

Hi all,

I never managed to make my LimeSDR mini able to transmit, today I’m testing with OsmoTRX-lms and again, no good luck. I just realize that anytime I execute the “LimeQuickTest”, never pass the “RF Loopback”:

Please, could you help me ? Is there anything else I can try ?

Hi all,

I’ve just updated (LimeUitl --update) and now it works:
