https://devzone.nordicsemi.com/f/nordic-q-a/125815/question-about-nrf9151-s-at-xmipirffectrl-command-s-frequency-parameterHi Nordic support: Our project uses the nRF9151 and QM13545 MIPI RF SWITCH. We have a question about AT%XMIPIRFFECTRL command&#39;s frequency: If the frequency switching point of the RF switch is set in the middle of a band, can it work normally?
