Scannig Remote APs WIFI spectrum within CAPSMAN

Hello,

I am using 6.40.5 for devices. After activating capsman, I can not scan wifi spectrum of APs. Does not allow me, states it is being used. Is There a feature in CAPSMAN that will allow me scan remote AP wifi specturum to find the best channel. I have read several discussion in the forum, but I could not decipher them.

Any help much appreciated.
