Hi Sathish, > Enable LL Privacy using mgmt set_privacy command. The privacy > value 0x03 is used here to enable LL Privacy. > Still to use LL Privacy controller support is must. that is not what I meant. And it is also misleading since Set Privacy is enabling RPA usage and not RPA resolution. So what I meant was using the Set Experimental Features mgmt command to enable usage of RPA resolution in the controller. Regards Marcel
