GATT Client on blecent + AFH

Hello! Let's start talking about what I'm trying to do. The Bluetooth protocol have a feature called AFH (adaptative frequency hopping) that monitors the quality of each Bluetooth channel and include or exclude them of a channel map for the frequency hopping. I'm trying to reproduce this with a link...
