How can a customer modify the default channel map settings (i.e. filter some Tx channels) for BT classic? Our customer use WiCED6.4.

There are related APIs- BTM_SetAfhChannelAssessment() and BTM_SetAfhChannels(). However, there is issue of availability in different version. This problem is further tracked in a technical case, therefore, closing this thread.

Hi MaSc_1495886​,

There is no way to change the channel map settings for BR EDR. You can select the advertising channels for BLE in wiced_bt_cfg.c.

If there is no way to modify the channel map, it there a way to tune or optimize the AFH algorithm? Or to set some channels on a kind of blacklist? We have the CYW20706 working in an environment where an other non standard 2.4GHz device is working and the current AFH algo doesn't recognize this signal and rate the channels busy.
