Abstract
Aspects of the invention may comprise managing operations of BLE interfaces and/or other radio interfaces in a wireless device to mitigate interference to communication via the BLE interfaces by the other radio interfaces. Operating parameters may be communicated between the BLE interfaces and the other radio interfaces to enable mitigating the interference to the BLE interfaces, and at least some of the BLE interfaces and/or the other radio interfaces may be configured based on the communicated operating parameters. The operating parameters may comprise adaptive frequency hopping (AFH) maps that may be adjusted to prevent use of common and/or used channels. The communication device may detect energy associated with BLE communication via scan of all or some of channels used for BLE communication. BLE communication may be predicted based on monitoring of frequency bands used during BLE communication, and/or monitoring of events that may trigger and/or occur during BLE communication.
