From: Eyal Ilsar <redacted> If the value for the firmware configuration parameters BTC_STATIC_LEN_LE_BT and BTC_STATIC_LEN_LE_WLAN are not set the duty cycle between BT and WLAN is such that if BT (including BLE) is active WLAN gets 0 bandwidth. When tuning these parameters having a too high value for WLAN means that BLE performance degrades. The "sweet" point of roughly half of the maximal values was empirically found to achieve a balance between BLE and Wi-Fi coexistence performance.
