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.
