9.13 Bluetooth Coexistence

The DA16200 provides a Bluetooth coexistence function to properly coordinate the use of the

2.4 GHz Wi-Fi radio with external devices that also use a 2.4 GHz radio such as Bluetooth.

9.13.1

Interface Configuration

The following three pins can be set in pin multiplexing:

● BT_sig0 (oWlanAct)

○ Output - indicates WLAN is currently active

● BT_sig1 (iBtAct)

○ Input - indicates BT/BLE is currently active

● BT_sig2 (iBTPri)

○ Input (optional) - indicates BT/BLE has higher priority than WLAN

A variety of configuration settings are available, including active high/low, manual force mode, use

status of the optional iBTPri function, and whether to switch oWlanAct to active in the event of

TX/RX/TRX.

Operation Scenario

Bluetooth coexistence can be enabled/disabled through configuration registers. The activation

scenarios based on the status of each pin are described below:

● BT_sig0 (oWlanAct)

○ When asserted, external BT/BLE is expected to stop occupying RF

● BT_sig1 (iBtAct)

○ When asserted, DA16200 stops occupying RF

● BT_sig2 (iBTPri)

○ Optional and thus may not be used

○ If it is used and DA16200’s iBtAct = Active while iBTPri = Non-Active, DA16200 may ignore
