8.13 Bluetooth Coexistence
DA16200MOD provides the Bluetooth coexistence function to be properly aligned with external
devices activated at 2.4 GHz.
8.13.1 Interface Configuration
The following three pins can be set in pin multiplexing:
● BT_sig0 (oWlanAct)
○ It indicates that Output, WLAN is currently active
● BT_sig1 (iBtAct)
○ It indicates that Input, BT/BLE is currently active
● BT_sig2 (iBTPri)
○ It indicates that Input (Optional), BT/BLE has a higher priority
A variety of configurable settings are available, including active high/low, manual force mode, use
status of the optional iBTPri function, and whether or not to switch oWlanAct to Active in the event of
TX/RX/TRX.

8.13.2 Operation Scenario
The Bluetooth coexistence can be switched on/off by the configurable register, and 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, DA16200MOD stops occupying RF
● BT_sig2 (iBTPri)
○ It is optional and thus may not be used
