3.10 Bluetooth Radio Interface
The SR/AI presents an integrated ceramic antenna.
The SR/AP presents no integrated ceramic antenna whereas provides a 50
RF
interface.
It is highly recommended that you follow the design rule given in the Stollmann Application Note on
Antenna design [4].
3.11 WLAN Coexistence Interface
4
For implementing WLAN Coexistence with CSR’s Wi-Fi solution the Unity 3e scheme could be
implemented on request. Usage of signal BT_PER is not necessary at the moment.

If this interface is not used, these signals should be left unconnected.
If your application needs to use these signals, ask Stollmann for support.
