If I'm not mistaken, Google supports Find Information, maybe Microsoft’s Bing.
What exact functionality are you looking for?
Please check section Vol 3, part F, 3.4.3 Find Information in Bluetooth Core spec.
Take a look at WICED-Smart-SDK\Wiced-Smart\tier2\brcm\libraries\inc\additional_gatt_apis.h.
This is an optional patch. To use this API you should #include “additional_gatt_apis.h” in the source and add following line to the end of the makefile.mk.
