Hi,

Stack version used : 3.02.00.00.

In my project i want to add /delete a service dynamically during the runtime based on the event.

Please suggest some idea how to do this?. with available API like GATTServApp_DelService and GATTServApp_AddService .

Thanks and Regards,

Hi Jayachandran,

You would want to look into using the service changed characteristic and read through BLE Spec 4.2 Vol 3, Part G section 7.1 as well as our documentation below:
dev.ti.com/.../gatt.html

As far as de-registering and deleting services you can reference the API documentation. dev.ti.com/.../group___g_a_t_t_serv_app.html

I'm not sure we have an explicit example of this at this time.

Hi Evan,
Thanks For reply.
For my understanding for remove/De-register a service i can call the API GATTServApp_DeregisterService( uint16 handle, gattAttribute_t **p2pAttrs );
In this i can pass handle of the service, but how i can pass "p2pAttrs"..
Which variable i need pass here ?

Jayachandran,

p2pAttrs is the array of attribute records that were registers initially through GATTServApp_RegisterService(). It's basically a struct of gattAttribute_t: dev.ti.com/.../group___a_t_t___g_a_t_t___structs.html
