Excluding service from SimpleBlePeripheral project. cc2541

kumar singh

Hi,

I am using SimpleBlePeripheral example project. This example project includes different profile services and multiple characteristics. As there are multiple services and different characteristics used, it takes around 5sec to discover these services in android phone. Can anyone please suggest if it will create problem if i reduce unnecessary services and characteristics or all are mandatory? I am using just simpleGATTprofile for all my communication.

thanks

Hi Fredrik,
i had referred to SW developers guide which explains how to create service and defining characteristics. This i have understood. What i want is to reduce these unnecessary services and characteristics used in order to reduce the discovery time. If number of services and characteristics are more then it takes more time to discover in phone. So for this only i had asked if i can reduce the service. i am not using SW service. Mostly i am using simpleGATTprofile for communicating and not using other profiles.
thanks

In simpleBLEPeripheral.c just search "SimpleProfile_AddService( GATT_ALL_SERVICES );" and add comments if you don't want it.
I don't know if that is you want..

Or you want remove Device information service for exemple ?
anyway, just search "SimpleProfile_AddService( GATT_ALL_SERVICES );" and you will find DevInfo_AddService, GATTServApp_AddService, GGS_AddService just at the top.

I hope that what you want.

Ya thanks. This is what i wanted to know. will test and see if commenting unnecessary services reduce the discovering time.
By the way can you please tell me how can i maintain connection for long time. I want peripheral not to disconnect anytime. in phone i am struggling to continue connection in background when my app closes. If i can succeed then later i want peripheral should not get disconnected in any moment.

You have just to manage your BLE Service.
You can find specific tutorial on Android developer.
Look for Android Beacon Library too : altbeacon.github.io/android-beacon-library

Best regards,

Will check it. Have you been successful in maintaining connection in background when app closes? the link shared by you is mostly for broadcast advertisement and not for peripheral.
