Hi, 

Do you have the list of all the services you want to discover ? (the UUID list) 

If you do you can just register the service to be discovered, the same as it's done inside ble_nus_c_init(). 

If you don't know the services, and you want to make something like the nRFConnect app. It's more difficult and requires you do a little bit of work to make the discovery service generic.

i know all the services.and their corresponding UUIDs.now i want to only connect with these services and want to get these services  data on nordic .kindly explain me in details how can i do this.currently i am modifying nordic uart_c example from sdk15

Hi,

I would suggest you to study the ble_app_uart and ble_app_uart_c to see how it works. I can try to answer your questions or have a look if you have an issue. Try to add one more proprietary service into ble_app_uart and then modify ble_app_uart_c to discover both service (uart and your own ). After that it should be easy to discover all the services on your 3rd party peripheral.

This code will discover all services of the device https://github.com/I-SYST/EHAL/blob/master/ARM/Nordic/src/ble_dev.cpp

Use usage example here https://github.com/I-SYST/EHAL/blob/master/ARM/Nordic/exemples/UartBleCentralDemo.cpp
