The nrf51422 couldn't able to discover the service.

[Namitha]

Hi,

I am using nrf51422  dk board using  sdk 12.3  and soft device  s130 in keil5 ide. In our project i am using nrf51422 board as central and other controller Bluetooth board (cc256 moda which is BLE  and classic Bluetooth) is used as peripheral. I am using the example program ble_app_uart (central )program for nrf 51 board by using the device name i am able to connect to the peripheral but is not discovering the service.I have changed the base uuid of the peripheral in the nrf51 central program. The base uuid of the peripheral is" 14839a42167340cf2339" .The problem here is we have 4 characteristics 

such as TX characteristic, TX credits characteristic, RX characteristic, RX credits characteristic which i have attached the uuid of these.Here the uuid of all the characteristic is different but here in the nordic uart program the uuid are same but only one 1 byte is changed and also there are 2 characteristic which are  tx and rx but here we have 4 with different uuid. Can you plz tell me how to use these 4 characteristic uuid and with different uuid .I am not getting how to discover the service. plz help me to resolve the issue

You know that nRF51 is not recommended for new BLE designs?

Thanks for the reply.

Yes i know that it wont support for new ble designs.since we have already started the development with this controller so we have started with this. can you tell me which one is the latest BLE designs so that which we will start development  which will support TI's Bluetooth and also this has  to support 4 characteristics with different uuid .so plz suggest me.

Did you remember to sd_ble_uuid_vs_add() those UUIDs before use?

Not that using four or more vendor specific uuids requires adjusting the vs_uuid_count parameter field for sd_ble_enable().

Thanks for replying.

Yes i remember to add base uuid to this sd_ble_uuid_vs_add  function.So here i have added base uuid. But i don't know to how to use and where to use  all the 4 characteristics in the program . can you plz tell me how to enable the cccd .plz tell me.
