A problem in BLE service discovery

[alireza sadeghpour]

Hi,

I am developing a product based on  SDK v15.3.0 and SoftDevice v6.1.1. my product acts as a BLE central device.

On the peripheral side, is an iOS application which contains a service with "fb349b5f8000008000100000fdff0000" UUID. "fb349b5f800000800010000000000000" is an standard base uuid and when i trye to add this uuid with "sd_ble_uuid_vs_add" function, as uuid_type i get '1' which means that this uuid could not be added as custom 128-bit base uuid.

Then I try to register {uuid: 0xFFFD, UUID_Type: 1} with "ble_db_discovery_evt_register" function, to search for "fb349b5f8000008000100000fdff0000" service in iOS gatt table.

during service discovery, Softdevice sends a "FindByTypeValueRequest" with value 0xFDFF in order to find the service in the iOS gatt table, but it receives "FindByTypeValueRespnse" with "attribute not found" error code.

Now can anyone give me a solution, to search for a service with "fb349b5f8000008000100000fdff0000" uuid in the iOS gatt table?

As i said, registering "fb349b5f8000008000100000fdff0000"  as base uuid is not possible in the sofrdevice, and searching with 16-bit uuid "fdff" could n't find the service in the peripheral gatt table.

Thanks

Just let me make the problem clear,

- There is a service with "fb349b5f8000008000100000fdff0000" UUID in the GATT server (which is created by iOS application in an iPhone device)

- When I want register "fb349b5f800000800010000000000000" 128-bit uuid with sd_ble_uuid_vs_add function, as uuid.type i get 1(but with registering another 128-bit uuid i get 2 which means 128-bit uuid is registered successfully)

With searching with 16-bit uuid "FFFD" i could not find service in the client services, and i can not search for 128-bit version "fb349b5f8000008000100000fdff0000" because i can't register "fb349b5f800000800010000000000000" uuid with sd_ble_uuid_vs_add  function.

Now I want to know there is any way to discover "fb349b5f8000008000100000fdff0000" service and its characteristics in the client?

P.S

In  you can see that softdevice sends a FindByTypeRequest with 16-bit version of the uuid. how can I ask from softdevice to send this request with fb349b5f8000008000100000fdff0000 uuid?
