Joe,

I'm curious about your approach. Can you share a code snippet? Are you saying that the descriptor name cannot be read at all in Anrdoid/iOS, or is it just when using the Nordic app?

I tried to p_char_user_desc pointed to a string, but not Android nRF Mcp nor iOS Lightblue shows that characteristic name.

Two comments on this:

The advertisement data Service UUIDs are supported by the SoftDevice and you can include those when calling sd_ble_gap_adv_data_set(), you would need to use one of the BLE_GAP_AD_TYPE_xxBIT_SERVICE_UUID adv data types in the buffer provided.
Although you cannot name a service, you can associate a UTF-8 string with a characteristic, which is provided to the sd_ble_gatts_characteristic_add() via theses fields in ble_gatts_char_md_t:

p_char_user_desc char_user_desc_max_size char_user_desc_size

Yes, that is correct. I'm not aware of any way you can get anything else than unknown there for custom services.

OS when founds a service, in NSDictionary write kCBAdvDataServiceUUIDs as unknown + .

So, "Unknown" is, at this point, from iOS and not from nRF51822 broadcasted data.

Is it correct ?

There isn't a name attached to any BLE service, so identifying a service by name isn't really possible in any standardized way, without the Central reading the name based on UUID from somewhere else.
