use 52832 to recognize three level UUID

I use 52832 as a center to recognize a device which have three level UUID,but I only read the second UUID.how can I to read the third UUID

Hi,

Are you using the data base discovery module in our SDK? if so which SDK? Have you registered all the UUID's with the module?

Regardless, if you are using vendor specific UUID's you need to register these with the SD, sd_ble_uuid_vs_add.

I use this funtion to add my own UUID,so I found the first and second UUID.but I can't found the third UUID.

How are you initializing the services and characteristics on the peer? Are they all using the nus_base_UUID? if not you need to add more vendor specific UUID's

[NORDIC_SUR]

I only init the main service UUID.but I found the last four byte of all second 128bit UUID is the same."0x43,0x53,0x53,0x49".you mean I need to init all128bit  characteristics UUID?and  how to add these 128bit UUID.and I have another question,there have 3 level UUID,which is services UUID,which is characteristics UUID?

If the service and characteristics have different 128 bit base UUID's you need to add them all. If they use the same base UUID, but you only change 16 bits in the "middle", you only need to add 1 vendor specific UUID. The last bytes will not change.

To understand how this works you could look to the uart example in the sdk that only use one vendor specific UUID. And you can look at the ANCS example that is using multiple vendor specific UUID's.

I found only the peripheral have the ancs example.I will test it,thank you!

That is correct, it's a peripheral example that is a gatt client and uses our discovery module.
