Add custom 16bit UUIDs to custom 128bit service

[Nick_RA]

As the title... I have a custom 128bit service. I've added a bunch of characteristics using characteristic_add(), which end up as 128-bit characteristics according to nRF Connect even though they're 16 bit e.g. 0x1234

How can I make these 16bit?

Hi,

The value you passed, 

e.g. 0x1234

is the octets 12-13 of the 128-bit UUID.

Maybe some pictures will make my problem clearer: Both are screen captures from nRF Connect

(ignore the fact the characteristic numbers are actually different here)

This is what I have, which is as you say:

and this is what I want to match:

Hi,

So you somehow got it working here?

I have only seen this for Bluetooth SIG defined services/characteristics.

No, that was from another system, it is what I want to match.

Never mind, I eventually found something that works sd_ble_uuid_vs_add()
