and none of that was what he asked. He asked if he could hide a service during advertising, which you can by .. err .. not advertising it and have it discovered at connection which you do by having the service. No need to add or remove things, or use authorization or in fact do anything at all. Just choose the UUIDs you put in the ad packet. Done.

To add or remove services from the GATT database, you need to restart the SoftDevice, so you can not do this during a connection. You can, however, change what characteristics can be read/written during a connection by using Authorization.

Many thanks! Could you provide me an example of doing it? Is it possible to add or remove services during connection?

Yes - don't put it in the advertising packet as an advertised service. You'll then only discover it after connection
