RE: IPv6 service UUID in advertising

Hi,

The specification states that this shall be included in the AD fields, and not in the SR fields. It might be that this works with some vendors, but it is highly recommended to use the method that is described by the IPSP GATT service specification:

4.1.3 Service UUID AD Type
When in a GAP Discoverable Mode for an initial connection to a Router, the Node shall include
the IP Support Service UUID defined in [2] in the Service UUIDs AD type field of the advertising
data.

The "shall" keyword is a requirement, while "should" keyword is optional when reading BT specs.

Best regards,

Håkon
