Matthias,
Thank you for the information and the link.
Does this also apply to non-LE applications?

Hi Chip
The client of an LE HID Device (HID-over-GATT), the HID Host, does not
need to implement or advertise any services.
The HID Device can reconnect and send new notifications if needed.
Feel free to browse the specification:

Hello again,
I realize that this is an Apple specific list, but everyone here
seems friendly enough that I think I can ask this more general
question without being flamed...
Can someone please confirm or correct my understanding about making a
connection with BT?
As I understand it, for two devices to be able to connect they must
both have the same Service UUID (and Service Class UUID).
Say, for example, a BT keyboard. Keyboards are usually handled under
the HID group, so the keyboard must advertise that it supports HID
and a keyboard. Likewise, on the other side of the connection, the
other device needs to also have a identical UUID so that the two
devices know that they can 'talk' on the same "port".
Did I read this right?
I presume there's no way around this requirement if the device that
you want to connect the keyboard to does not advertise that capability...
Thank you,
