This commit extends the pattern matching capabilities of advertisement
monitors with matching for service UUIDs. This functionality was lost
with bc2ab4b (see #652) and not added with b0656c2.

Hi,

I submitted below patch in August. I'm interested in getting it merged,
but I have not received any feedback on it.

If there are any issues with this patch, please let me know. I'm happy
to work on it if more iteration is required.

Best,
Markus
