Fixes #754

Add information / tips to help with:
* Connection issues to multiple devices
* Pass more parameters to notify callback function

This seems like two unrelated problems, so I would expect two separate sections in the docs.

• Pass more parameters to notify callback function

I'm wondering if we should fix this in code instead of "fixing" it in documentation. See my previous comment at #754 (comment).

I opened #759 to discuss this separately.

My goal was not to "fix" here, but to possibly save someone the hours and hours this cost me until the better action, something like #759 is complete.

It's not very clear, are you interested in improving the docs here or do you want to leave this not addresses and just fix the API to handle this? Your response is not very clear and easy to interpret to action(s).

OK, I will try again.

These are two unrelated issues, so combining them into one troubleshooting section seems like it would make it harder to find the answer for one or the other.

• Connection issues to multiple devices

There is no debate about this issue. Having a troubleshooting section that explains that you should use a separate BleakScanner to scan first and then stop scanning before attempting to connect when you have multiple devices sounds like a good idea to me. This applies to multiple devices in general, not just ones with the same service uuids.

• Pass more parameters to notify callback function

I don't have a strong opinion one way or the other if we include this now or wait to see what the resolution of #759 is. But if we include it now, it should be a separate section from the scanning issue.

Thanks for updating. I just have a few suggestions.
