iOS.Device: update device name upon connecting to peripheral

[janusw]

This is a second attempt to fix #541 and #703, following the first attempt in PR #711, which apparently was unsuccessful.

Hi @janusw , thank you for your quick action. Unfortunately it gives an error, when I try to install the nuget.
I can see it in the nuget manager but when I try to update or install, it fails. Bellow is some of the log:

Sounds like the nupkg is not found. Did you set up a local package source that contains the nupkg downloaded from this PR?

@janusw I follow the same steps as with previous PR. with the previous one I can install OK, although it says already exists which is very strange.

I also try a complete clean of the project (bin, obj...)

This is what I get now when I install the old PR

All packages and projects are compatible with .NETStandard,Version=v2.1.
Package 'Plugin.BLE.3.0.0-rc.1-2-ge03790e' already exists in project 'EggRider'
Committing restore...

@janusw I feel is some bug with VS on mac...
I manually copied the nuget to /usr/local/share/dotnet/library-packs and it installed.

Successfully uninstalled 'Plugin.BLE 3.0.0-rc.1-2-ge03790e' from EggRider.iOS
Successfully installed 'Plugin.BLE 3.1.0-beta.1-5-gf61e598' to EggRider.iOS

The problem become even worse now. The name for connected device is not picked up even after turning on/off the bluetooth, which normally solved this issue.

Device name is: UpdC1
StartScan
Advertised Name returns -> UpdC1
ConnectToKnownDeviceAsync -> Connected device name returns -> DeviceC1 (the service uuid seems to be correct)

Wouldn't be the first one 🙈

👍

Well, alright. Then there is indeed a good reason why that line was commented out 😆. Anyway, it was worth a try. Thanks for testing.

I guess @GerryWilko is right with his assessment in #541 that this is a bug in CoreBluetooth. Maybe someone should report it to Apple directly ...
