[Bug]: IPeripheral's connection state is not updated after .Scan() running again

Do you have a good business case for this? This potential fix may seem "easy" here, but it definitely is not?

• Most peripherals stop advertising when they have connections
• Rescanning with the same cb manager is not recommended as any good practice

According to the Apple guide, scanning should be active only when it is really needed to save battery power.

business case:
Once we have found all of our expected devices, we stop scanning.
But, if we want to add another device to the device list, we run the scan again.

Are you actually connected to the devices while running a scan though?

No response from user.

You can't keep a reference to an unconnected device and then run a scan. iOS emits new peripheral.
