Anker selfie stick loosese bluetooth connection

Hi all,

My new Anker selfie stick keeps losing its connection after it goes to sleep.

I pair the device, which goes well.

I can also use it like normal.

But when the selfie stick goes to sleep and when I press the wake/take photo button again it doesn't re-connect to my phone.

I've tried it with an iPhone 5 running iOS 9.3.5 and there it worked.

But after upgrading that phone to iOS 10.0.2 it also didn't work.

My details are:

iPhone 7

iOS 10.0.2

Anker Selfie Stick model: A7134

I've re-paired the device and did a Reset of Network settings. But no success.

Any suggestions?
