Bluetooth Autoconnect

[Jonchill]

I've connected to my Echo and Dot with Bluetooth on my phone and it works OK.

I have a couple of issues even with the phone sitting on the worktop only 3m away from my echo the music stream sometimes breaks up, is this Bluetooth or the Echo?

More annoying is that everytime I walk within range of the Echo or Dot it tries to autoconnect, is there a way of disabling auto connect so it will only manually connect?

Thanks

Jon
