It is probably bonded with the phone. If it is bonded, the phone will try to reconnect if it looses the connection. Go to bluetooth settings on your iphone and find the ANCS device in the list. Click on the "i" and choose "forget this device"

Lightblue + ANCS is a bit of a pain. Once iOS decides to auto-connect, Lightblue and most of the other similar tools become useless because they only know how to connect to devices that are advertising. Sometimes you can race the auto-connect by cycling bluetooth on and off, but most of the time this fails.

Would be nice if there was a way for apps like lightblue to talk to an already connected device.

This is a normal behaviour... As soon as you use ANCS, you have to pair your device with your iPhone. If you disable the bluetooth on your iPhone, your device lost the connection and start with the advertising procedure again. As soon as you re-enable bluetooth on your phone, it re-connects automatically. If you build your own iOS app, you have to manage the connection in a special way. You have to work with core-bluetooth which handles the connection with paired devices.
