Any ideas on what might be causing it tom?

As soon as I use my iPhone SE or my 7plus it fine, but on all the android device I own it does the same thing.

The only thing I can see that I have that probably different is the anti-theft/privacy mode key is enabled.
Unless it’s my Bluetooth unit itself??
At a complete loss to figure it out, it would be easy to explain if it was just occurring on one device.

When it tries to connect/disconnect I hear ALPConnect attempt to connect, then it flashes red then off (cycle repeats until it finally connects)
Could this be an error
