How to manual disconnect from BLE UART server

Ok so BLE task 3 is already in progress should be interpreted as disconnect, right ;-)

And the guess that the 1st disconnect is fired, but takes some time to process, so that the 2nd disconnect result in "BLE task 3 ......progress" seems plausible.

But I'm not out of the woods yet.

When I start the code I get this, as before, disconnects after some "overshoot".
The UART server recognises the disconnect after the last outputline, stops sending notification, start advertising again for a new connection.

When I re-upload the code for a 2nd time, the UART server recognises the reconnect and starts sending data, but the BangJS does not process the notifications and displays no output, and after 10 secs or so I get an "Uncaught error". My server never gets a disconnect, so keeps sending data, forever.....

My intention was to process the code with a setInterval every minute or so, but with the current behaviour that seems problematic.

Hmmmmm, problems, problems.

Thanks for your help though, if you have any other suggestions, yes please.
