I got a package of P115 today.

I have a couple of P100 since many years.

I manage to configure the first one when I selected the bluetooth-track.

Though, it never appeared in the list of units/devices.

I realized that I gave it the same name as another device, which may be the reason.

Anyway, after this no one of my four P115 can be configured.

I have followed the trouble shooting up and down several times, and I give up now.

I have seen other treads about this, but they never end up in a solution.
 

what to do??
