Never touch a running system Hope you find the solution. Don't want to start this all over againok, there must be really something weird here that must be done in a PRECISE sequence... and then leave everything as it is.
I found in the one that WAS working that it was paired only in windows, but the windows pc wasn't present in the pandora paired devices... so I paired... now it disconnects after a minute... I deleted the pairing from the pandora... nothing changed...
I'll start again all the tests... at least now I know that is possible to make it work with Bluesoleil...
