My Config : Bluetooth USB Key : Belkin USB Key F8T013XX1 (that is what is written on the key) with Belkin WIDCOMM driver version 5.1.0.3300
Windows XP. Dell Dimension 9200.
I, with pain succeded in connecting to my 2 wiimotes.
I ran my API that connected to both and it worked quite well.
The day after, it worked again.
So I wanted to test that I really had control over the whole process of bluetooth connection : big mistake !
Good Connection is indicated when the icons show a green arrow.
I disconnected the two wiimotes from bluetooth (deactivated the peripheral).
I removed the battery from one to be sure there was no bad interference.
And now, in the connection process, the green arrow appears only for a fraction of a second while selecting the service. The tray icon remains green a little longer, but this changes nothing.
Yes I tried to keep pressing 1+2, with no success.
I tried reinstalling the drivers with no success.
The batteries are Full.
And worst of all, I have now an info bubble that pops up over the tray icon 10sec after the failed process that says :
Personnal Bluetooth Code Mandatory.
The peripheral nintendo RVL-CNT-01 tries to connect to this computer. Click here to autorize the connection. To refuse, discard this invite.
If I click on the bubble, a box appears. (here the french version)

It says "they have to be paired" blabla , OK/CANCEL/HELP...
Since I have no code, that leads me nowhere.
It really looks like over the count of connections, it was getting worse and worse. I mean : harder and harder to connect. I mean : the old one was harder to connect, then both, then the first got impossible, then the second one (Just an impression in the chaos).
Any Idea ?
