Anyone have Lego NXT unit? I'm trying to connect it with Spica over BT but no success.

I tried three free apps: MINDdroid, NXT Simple Remote and NXT Remote Control.

Spica finds NXT, but says "paired but not connected" and when running app, the app says that device is not connected or even force closes!

NXT finds Spica, three lines are available to connect, but each line says "line is busy".

I would like to control robots with Spica!!

Any solutions?

Forgot to mention:
- I use 2.1 default Android on Spica.
- Win 7 64 bit connects over BT with NXT normally and i can control motors.
- Here is nice NXT Bluetooth Developer Kit if any dev can find problem: LINK.

If anyone using different software and controlling NXT works please tell here.
