Before connecting the Bluetooth SPP for sure. Default UUID is not always correct for SPP.

Which device are you trying to connect to?

From noname CN device Android 4.0.3 to be connecting to LG P500 with factory ROM Android v.2.3. as in my signature.
Also tried my old app without BluethoothAdmin, old lib - the same result. But i have never tried this LG before for BT - no idea how should be.
Aim is to develop SPP connection. How to be sure that SPP is supported ?

But if to try serial1.Connect3(Settings.connectedDevice.Mac, 1) - LG is connected as headset OK ! (but if to try to send a byte - disconnected)

Try to connect to a different port. It is also worth trying ConnectInsecure.

Other ports give
java.io.IOException: [JSR82] connect: Connection is not created (failed or aborted).
How to be sure in UUID ? I guess, universal way is to get all UUIDs and select among available.

 

[Erel]

Which ports have you tried to connect to? You do not need to know the UUID if you connect to a port directly. Try to connect to ports 1 to 10.

Make sure to call ListenInsecure / ConnectInsecure.

 

[Erel]

Now that I think about it, are you sure that you called Serial.Listen on the other device before trying to connect to?

You are right, listening must be already on the other side.
But strange that this started to work with HyperTerminal under Win7 Bluetooth notebook, but does not work, if another side is Android with a Blutooth server from Play Market, listening the connection.
