Android Question java.io.IOException: unable to start service discovery

[3394509365]

Hello, I'm starting to make an app where I need bluetooth. I started seguento but your tutorial is on what is called Bluetoohh is on what is called a serial ... and transferring the files, I get the following error "
java.io.IOException: unable to start service discovery "

Basically, the program gets to the point that makes me choose which device to connect, but never connects to any device and gives me that error message.

I have read several answers on the forum but I have not solved the problem and I do not understand what it is.

Does anyone know what you do in this case?

thanks

are you connecting two Android devices?

Yes Samsung galaxy e Samsung ace plus. But also samsung vs pc windows. The error is again.
There is a solution?

Start with running this example as is: Android Bluetooth / BluetoothAdmin Tutorial

Do you get any error?

 

[3394509365]

I started with just this

 

[Erel]

Can you post the full error message from the logs (with this example) ?

 

[3394509365]

I have attached the log where is described the error.

It might be a hardware problem. When do you get this error? When you try to connect?

I ordered on the internet a new bluetooth dongle so I can see if the problem is the computer. However, the 'error' t I even between phones.
I found that if I try to connect the phone on which I have the 'app to an old samsung phone no smartphone' s not me by mistake and it connects perfectly.

we feel just get the new key. thanks

Mrs.
I have a tablet Sansumg Galaxy 10.1 and a phone Sansumg SII and a DELL PC. None of them work. The error message is java.io.IOException: Unable to start Service Discovery
I am disapointed with WiFi and BT communications. Why are there so problems?
Thanks,
Galbas

Have you tested the Chat example on the two Android devices?

 

[Galbas]

Yes, but sometimes my phone no recognize other bluetooth devices. Do you think can be a hardware problem?

 

[Erel]

What do you mean with 'recognize'? Not all Bluetooth devices listen to incoming SPP connections (on the default address).
