Unable to start Service Discovery - Droid Eris #5

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. Trying to connect socket using UUID for UUIDHelper.RFCOMM_PROTOCOL_UUID
and UUIDHelper.SERIAL_PORT_PROTOCOL_UUID and giving this exception
2- On debugging found that below line is returning value as false;

  mService.getRemoteServiceChannel(mDevice.getAddress(), uuid16, this);
in class BluetoothSocket$SdpHelper

What is the expected output? What do you see instead?
It should get connected properly to the already paired device but not
connecting. Stack trace is like 

03-18 16:55:12.334: ERROR/ConnectionThread(5544): java.io.IOException:

Hello!
I have the same problem!

Could anyone tell me how to connect???
Discovery is no problem, but how do i connect? I can't find anything about 
that, and
I'm trying that now for more than 2 weeks!!

Just a short describtion would be enough, or only a small sample where a socket 
is
created and connected without threads or anything like that... please help 
me... I
really need this!

I got the same problem using the official android 2.1 API  on a Samsung Galaxy 
Spica
I5700 device. I described my problem here [1]. This seems to depend on the 
underlying
implmentation of bluez or something in the kernel. I wanted to try to establish 
the
connection using the NDK but I'm missing the nescecarry skills. So if some crack
could try this, I think many people would be very happy.

There is apparently a bug in the createRFcommSocketToServiceRecord() method, as 
a poster at StackOverflow noted:

droid

I tried out the suggested work around and now connection finally works for me 
on my HTC Droid Incredible.
