may solve this. The commit log is: "Add firmware for BCM4325"

If there was no firmware in the kernel to support this before, then it obviously would cause problems.

I guess I'll have to see if I can build android from source and install it on my phone :-(

This thread over at Google Groups (android-developers) is also interesting: ' Is Google working on the Bluetooth bug? Any estimated date of completion? '

Answer 3

I found this exact problem happens when one of the devices has the Bluetooth turned off.

Answer 4

Ok, solved it.

The solution is to update the firmware on the phone. I now have: PDA: I570EXXJE1 PHONE: i570EXXJD1 CSC: I570EOXEJE1

and bluetooth spp worked 'out of the box'.

Look at http://samsung-firmwares.com for both the latest firmware as well as programs to flash the phone (odin) and details/tutorials.

Answer 5

I got this information from the gps-sport forum. Not sure what to do with it though...

Cross posting this entry from the software category. The thread over there deals with the Zephyr HxM as a secondary issue - meaning it mightn't be easy to find...

A fix to the bluetooth connection problem

Hi

If this problem still is not resolved, the code below describes how to make the connection work with Android 2.1 (Tested on HTC Desire). Just replace "00:07:80:89:EE:EB" with the MAC of your HXM to make it connect. After the connection is successful, a regular method with input = socket.getInputStream() can be used.

BluetoothDevice hxm = BluetoothAdapter.getDefaultAdapter().getRemoteDevice("00:07:80:89:EE:EB");
Method m = hxm.getClass().getMethod("createRfcommSocket", new Class[]{int.class});
socket = (BluetoothSocket)m.invoke(hxm, Integer.valueOf(1));
socket.connect();

Hope the fix will be out very soon =)
