Am I right that the added BT device disappears after you hit disconnect?
Please clarify bullet 4.

At step 4 device is still in the bt devices list but not visible if you go into 
add devices.
I observe that successfull connects have the device still shown in the bt 
connect screen. 
The device itself is still discoverable and connectable but the phone Amarino 
app will not connect.

- Which BT module do you have?

- Can you verify if disconnect works properly, or does it just not disconnect.

- Is there a indicator light on your BT module which tells you the state of 
your connection?

Using SURE BT module, cannot easily tell at the BT module if disconnect worked 
properly. A couple of undocumented pins change voltage at connect and do not 
change back - so that may indicate disconnect not working.

Assume it is an Amarino fault because resetting at phone end fixes issue.

I note you have another issue open where disconnect does not work - also HTC 
Desire!

Indeed, it seems to be the same issue.
Could you try the latest Amarino version 0.5 and check if your issue is still 
remain.

@jgcrouchley: if version 0.5 doesn't fix the issue, could you please send the 
log from your phone to me right after your tried to disconnect and reconnect.

You could use "SendLog" which is downloadable for free on the Android market or 
the Android SDK tool DDMS to get access to your phones log (logcat).

Log sent to bonifaz@media.mit.edu.

I tried connecting to the BT device with my PC - no problems connect, send 
data, disconnect repeatedly. By observing I note that pin 28 goes high when 
connected and pin 30 goes low. The PC appears to disconnect properly.
Amarino does not disconnect properly - the pins stay in the connect state.

Version 0.5 installed

Sent the phone log.

My step :
1. Using test event, connect all is OK
2. Disconnect
3. attempt to connect again (Device IS present on device screen)
4. The connect button change to gray and say Connecting and hang (return active 
after screen lock/unlock)
5. Stop bluetooth on phone
6. kill Amarino and restart
7. connect - all is fine again

Note : Sparkfun Bluetooth Mate (BT-Serial-Bridge)

Following findings so far.

HTC Desire disconnects fine, but a reconnect triggers an error: Cleaning up 
failed UUID channel lookup

Various people have reported that the HTC Desire has issues connecting to SPP 
Bluetooth devices. I am not sure if I can find a workaround for it, since it 
seems to be a HTC Desire firmware bug.

But as I said, hopefully I find a solution for it anyway. It is just not simple 
without a HTC Desire device in my hands.

I uploaded already a newer version of Amarino (0.52) maybe this does the job 
already.

Here is the corresponding issue within the Android open source project.

http://code.google.com/p/android/issues/detail?id=8382

http://groups.google.com/group/android-developers/browse_thread/thread/e8c16aff1
10ebbd5

and other people having the same issue which is not Amarino related, but a bug 
in HTC Desires Bluetooth implementation. I think they will fix it when Android 
2.2 will be shipped to the Desire.



I tried the workaround calling the undocumented method mentionend in that 
discussion. It is implemented in Amarino v.0.52
