Bluetooth 4.0

[mrossen]

Hi,

I have made an app with uses the serial library.

My app connects to my bluetooth device without any problem.

When I moving out of range it disconnects as it should, and when I come into range it connects as it should again.

This works fine on all my devices, except my HTC One X.

On the One X the device will not connect automaticaly when I come into range again.

The One X is the only phone I have with bluetooth 4.0, so I think this can be the problem.

Is there anyone there have a problem similay to this, or maybe have a clue to what can cause the problem.

I haven't tested HTC One Bluetooth. However at least with older HTC devices (such as HTC Desire) the Bluetooth was very unreliable.

You should check the unfiltered logs and see if there are any related messages.

Hi Erel,

I have tested with HTC Desire, HTC Desire HD, HTC Sensation and HTC Wildfire.
They all work perfect.

I also have the same problem with my Samsung Tab 10.1. But this is a tab so I dont know if there is a difference here.

What do I have to look for in the unfiltered log?
Thanks, Mogens

How did you implement the reconnection?

 

[mrossen]

It runs in the backgound in a service.

and with serial.listen

If you want to see the code I can post it later today. I am not behind my own computer.

So the other side tries to connect to it, right?

You should check for messages related to Bluetooth.
In version 1.90 I added support for B4A-Bridge over Bluetooth.
Some device work perfectly (including Galaxy Tab 10'). Others were not stable. If I remember correctly there are more than 700 reported bugs in Android about Bluetooth.

Yes, you are correct. It is my bluetooth device there is "master"

Thanks, I will try to look in the log later.
