Bluetooth Connectivity

Wed Sep 21, 2005 1:45 pm

Hi,

we are in search of some component where whe would have the abbility for listening to several bluetooth headphones with one device.
Situation:
- We have a IPaq with BT.
- We have serveral BT Headphones

Now we want to connect these headphones to this one device.
Could this be possible with your upcoming component?
And approximatly when would this component be released?

kind regards,
Steve

In other words, is it going to be possible to program multicast, unidirectional?

Also, will the iPaq 4150 be supported?
This one is running the BT-PPC Version 1.6.0 Build 0600 from broadcom.

Yes, it will be possible to let multiple devices connect to a service. However, there will be no support for audio connections supplied with BlueTools. I think audio connections run over RFCOMM, so it should be possible to implement this.

The 1.6.0 stack from Broadcom will be supported.

How do you mean RFCOMM?
We are using HP bluetooth headphones.

RFCOMM is a transport protocol in the bluetooth stack. That is nothing get in contact with in BlueTools. It just means that you need to implement the communication with the headset as if it was connected to a serial port (communication is done through a System.IO.Stream).

So by using our bluetools in conjuction with system.IO.stream on the serial port it should be possible?
Is this correct?

regards,

PS: there is also a thread running from me on the GPS Tools section, could you have a look also.
Thanks verry much

You won't have to get in contact with a serial port. The communication is just similiar to serial port communication, meaning that you have an outgoing and incoming stream. Basically, it would look like this (in C#):

Code: Select all

protected override void OnClientConnected(Session session)
{
   System.IO.Stream stream = session.Stream;
   this.SpinOfAndHandle(stream);
}
where SpinOfAndHandle would handle the communication in a thread separate from the event thread (not part of BlueTools).

Thanks for the reply Andreas,

bassicly, should it be possible for us, by using your bluetools, to accomplisch this kind of communication.
Keep in mind, I'm verry new to all of this stuff.

Kind regards,

Steve
