WM% and Bluetooth

[JosephByrns]

I have recently got a WM5 PDA (Mio A701). I need to establish an SPP
bluetooth connection to various devices. Previously (on MS BT PPC 2003
PDAs) I would use the OpenNetSDK to identify the presence of relevant serial
devices, and establish a BT serial connection on the fly, then use standard
RS232 comms stuff to access the devices.

When using Widcomm stack devices I simply messed around with registry
settings on the PDAs, the application holding a list of MAC addresses of the
relevant devices and changing registry settings accordingly.

My problem is what can I do with WM5 PDAs? I cannot seem to find any
registry settings to change (containing mac addresses anyway). Is there an
update to the OpenNET SDK? Is there another method altogether I should be
using?

Thanks.

As with previous generations of devices there are still cases where devices
have a third-party Bluetooth stack, though the Microsoft stack is used on
most WM5 devices. This is accessible through the same APIs and Sockets
support. The latest version of the library can be found at
http://32feet.net. For Widcomm/Broadcom there is an SDK which is now
available free but it's for native code so you'd need to do a lot of interop
work.

Great, I'll give it a try, the Mio A701 does have a MS BT stack (or so it
would seem from the interface and registry entries).

Thanks.

Other BT related questions:

- I'd like to use the serial port mapping of the BT stack, but on every
device the port number is something different. Is there a foolproof
way (independant of the stack vendor) to detect that port?

- what about pairing etc. in this scenario? We'd use the SPP and a
custom made BT adaptor so it had to be paired once with the PDA, right
and then could simply be switched on and the connection will be
reestablished if BT is on on the PDA side?

Or is there any good free ressource on the net to read about such BT
basics? Or how to select the device to communicate with? I need a easy
connection process because the user's won't be techies...
