Actually, there is no need to fiddle with the BtLib. Even if you need to
Discover a single device (to remember it's address for later use) you
just call the DiscoverSingleDevice function. Or you don't care and just
open the serial connection. the BtStack will go and ask the user which
device he wants to connect to.

!!!!!!!!! THANK YOU! I think I will be well on my way with that detailed
help you gave me. I do not remember any instructions like that in the
ACCESS documentation...which didn't cover bluetooth specifically and
seems to be a little outdated.
Oh also, I didn't know that you could write palm apps with Pascal... I'm
using C++. From what you said, I doubt the process is much different.
Thanks!!

Error 0x03EA sounds like you haven't paired the device you are
connecting with, you need to go through this process before you can
send and receive any data. Also note that before using SrmExtOpen to
open your Bluetooth serial connection you must close the Bluetooth
library otherwise you will get error 0x30A.
So after pairing the devices, Palm->mobile phone or Palm->modem or
Palm->pc etc (once done you should not need to do this everytime), the
process I go through to setup and use a Bluetooth serial connection is:
1) open the Bluetooth lib
2) setup a callback routine to deal with Bluetooth discovery responses
(BtLibRegisterManagementNotification)
3) start the discovery process (BtLibStartInquiry)
4) find out if the device I want to connect to is in range and
responding in my callback routine setup in step 2
5) once I have the device, fill in the Palm structures sppUid,
btParams and SrmConfig
6) close the BtLib (**important**!)
7) open the serial connection using SrmExtOpen
8) send data to the paired device over the serial ink using SrmSend
8) use SrmReceiveWait to wait for incoming traffic and receive that
data using SrmReceive
9) finally once I am done, use SrmClose to close the serial port
If you want I have a working example in Pascal which goes through the
processes to connect to a Bluetooth modem.
Hope this helps!

Hi,
I'm relatively new to Palm OS Programming (but not programming in
general). I can't seem to get the serial port open with the Bluetooth
Connection panel serial port. The VirtRfComm doesn't work either, but
I know that needs some extra settings passed to SrmOpenEx to open.
I've been trying this with SrmOpen and SrmOpenBackground. Those
functions keep failing with something like 0x03EA or something like
that. This used to make my phone go into a reset loop until i deleted
the program. I think i had other bad files that were causing that,
though.
So anyways, whats the REAL way to open a bluetooth serial connection?
Thanks,
Shorin
