I'm converting an application that has been running on a Handera 330 to a
Tungsten T3 using a custom portable keypad. In the past there was a
physical connection between the Handera 330 and a Keypad and laser scanner
through the serial port. I have it working on the Tungsten now using a
virtual port to connect the keypad to the Tungsten via Bluetooth thanks to
some help I got on this forum. (I've found that the connection between the
PDA and the keypad can be made through thin sheet steel.) Eventually I want
to add a Bluetooth-enabled laser scanner but the documentation indicates
that I can have only one virtual port open at a time. That would be OK for
some applications but this one has to be able to accept input from either
the keypad or the scanner at any time. Does anyone have any suggestions as
to how I can do this? I haven't tried to open two virtual ports at a time
but the documentation is pretty specific on that point. I will try it in a
I've been using Bluetooth to Hotsync and that's a huge convenience to me. I
think my users are going to love it.
I'm passing files from one PDA to another via the exchange manager and
Bluetooth and that's working pretty well. The only problem is I have to to
a exgput, exgdbwrite, exgdisconnect for each file and there might be a
dozen. That means someone has to respond to a popup on each side of the
transfer for each file. It doesn't seem to start making the connection
until it executes the disconnect. I tried several ways around this so I
could make the connection once, transfer several files, then disconnect but
I couldn't get anything to work. I did IR pretty much the same way but it
didn't trouble users for responses so much. Does anyone know a way to
transfer several files with just one connection?
I also plan to use Bluetooth to print to a Bluetooth enabled printer. I can
close the virtual port to the keypad to print so I don't have the problem
with a single virtual port. I don't have a Bluetooth enabled printer but I
tested it by transmitting into hyperterminal and it seems to work ok.
All-in-all I feel like Bluetooth is a huge step foreward for computing.
