Re: java api

Thanks for the reply
We are planning to design a program that uses Bluetooth ,and we couldn't
find an API written in .net. We could find API's in Java so we have to use
Java API's. You can see that socket communication doesn't work in our
situation, so can we use Java API's in .net CF? or do you have another way
to do that?

There are a number of Java Virtual Machines for Pocket PC.
http://www.comp.lancs.ac.uk/computi...nd/ppcjava.html has a nice
chart of some of them. Keep in mind that if you go this route, your whole
app would need to be written in Java. I do not know of a solution to use
Java with .NET.

CONS: Writing the whole app in Java.
PROS: (J2ME) Your app could be ported to the PalmOS, a cell phone or just
about any device capable of running a J2ME VM. You get to use your
Bluetooth API.

Another alternative is to learn how to control the Bluetooth card via
the serial port. This method can be done in .NET CF by P-invoking
CreateFile,ReadFile,WriteFile,CloseHandle, but again there will probably be
a learning curve for trying to learn the serial protocol.

If all you need is Bluetooth connectivity. Just find a vendor that has
native libraries for BlueTooth and pInvoke.
I am sure that HP provides native Bluetooth libraries for the iPaq.

The cost of cross calling between two managed envinronments is too high.

Thanks for the help!!
we plan to communicate with a server via bluetooth .Is it possible to do
that using the serial port?
Thanks in advance,
