Wireless date transfer using LinkMatik 2.0 and labview

[mindy696]

hi,

I'm currently doing a project where I'm trying to transfer a signal wirelessly. I have my circuit made on a breadboard. It is followed by the ADC ( LTC 1298 CN8), which is followed by the LinkMatik 2.0. On a labview im using two circuits provided by NI. The server and client VI. I first run the server, where I get the Bluetooth address of my PC Bluetooth device. Then, the obtained address I add to client VI. Once I run the client it brings error 59 saying that network is down or unavailable. 
Can u please advice on this.

Hi midy696

 The tutorial linked below, is one of the best sources for understanding how to set up a Bluetooth application:
Developing Bluetooth Applications with LabVIEW

What you should focus on to begin with, is to connect the two PCs over a Bluetooth connection, where one PC acts as the server and the other PC acts as the client. This is further described in the tutorial. You should use the following two examples to get started: 

-Simple Bluetooth Server VI: labview\examples\comm\Bluetooth.llb

-Simple Bluetooth Client VI: labview\examples\comm\Bluetooth.llb

The error 59 that you are getting means " The network is down, unreachable, or has been reset" and is most likely just an indication that you haven't specified the correct Bluetooth address on the client side. Notice that you have to run the server VI first and then copy the "My Bluetooth Address" into the "address" field on the client before running the client.

The other options you should consider is looking for the correct drivers. Search the LinkMatik and microsoft websites.

Kind regards,

Hi Daniel,

Thank you for your message. I listened to your adviced and have two pcs connected over bluetooth.
The bit that i strugalle with is let say i want to send something from pc1 to pc2.  So I run a server VI in pc1, and then i run a client VI on pc 2. Which bluetooth address should I enter in the pc2 client VI. Because I tried both and I still get a message saying that network is down.
