I would like to be able to use my Dataq data recorder wirelessly/bluetooth. is this possible with Arduino uno and bluetooth shield. I would like just to connect My Dataq recorder to arduino via usb and have link to My computer via bluetooth.

My goal is to collect o-10V analog data and have wireless connection to PC. (Dataq device is controlled by Dataq software on PC)

This would be easier to answer if you provided a link to information about your specific recorder. –  Dave Tweed Dec 15 '12 at 16:22

I doubt it is possible to do what you want to do with an Arduino Uno. I assume the "dataq data recorder" acts as a USB "device", and so does the Uno. However, a USB connection needs a "USB host", and as far as I know the Uno is not capable of performing the function of USB host. You would need a more powerful microcontroller for that. In addition you then need to implement the device driver software to communicate with the data recorder on this microcontroller, which may or may not be trivial.

Thank You By the way I love the beers from Tyne "the best in the world" –  steve P Dec 15 '12 at 16:27
I think I should investigate a better analog input to add to arduino instead of using The Dataq recorder Thanks again. –  steve P Dec 15 '12 at 16:29
This is somewhat tangential to the question at hand, but does anyone make an Arduino shield that has the FTDI Vinculum chip on it? This would give the Arduino some limited host/OTG functionality. –  Dave Tweed Dec 15 '12 at 17:00

No, its not worth going down that route. Possible? Yes. But not without a ton of custom written software.

If you have the money, dataq sells ethernet data acquisition devices that you can bridge to your network with a WiFi bridge. That is your best bet for going wireless and keeping your existing software (if you are using their Dll's in a custom program). If you want to keep your existing Dataq device, there are wireless USB kits but their range is limited. Addonics sells a USB to ethernet bridge which may be another alternative. There are also wireless data acquisition devices for industrial data logging that support 0-10V.

I have worked with the Dataq devices before. The dataq and arduino are not very different. The dataq has a microcontroller with a USB UART, just like the arduino. The only difference is the dataq is a finished product and is programmed for a single function along with some analog circuitry for signal conditioning. I also believe the dataq does not use a com port driver but instead a custom protocol that can be accessed via their DLL's. Its been awhile since I last worked with them.
