hi everybody, My project is about send the ECG signal using a bluetooth module and show the signal using labVIEW program. so far i bought the product and the link below can show it, and i am using PIC16F877A and a decoder L7C9D2 and 7 segment to make sure that the signal can be send and receive, until now i use the DAQ NI-6008 so i tried to connect the Tx, Rx with (a1o) and connect the DAQ assistant to an indicator chart, i got a siganl but its like a noise only..
so my question is :
1- The DAQ can accept the BT frequency ?
2- Do i have to connect the module to the DAQ in the digital or analoge INPUT ?
3- The VI of the labVIEW should be built using VISA (serial configuration) or BLUETOOTH measurements ?
anyone plzzz.

I did something similar. It all depends on what your bluetooth device is doing. Mine was sampling the ecg signal and sending back packets of data. I connected the bluetoooth device to bluetooth on Windows, then connected to the COM port using Visa. I was using Measurement Studio, not Labview, but the connection method would be the same. The bluetooth device needs to use RFCOMM SPP. As it turns out I encountered several quirks of NI VISA which led me to just do a straight Windows Sockets connection to the device instead of Visa.
Your mileage may vary.

i am willing to test the bluetooth platform first before i go throw with the rest, thats why i am using the DAQ so what i did was a simple VI connect the DAQ to a chart then while loop it. so if you want i can post some pix for what the platform look like after i use the DAQ ....i am willing to use the DAQ coz it easy to interface with the LABVIEW and i will place the bluetooth module like blow so you can know what my module can do.......

i am thinking if i pair the bluetooth module as what you said using hyperlink terminal and open the labVIEW how i can it understand that i am PAIRING and show me the signal of it..??/ do i have to use VISA(which is what i am thinking to use )OR i use BLUETOOTH FUNCTIONS in labVIEW???
something else how i can know the UUID for the bluetooth ????
thanx for ur kinds.........

ok sir...i will read all the manual for it, but i have a question:when i want to design the VI do i have to use VISA or bluetooth functions ????
plzzzz reply i need to know this

than for reply............i upload the design PIX and the output of the bluetooth both Tx and Rx, by the way there are anther way but hope can help me if what i am doing is correct or not ????
and if there are anyway to modify the VI.?
thanx
