error 1073676294 - unable to connect via bluetooth

[mudithadias]

Hi,

I know there are plenty of discussions on error 1073676294 being a status report more than an error and how you can ignore it. But in my case I cannot ignore it.

So basically we are trying to connect via bluetooth so that we can display/accquire signals generated by a photomultiplier tube (PMT). The computer shows the bluetooth device is connected but when we open the labVIEW VI it gives error 1073676294. When we hit continue/cancel the program exits out. The labVIEW VI is a pre-written program and we cannot access the source code

So guys, any ideas as to what's going on? Is it possibly a hardware malfunction?

Any help is appreciated.

Thanks

Can you see the device in MAX? (Measurement & Automation Explorer)

Hi, yes I can see the com port in MAX. Actually, when I first checked, it had an exclamation mark over it and it would not open a VISA test panel. After, disabling and then enabling the com port, I was able to get rid of the exclamtion mark and now it says the port is working properly.

Hi, I thought I might add in a few more details. I'm not sure if these are relevant or not.

When I open VISA test panel for the COM port and run commands on the basic I/O, I get the following errors.

write --> no error

query --> Hex 0xBFFF0015 - timeout expired before operation completed

read --> Hex 0xBFFF0015 - timeout expired before operation completed

read status byte --> Hex 0xBFFF003A - unable to start operation because setup is invalid(due to attributes being set to an inconsistent state)

clear --> no error

On 'view attributes' --> Is port connected --> invalid property value (Hex 0xBFFF001D)

Can you check that you are configuring your test panel correctly? You can find specifications for the device in the device's manual. Pay special attention to attributes such as baud rate. 

Also, can you communicate with the device with any third party software provided by the company, or an application such as hyperterminal?

Hi,

Yeah we have it in the correct configuration (baud rate, parity, stop bits, etc.). We checked the bluetooth connection with a terminal emulator software and it communicated fine. We tried reinstalling all the software from scratch but it is still giving the same error (1073676294)

Thanks

Hey,

Has this setup ever worked, and if so, what changed?

My theory is that whoever wrote the origional code is using automatic error handling, so that the program cannot ignore this message even though it is a status report and not an error. Our troubleshooting options may be limited since we don't have access to the source code.

Hi Matt, yes the set up has worked before. As you said it's hard with no access to the source code. So now we are looking at writing our own program.

Thanks for the replies!!
