hello, thank you for the URL of IP camera, please can you help to activate this application by sending " Init MJPEG Server.vi", "Send image to MJPEG Server.vi",

"is MPJEG server Ranning.vi" and "dispose MJPEG Server.vi". Because I have not succeeded to find them. Thanks

Hi udka,

thank you for your help

[OmarBahri]

Hi,

Is that we can do the same application with a connection via Bluetooth ?

thank you !

[udka]

I guess, for me IP camera didn't work. And i used Droid cam similar app i got in play store. and i was able to connect it with labview.

-I suggest you to open separate thread if needed, because i don't see how your current problem is related to this thread, prefarably in Machine vision board.

Hi udka, thank you for your help.

Can you give me your email to discuss the problems ?

Thanks

Hi bahri77,
-If you have any other technical problems, post here in the forum so that many people can help you in better way.
-You can send private message(PM) to particular user if needed and i don't think email address is necessary here.
-For sending PMs click on user name below which you should see option "Send this user a private message".

thank you udka for your help,

Can I brodcast my Android camera with labview 2012 via a bluetooth connection ?

I didn't activate this application with TCP/IP protocol in my PC.

And my objectif is to broadcast via bluetooth.

Thanks,

[udka]

I didn't understand your question properly.Let me tell you what i understood.
-You want to broadcast video from your android camera(phone or camera??).
-Mode of transfer should be via bluetooth.
-You need to receive that video in labview.

-Yes you can broadcast you android camera video through bluetooth/usb/wifi using apps like Droidcam, WO Webcam Lite (Which i checked) and there might others also.
-These apps will create virtual device in your MAX(Measurement and automation Explorer)
-First check whether you can see your android virtual device in MAX and try grab or snap to see whether you're getting video or not.
-If it is working in MAX it will work in labview also.
-I don't know how to get video directly through bluetooth from labview.
