Hi,
I have TI - CC2541 Based custom hardware and wanted to use Labview to communicate the device via BLE (Bluetooth 4.0 Low Energy).
I have gone through many forums. Most says that they doesnt support, but looks lik all are very old forum.
Please help me on this.
Thanks,
Javahar

The question is wrong i feel. It is not LabVIEW what communicates directly with your BT device, but another BT device on your laptop/computer. So if we call your device "TI - CC2541 Based custom hardware" a client, what will you use as a BT host? A BT dongle connected via USB to your PC? Or a built-in BT in your laptop? So first you should be able to connect these two BT devices, and pair them only using your operation system. LabVIEW is the second step after this test.
edit: so explain it in a different way: If your OS supports the BT LowEnergy device, then LabVIEW should also work with it...
edit2: ok, it is indeed more complicated as I thought :)) I have found some fresh discussions on this topic by google:

Hi javhar,
Did you manage to get around this problem?

Hi Javahar,
Labview API uses RFCOMM, which is a connection protocol exposed by winsock interface. If your OS supports this; you can connecct labview to the device.

Hi Kamlesh1,
Do you know if Windows 8.1 or 10 support the winsock interface for BLE? I have broadcom wiced ble device with 5 temperature sensors on board. I want to transmit the sensor data to labview 2014. Is this possible?

Hi,
After lots of research, the way that I found to access the BLE from Labview is via Linking Bluetooth DLL and using its API's.
Let me know, if there is any new hint available on this.
Thanks,

Hi Javahar,
thanks for your response. Would you mind sharing your VI and maybe an outline of the method you had to use to link Bluetooth DLL using its API's? I am PhD student and struggling to get a broadcom wiced ble device to communicate sensor data to labview.

Hi Suzanne and Javahar,
Please check it out this link: http://digital.ni.com/public.nsf/allkb/4BA51235CFC8519086257F5E005E81D5
It clearly says that if you have OS supported for BLE communication; it will work. You can use functions exposed by "Microsoft BluetoothAPIs.dll" and for more info you can visit on this link: https://msdn.microsoft.com/en-us/library/windows/hardware/hh450825
