Windows 8 Bluetooth Paired But Not Connected
Hi,I need to establish a connection to a remote Bluetooth low energy device from my windows 8 PC ( I have a Bluetooth USB Dongle to connect to the PC). I already know the BLE device's ID. Now I just have to make a connection and send somedata to the device from PC.I searched this blog and perused through the Bluetooth LE samples given here ' but did not find the method I want. I should be able to connect to the deviceby providing the device ID by myself.

But the samples have a method that enumerates the available devices and then connects to the required device. I am working on Visual C (Win32 application).Any sample would be very really helpful.Thanks in advance for your response. Hi,As you suggested, I was able to pair with Bluetooth Low energy device using built UI and installation functions available fromI am able to get a handle to the device and use it in the GATT APIs ( get services and get characteristics) and the buffers obtained were correct.Everything went well till I tried to send a value to the device using. It is giving an error as ACCESSDENIED where as the same device handle worked well with earlier functions.When I tried to give Service Buffer from, as a handle ( as it asked for a service handle) I am getting an erroras INVALIDHANDLE.If you need further information or the code I have written let me know.Please help with this.Thanks in advancephanitk. Hi,I have the same problem here:First, I connect to a BT LE device using the Windows 8 UI. = OKThen I run my own program, that:. Enumerates the devices, which implement the bluetooth LE interface class.
OK = my program finds one device. Enumerates the interfaces for this device. OK = my program finds one interface. Then it gets the device interface path and does a CreateFile to get the device hande. OK = I get a valid path & handle. It uses the handle to call the BluetoothGATTGetServices & characteristics. So far all OK = I can enumerate the services & characteristics.From the moment I try to read a value, register for an event.
I get an ACCESS DENIED error. (I guess in general I get this error as soon as I make an API call which requires communication with the BT LE device over the air??).The msdn API documentation makes distinction between a deviceand a service handle. How to get a service handle?Furthermore, what parameters do I have to give to CreateFile regarding permissions/sharing/security?Any idea what could be wrong?Thx,Dirk.

Hi,Windows 8's IO capabilities is set to DisplayYesNo. The device should respect Io Capability to pairing sequence as defined in the Bluetooth Core specification.In recognition that this problem exists in several device implementation, especially the TI CC2540 based solution, Windows 8.1 has changed its IO capabilities to KeyboardDisplay which addresses this problem.For others in this thread above which seems to have problems opening up the service handle to do Get/Set value operations, this is most likely the same problem.So you have a few options to proceed:1. Get the latest TI FW for the CC2540 from TI.2. Update to Windows 8.1Thanks.
