Is Bluetooth 3.0 + HS supported by the proximity framework?

    Question

  • I'm trying to establish a peer-to-peer connection between two devices from a Metro app. Connecting over Wi-Fi Direct isn't working most likely because one of the devices doesn't have Wi-Fi Direct. As a result, I've been using Bluetooth which connects perfectly fine.

    The problem however lies in the fact that the connection I'm getting is way too slow for my needs. I've tested it and it's around 200kB/s. I know that speed claims are always theoretical and in the real-world you'll never see those numbers, but Bluetooth 3.0 + HS is rated at 24Mb/s so I would expect somewhere between 1-2MB/s real-world. The numbers that I'm getting seem to fit more with the non-HS Bluetooth connection.

    The question then arises, does the Bluetooth connection established with the Proximity framework support Bluetooth 3.0 + HS?

  • There is no support for Bluetooth 3.0+HS in Windows. Especially the HS component i.e. high speed WiFi as transport.  See e.g. "Bth_FAQ.docx" at http://msdn.microsoft.com/en-us/library/windows/hardware/gg487349.aspx Note no 3.0 in Table 1.

    How are you making the initial link? That is only by NFC or Wi-Fi Direct. Do you have NFC hardware and thus are tapping to connect?

  • Thanks for the answer Alan. That basically confirmed what I was suspecting.

    And yes, I'm establishing the initial connection with an NFC tap.
