Bluetooth: Connection problem between dual-mode (LE + Classic) device and dual-mode host RRS feed

  • Question

  • When dual-mode Bluetooth device is connected to a PC with a dual-mode host adapter, only classic profiles become available and GATT based services are not enumerated by Windows 10 1607.  Apparently, current Windows 10 1) doesn't allow simultaneous use of LE and classic connection for one device, and 2) doesn't support GATT over classic.

    Is there a way to access GATT in this situation (preferably, without killing classic profiles)?

    And, does Microsoft have plan to solve the above limitation in the future version of Windows 10?

  • You are correct we do not support GATT over classic Bluetooth; this is something we are considering for future versions. However, you can use both classic and LE at the same time.

    Before our upcoming Windows Creator's Update (RS2) is released you will need to also pair with LE, in RS2 we've removed the need to pair to use GATT. This can be done with our Paring feature there is a sample.

    Once paired (if needed) you can use GATT we have a sample for that as well.

  • Hello Frank,

    Thank you for your response.

    Before our upcoming Windows Creator's Update (RS2) is released you will need to also pair with LE ...

    Do you mean that current Windows 10 (1607) allows simultaneous classic/LE pairing with one device?  If so, could you elaborate how to do that?  As far as I know, dual-mode device is always paired for classic, and once paired for classic, I don't see any option to further pair with LE...
