Bluetooth Low Energy problem / what will be provided by Qt 5.5 BTLE



  • Qt 5.4 provide a Tech Preview of Bluetooth Low Energy (client side support only, on Bluez 4 & 5). My Question is how far the Qt 5.5 Bluetooth Low Energy API final release will supports the BTLE functionality. Especially I am interested in the server side support of BTLE to communicate with iOS (In Apple terms the server side is the peripheral role (has data) like a heart rate sensor). I want to connect from a iPad to a raspberry pi without having a GUI on the rpi and iOS only support BTLE. I run in trouble doing the communication in the other direction. One Problem was the auto disconnect of iOS BTLE after some minutes and due to the given role assignment (rpi=central role/wants data) the communication needs to be initiated from the rpi, keeping the connection by polling, what is not a proper solution for me. Perhaps anyone has an advice or information about what can be awaited from Qt 5.5 regarding BTLE.

    Thank you and Greetings,
    Johannes Bell

    Hi and welcome to devnet,

    You should rather ask that question on the "interest":http://lists.qt-project.org/mailman/listinfo/interest mailing list. You'll find there Qt's developers/maintainers. This forum is more user oriented.
