Thanks I watched this video 3 times, but he talks about profile registration and the auto connect very briefly so I tried everything that comes to mind, but can’t make it to work If you have done it can you post some pseudo code for the code execution ? I am sure it is not very complicated , just still too new to the whole concept. > On 18 May 2017, at 18:41, Barry Byford <31baz66@xxxxxxxxx> wrote: > > Szymon Janc talks through using BlueZ for BLE on this video: > https://youtu.be/VMDyebKT5c4 > Slides at: > http://events.linuxfoundation.org/sites/events/files/slides/Doing%20Bluetooth%20Low%20Energy%20on%20Linux.pdf > > Should be helpful for you to understand the logic. > > > On 17 May 2017 at 11:35, Krasi Georgiev <krasi.root@xxxxxxxxx> wrote: >> 3 hours later and still no luck :( >> >> I am reading all api documents over and over again and can’t understand the logic. >> >> I think I need to register an object that implements the org.bluez.GattProfile1 interface, but what should be the bus name and object path for this object I am completely unsure... >> >> Desperate for any useful info so thanks in advance :) >> >>> On 16 May 2017, at 23:31, Krasi Georgiev <krasi.root@xxxxxxxxx> wrote: >>> >>> Thanks >>> I already looked at these, but they don’t cover what I need and also a but high level with the dbus python package which hides most of the important details. >>> >>> Anyway I think I got a better idea now. I think I need to register the org.bluez.GattProfile1 interface in the dbus and then call org.bluez.ProfileManager1.RegisterProfile , will test it tomorrow and hopefully I will get it going. >>> >>> >>>> On 16 May 2017, at 22:08, Barry Byford <31baz66@xxxxxxxxx> wrote: >>>> >>>> Hello Krasi, >>>> >>>> >>>> On 16 May 2017 at 12:42, Krasi Georgiev <krasi.root@xxxxxxxxx> wrote: >>>>> Hi all >>>>> >>>>> Can you give me a quick example with a pseudo code (or using qdbus) for workflow steps how to setup an >>>>> auto connect to a device that supports given UUID service (0000180f-0000-1000-8000-00805f9b34fb - Battery Service) >>>> >>>> The examples for BlueZ are in the test directory.
