Not up-to-date with Bluez 5.50 stack

[dhruvkakadiya]

There are several things need to be updated in bluez_components.py file as to support latest functionalities in the latest stack. Also several functionalities are missing like setting data values and local name in the advertisement.

For example, I have below changes in my local branch.

I have tested above changes for Bluez5-5.50 stack and they are working fine. I am also looking at changes to set advertising params as well.

Thanks for the info. I haven't actively worked on this demo project since I created it in 2016. Back then BlueZ's BLE advertisement API was still marked as experimental. I pulled the code in bluez_components.py from BlueZ's own examples, so it is no surprise that some things have changed. For now I don't have enough time to come back to this project, but I will keep this issue open so that others can see that BlueZ's API has changed in the meantime.
