The project contains the android client for this project: https://github.com/gtntdev/-WifiConfigViaBluetooth-Docker
It is based on this project.
Just clone the repo, install the docker server and use the app to configure your Wifi.
Many thanks to Brendan Myers for your contributions!
Note: the projects aren't compatible as I changed not only the GUI but added some basic JSON network interface!
