Enable Hotspot automatically
when I enter the car
So, have you tried enabling your wifi hotspot on your phone when you sit in your car?
So, this solution is for you: When you start your car, your multimedia is automatically connected to your phone. The "WiFi Auto Hotspot" app will enable a Wi-Fi hotspot automatically for you. There is no need for more SIMs to have an internet connection in your car; cards or devices only, only this app.
Permission Screen
After the first launch, the first step is to give the required permissions to keep it running in the background and do all required updates instead of you.
You need to select your Bluetooth devices for what will be required for a WiFi Internet connection from your phone.
After that, your device that requires an internet connection should connect to your phone's Bluetooth. This app will detect it based on your preferences and enable a Wi-Fi hotspot automatically instead of you.
You are not required to deactivate it by yourself. When Bluetooth devices are far away or disconnected, the app will turn off the WiFi hotspot without your interaction.
