Securing bluetooth

[ie2778]

The security side of the bluetooth is neglected. I don't want to keep my esp32 discoverable and pairable. I was able to wire a code that make the esp32 discoverable and pairable for 30s on start then it is no longer discoverable. I am trying to add this code in the BluetoothA2DPSink.h but i am not a big C++ coder so i didn't understand anything.

I traced the code all the way to start() but it doesn't do anything, so i am not sure where and what to add.

I would be nice if this feuture is implemented.

Hey , i don't really know what is your project about , but if you want to use Bluetooth between 2 esp32 , you can try the ESPNOW communication .
Hope it can help !
Good luck

i will be using it as a wireless audio receiver for my car, so alot of peope will be around and i defenitely don't need anyone to connect. But regardless of the purpose, it shouldn't be open all the time. I leave in a dense area and i had a wireless receiver and my neighbor connected to it, and every time i used it, it automatically connects to his phone and there is no way for me to disconnect it.

Just read the Access Protection/Authentication in the Wiki!

this somewhat solves it. The last part was how i set the bluetooth to undiscoverable, so i will go back to doing that, but another thing is the phone does not auto reconnect to esp32.
