the code is down below and my question is how can I used it in the code blocks
Any help will be appreciated thanks..

private void unpairDevice(BluetoothDevice device) {
    try {
        Method method = device.getClass().getMethod("removeBond", (Class[]) null);
        method.invoke(device, (Object[]) null);
    } catch (Exception e) {
        e.printStackTrace();
              
Hi @Manuel_Hernandez,

Did you manage to solve this problema from AppInventor, without the need to program an extension?
Thanks,
              
Thanks @Taifun four your answer,
I apologize for omitting that my devices are BLE connected (and paired/bond).

My app forget their addresses but it doesnt remove the bond info from Android.
Thanks anyway,

Hi @Waloui

I'm sorry to tell you that I can't find a solution from App Inventor blocks, so I decided to incorporate security at the application level encoding the transmitted data.
Also, I removed the pairing/bonding process and made connection through saved real MAC address of my devices; Therefore, I do a kind of bonding (only at one end, the central one) at the application level without the intervention of the operating system. At the other end (peripherics) only one simultaneous connection is allowed (no whitelist used).
For my application, these solutions work. I'm sorry I can't help.
