Disconnected BLE

[Minseo]

Hello.

I'm working on disconnecting ble from the module.

I'm using the app provided by nordic.

I designed it to disconnect the ble when I press the button on the module.

Disconnecting the ble connection worked, but the module automatically reconnects after some time.

Is there a way to disable the connection automatically if the app doesn't request a connection again?

Thank you

The only way a connection can occur is by the Central requesting it.

If you don't want your device to be connectable:

1. Don't advertise at all, or
2. Use non-connectable advertising

Thank you for replying.

Module: function to disconnect ble connection (cannot re-request)

APP: ble connection function

So, if the module is forcibly disconnected and the APP does not request a connection again,

the module will not automatically connect to BLE.

Is this impossible?

Thank you

it makes no difference whether the disconnection was "forced" or not.

Again, the connection has to be initiated by the Central - whether that's the App, or the phone's OS
