		TextView txt= new TextView(this);
		txt.setText(send);
		llt.addView(txt);
	}
 
}

J'ai essayé de l'activer avec bt.enable(); Mais ça ne fonctionne pas.

Salut,

bt.enable(); Ne jamais utiliser !!!

public boolean enable ()

Added in API level 5
Turn on the local Bluetooth adapter—do not use without explicit user action to turn on Bluetooth.

This powers on the underlying Bluetooth hardware, and starts all Bluetooth system services.

Bluetooth should never be enabled without direct user consent. If you want to turn on Bluetooth in order to create a wireless connection, you should use the ACTION_REQUEST_ENABLE Intent, which will raise a dialog that requests user permission to turn on Bluetooth. The enable() method is provided only for applications that include a user interface for changing system settings, such as a "power manager" app.

This is an asynchronous call: it will return immediately, and clients should listen for ACTION_STATE_CHANGED to be notified of subsequent adapter state changes. If this call returns true, then the adapter state will immediately transition from STATE_OFF to STATE_TURNING_ON, and some time later transition to either STATE_OFF or STATE_ON. If this call returns false then there was an immediate problem that will prevent the adapter from being turned on - such as Airplane mode, or the adapter is already turned on.

Requires the BLUETOOTH_ADMIN permission

Returns
true to indicate adapter startup has begun, or false on immediate error

Appelle par conséquent l'intent sur ACTION_REQUEST_ENABLE et ajoute la permission BLUETOOTH_ADMIN.
