A method for controlling a cooking appliance using a mobile terminal that is separate from the cooking appliance, both of which have a controller and a BLE communication device, involves the following steps being performed: switching on the cooking appliance and the terminal, setting up a communication link between the two by means of a specified user process on the cooking appliance or on the terminal and confirming the set-up of the communication link by means of a user process by the user on the cooking appliance. A signal strength of the communication link between the two communication devices at the time of confirmation of the communication link on the cooking appliance is stored and is monitored during use. If the signal strength drops below a prescribed signal strength limit value, then user commands from the mobile terminal are blocked.
