- connection signature is, for example, a key by means of which the communication of the first communication channel is encrypted. This key is exchanged exclusively via the second communication channel.
- the second communication channel preferably works with a protocol that differs from the first communication channel, but in particular a different frequency range is used for the transmission of the key.
- the first communication channel uses a frequency range that differs from the frequency range of the second communication channel.

- the cookware 4 comprises a transceiver 9 accommodated here in the handle device.
- the transceiver 9 is suitable and designed here to communicate at least temporarily wirelessly via a first communication channel 11 and/or via a second communication channel 12. It is also exemplified in the embodiment shown here that one or more controls 13, one or more output devices 16 and z. B. an acceleration sensor 14 can be integrated into the handle device.
- the operating elements 13 are made available here by output devices 16 which, in the exemplary embodiment shown, comprise a display device or a display element.
- the handle device can include a display or a touch display, so that the operating elements 13 are made available by the output device or the display device or are included in it or are integrated into it.
- the cooking utensil 4 is placed here on the installation device 6 of the hob device 3 so that the cooking utensil 4 can be inductively heated here by means of the heating device 7 .
- the cooking utensil 4 has a first antenna device 21 for the first communication channel 11 .
- the hob device 3 also has a first antenna device 20 for the implementation of the first communication channel 11. Signals are transmitted between the first antenna devices 20, 21 by means of electromagnetic waves.
- the cooking utensil 4 has a second antenna device 19 for the second communication channel 12 .
- the hob device 3 also has a second antenna device 18 for implementing the second communication channel 12. Signals are transmitted between the second antenna devices 18, 19 by means of electromagnetic waves.
- the first antenna device 21 provided in the cooking utensil 4 and the second antenna device 19 provided in the cooking utensil 4 are elements of the transceiver device 9.
- the first antenna device 20 provided in the hob device 3 and the second antenna device 18 provided in the hob device 3 are elements of the communication device 5.
- the transceiver 9 and the communication device 5 can at least temporarily communicate wirelessly with one another via the first communication channel 11 and via the second communication channel 12.
- the first communication channel 11 is provided by a Bluetooth connection and the second communication channel 12 is provided by a transmission protocol and/or a radio frequency which differs from a Bluetooth connection, preferably the second communication channel 12 is provided by an NFC connection.
- the cooking system 1 shown here purely schematically is suitable and designed to carry out a method according to the invention for setting up such a cooking system 1 .
- the transceiver 9 is activated here by actuating the operating element 13, so that the transceiver 9 is ready to transmit and receive signals here.
- the transmitter/receiver device 9 can also alternatively be activated by an acceleration, such as a jerky movement of the cooking utensil 4. Such an acceleration can be detected here by means of the acceleration sensor 14 integrated into the handle device, whereupon the transmitter/receiver device 9 can be activated here.
- the procedure can include the following steps:
- the transceiver 9 is in a mode here in which signals with an identification signature can be received and sent.
- the transceiver 9 is in a mode here in which signals of a connection signature can be received here.
- the actuation of the operating device 15 accommodated here by the hob device 3 activates the communication device 5 here, so that the communication device 5 here is ready to send and receive signals.
- the procedure can include the following steps:
- the communication device 5 is here in a mode in which signals with an identification signature can be received and sent here.
- the communication device 5 is in a mode here in which signals of the connection signature can be sent here.
- a possible embodiment of the method provides that the transceiver 9 transmits an identification signature of a cookware 4 via the first communication channel 11 .
- the communication device 5 transmits the connection signature via the second communication channel 12 .
- the process can also initially be initiated by the communication device 5 which sends the connection signature via the second communication channel 12 . If this is received by the transceiver 5 , the transceiver 9 will send a signal with the identification signature via the first communication channel 11 .
- connection signature is then recorded by the transceiver 9 and stored.
- the transceiver 9 After the transceiver 9 has received and stored the connection signature, further transmission of signals takes place in the first communication channel 11 including the connection signature.
- the signals of the first communication channel 11 are encrypted with the connection signature.
- the communication device 5 also subsequently sends a signal via the first communication channel 11 to the transceiver 9 only together with the connection signature.
- connection signature is used to establish secure and here encrypted communication via the first communication channel 11 provided here by a Bluetooth connection.
- connection signature is exchanged via the second communication channel 12, which is also referred to as so-called out-of-band authentication.
- connection signatures or connection keys or passwords it is possible for further signals and/or connection signatures or connection keys or passwords to be automatically exchanged between the transceiver device 9 and the communication device 5 via the first communication channel 11 and/or the second communication channel 12.
- connection signature is stored here by the transceiver 9 and the communication device 5, so that the connection signature can also be called up at a later point in time and thus repeated encrypted communication via the first communication channel 11 can also be automatically established using the connection signature at a later point in time is.
- a secure Bluetooth connection is automatically established between the transceiver 9 and the communication device 5 by means of the connection signature, and the output device 16 emits an acoustic signal here in addition to a possible display.
- the exchange of the connection signature via the second communication channel 12 is preferably only required once when teaching an individual cookware 4 to an individual cooktop device 3 .
- the exchange of the connection signature via the second communication channel 12 may become necessary again if an energy store in the cooking utensil 4 has been renewed.
