System and method for commissioning devices
First Claim
1. A system for commissioning devices, the system comprising:
- a first device comprising an RFID tag and a host processor;
a second device;
wherein the second device is configured to generate an electromagnetic field, the RFID tag is configured to detect the electromagnetic field and wake up the host processor upon detecting said electromagnetic field in order for the second device to communicate with the host processor, the RFID tag comprises a tag controller which is configured to send a wake-up signal to the host processor in order to wake up the host processor only when data are read from and/or written to a predetermined area of memory; and
a separate wake-up circuit comprising a tag selection detector capable of detecting whether the RFID tag continues interacting for a longer period of time after an initial field is detected in the antenna coil.

Abstract
According to an aspect of the invention a system for commissioning devices is provided, which system comprises: a first device and a second device; an RFID tag comprised in the first device; a host processor comprised in the first device; wherein the second device is arranged to generate an electromagnetic field; wherein the RFID tag is arranged to detect the electromagnetic field and to wake up the host processor upon detecting said electromagnetic field in order for the second device to communicate with the host processor. Furthermore, a corresponding method for commissioning devices is provided. Since the RFID tag comprised in the first device is arranged to wake up the host processor, an end-user does not have to switch on the first device manually. Therefore, the user interaction is simplified. Furthermore, there is no need for a separate power button on the first device. The latter reduces cost and simplifies the design of the first device.

10. A method for commissioning a first device comprising an RFID tag and a host processor and a second device, the method comprising:
-
detecting, with the RFID tag, an electromagnetic field generated by the second device; waking up the host processor upon detecting an electromagnetic field in order for the second device to communicate with the host processor; sending, with a tag controller in the RFID tag, a wake-up signal to the host processor in order to wake up the host processor only when data are read from and/or written to predetermined areas of a tag memory; and detecting, with a tag selection detector, whether the RFID tag continues interacting for a longer period of time after an initial field is detected in the antenna coil. - View Dependent Claims (11, 12, 13, 14, 15, 16)
