Abstract
A debug method implemented by a first near field communication (NFC) device includes a step of storing, in a memory of the first NFC device, one or more parameters which are associated with the operation of the first NFC device during a communication with a second distant NFC device. The first NFC device then uses an answer to select (ATS) communication, sent in response to receipt of an answer to select (ATS) communication, to send the stored one or more parameters to the second distant NFC device.
Claims18
A debug method implemented by a first near field communication (NFC) device, comprising:
- storing, in a memory of the first NFC device, one or a plurality of parameters associated with the operation of the first NFC device during a communication with a second distant NFC device.
A debug method implemented by a first near field communication (NFC) device, comprising:
- storing, in a memory of the first NFC device, an end-of-frame time (EOF) parameter used by the first NFC device in connection with a communication with a second NFC device;
- and
- transmitting the stored EOF parameter from the memory of the first NFC device to the second NFC device in an answer to select (ATS) communication sent by the first NFC device in response to a request answer to select (RATS) communication sent by the second NFC device;
- wherein a frame of said ARS communication includes a field linked to a location in the memory where the EOF parameter is stored.
A debug method implemented by a first near field communication (NFC) device, comprising:
- storing, in a memory of the first NFC device, an image of an electromagnetic field associated with a communication between the first NFC device and a second NFC device;
- and
- transmitting the stored image of the electromagnetic field from the memory of the first NFC device to the second NFC device in an answer to select (ATS) communication sent by the first NFC device in response to a request answer to select (RATS) communication sent by the second NFC device;
- wherein a frame of said ARS communication includes a field linked to a location in the memory where the image of the electromagnetic field is stored.
A debug method implemented by a first near field communication (NFC) device, comprising:
- storing, in a memory of the first NFC device, an image of the current induced at the first NFC device during a communication with a second NFC device;
- and
- transmitting the image of the current from the memory of the first NFC device to the second NFC device in an answer to select (ATS) communication sent by the first NFC device in response to a request answer to select (RATS) communication sent by the second NFC device;
- wherein a frame of said ARS communication includes a field linked to a location in the memory where the image of the current is stored.
