Method and system for communicating data with an inaccessible electronic device

摘要

The invention relates to a method of communicating data with an electronic device, comprising the step of receiving signals conveyed by an electrical lead. The method is distinguished in that it comprises the following steps: fitting an RF radiofrequency interface with electrical contacts in the device, extracting signals from the electrical lead, and injecting signals resulting from the extracted signals, in the form of frames of radiofrequency signals in the RF interface with electrical contacts. The invention also relates to a radiofrequency communication device, a system comprising the device and a machine using the device.
