METHOD FOR DEVICE DIAGNOSIS

A system for device diagnostics of an aerosol-generating device and a charging device associated with the aerosol-generating device is disclosed. The system comprises: a near field communication module, the near field communication module comprising a nonvolatile memory; and a control unit. The control unit is configured to receive an indication of an error occurrence and update an error data log stored in the non-volatile memory by storing an error data entry associated with the error occurrence to the error data log. The error data entry is configured to be read by an external device even if the device including the near field communication module is not powered. 本发明公开了一种用于气溶胶生成装置和与气溶胶生成装置相关联的充电装置的装置诊断的系统。所述系统包括：近场通信模块，所述近场通信模块包括非易失性存储器；以及控制单元。所述控制单元被配置成接收错误发生的指示，并且通过将与所述错误发生相关联的错误数据条目存储到存储在所述非易失性存储器中的错误数据日志来更新所述错误数据日志。所述错误数据条目被配置成即使包括近场通信模块的装置未被供电，也被外部装置读取。
