A method of configuring power tool electronics in a hand-held power tool (10) having sensor means (20) for acquiring measurement data, a control unit (50) for processing measurement data and for controlling power tool functions, and a data transmission unit (30), includes transmitting data between the data transmission unit (30) and an evaluation location (62) by means of a mobile wireless network, with the power tool electronics being awakened from a quiescent mode (70) and activated at a time stored as a time parameter in a control program, retrieving a configuration file provided by the evaluation location (62) by the data transmission unit (30) via the mobile wireless network, and checking the response received from the mobile wireless network to determine whether or not it contains a new configuration file. If a configuration file was received, the parameters contained in the configuration file are implemented (77) in the control program for the power tool electronics. The power tool electronics is then returned to the quiescent mode (70) again.
