HAND HELD POWER TOOL, SYSTEM AND METHOD
Arrangement and methods for communicating data between a control system (100) of a power tool (10) and a computing device (20). The arrangement (1) comprises a control system (100) with a plurality of electronic control units, ECUs (110, 120), a computing device (20), and a connecting unit (30) comprising a data connection (32). The plurality of ECUs (110, 120) are connected to a common bus of the control system (100). Each of the plurality of ECUs (110, 120) has a passive service mode (201) and an active service mode (202). The computing device is operable of transmitting a wake-up communication signal to the plurality of ECUs (110, 120), which wake-up communication signal comprises an ID of a selected ECU (110, 120) out of the plurality of ECUs (110, 120). The selected ECU (110, 120) is operable to switch from the passive service mode (201) to the active service mode (202) as a response to detecting its ID in the wake-up communication signal, so as to allow communication of data between the selected ECU (110, 120) and the computing device (20) via the data connection.
