Abstract

The invention relates to an electronic device and a method for updating firmware in a number of electronic devices connected to a data network. First, a firmware in a first electronic device of said plurality of electronic devices is configured. Then, a firmware update file is generated in said first electronic device, based upon said configured firmware by using a firmware update file generator. Next, the firmware update file is transmitted from the first electronic device to a number of electronic devices via a data network. Finally, the firmware is updated in the number of electronic devices by executing said firmware update file in each of the electronic devices.
