Abstract
The invention relates to a firmware over-the-air (FOTA) method for updating building services, in particular lighting technology installations, comprising multiple devices which are connected to a server as a mesh network, wherein the method comprises the following steps: storing a firmware update image sent by the server in a respective memory of each device, and triggering the copying of the firmware update from the memory to an internal memory of a microcontroller of each of the devices by means of a trigger command issued by the server, wherein, within a predefined time period (timeout) after the trigger command is issued, the server uses feedback from the devices to check whether each device has received the firmware update image and the trigger command, and wherein the copying does not take place until after the predefined time period has elapsed.
