Abstract (en)
The invention relates to a method (100) for performing a firmware update of a lighting technology device (300), comprising the steps of: supplying (101) firmware update data according to a firmware update protocol; transmitting (103) said firmware update data via a DALI bus (303) using the physical layer of a DALI signal; and receiving (105) said firmware update data at a DALI interface (305) of said lighting technology device (300); wherein the firmware update data is obtained directly by translating changes of the physical states, in particular phase changes of a square wave carrier signal, of the DALI signal into a binary code representing the firmware update data according to the firmware update protocol.
