A meter device which can build and store, and run an application from received file fragments

摘要

Disclosed is a utility meter device (100) including a communications receiver (110) for receiving file fragments for the device, and a microcontroller system (150) with a processing means, and programmable non-volatile memory means (120). The microcontroller system is for building and storing application and data files from the fragments. The microcontroller system then executes a meter application of the device by processing at least one application file, and associated data identified by configuration instructions in at least one of the fragments, to provide data for reconfiguring a meter.
