Method for applying correction to smart-meter instructions

A smart meter configured to apply a correction to a set of instructions executed by a controller of the smart meter, said smart meter being configured to communicate with a centralised server via a communication network, the controller comprising a processor incorporating a debugging module configured to stop execution of the set of instructions when it is detected that a stop point is reached and to generate an associated hardware interrupt, the controller being configured for:

• receiving a new-correction message via an interface of said smart meter with said communication network, said message supplying the correction and a point of stopping application of the correction in the set of instructions executed by said controller;
• recording instructions of the correction supplied by said message in non-volatile memory with a view to a future restarting of the smart meter, as well as in random access memory with a view that the smart meter will not be restarted;
• configuring the debugging module with said point of stopping application of the correction;
• and
• applying on the fly the instructions of the correction recorded in the random access memory, when a hardware interrupt associated with said point of stopping application of the correction is detected.
