PROBLEM TO BE SOLVED: To efficiently download firmware in a short time. SOLUTION: When a writing program 16 is stored in a RAM 16 of a Bluetooth (R) module 11, a writing program 16 reads an electronic signature command from a flash memory 12 and extracts a model specific to the flash memory included in the read electronic signature command. Then, when firmware to be downloaded is sent from a PC 17, the writing program 16 stores the received firmware in the flash memory 12 based on data specific to the nonvolatile memory model kept by its own program, that is, based on information about block configuration including a writing start address and a writing end address of the flash memory and the size of the block.
