Firmware overwriting method in paired use wireless microphone and receiver

A firmware overwriting method applicable for paired use at least one wireless microphone and at least one receiver, the at least one wireless microphone comprising a wireless microphone processing module, a wireless microphone wireless transceiver module, and a wireless microphone storage module storing a wireless microphone firmware and an overwriting program;

• and the at least one receiver comprising a receiver processing module, a receiver wireless transceiver module, and a receiver storage module storing a determining program, an installed receiver firmware and an installed wireless microphone compatible backup firmware;
• characterized in that the firmware overwriting method applicable for the paired use at least one wireless microphone and at least one receiver comprising:
• building a wireless connection between the at least one wireless microphone and the at least one receiver;
• executing the determining program to determine if the installed wireless microphone compatible backup firmware is the same as the wireless microphone firmware by the receiver processing module;
• in response to the installed wireless microphone compatible backup firmware is determined to be the same as the wireless microphone firmware, the overwriting program is not executed by the wireless microphone processing module;
• and
• in response to the installed wireless microphone compatible backup firmware is determined to be different from the wireless microphone firmware, the receiver processing module sends a command to the wireless microphone processing module to download the installed wireless microphone compatible backup firmware from the receiver storage module, and the overwriting program is executed by the wireless microphone processing module to overwrite the wireless microphone firmware stored in the wireless microphone storage module with the installed wireless microphone compatible backup firmware.
