Application of Near-Field Bluetooth Technology in Remote Firmware Upgrading of Power Equipment

This paper proposes a remote firmware upgrading solution for power equipment based on Near-Field Bluetooth (BLE) technology, aiming to achieve remote and flexible firmware upgrades through wireless transmission. The focus of the research is on optimizing the firmware transmission protocol to improve transmission efficiency and stability. Measures such as data chunking, CRC checksum, and digital signature encryption are employed to ensure the integrity and security of the data. In addition, an error detection and recovery mechanism is designed to handle anomalies during the upgrade process. Experimental results show that the proposed system exhibits good stability and high success rates in various environments, effectively meeting the requirements of remote firmware upgrading for power equipment.
