【Abstract】 Currently,embedded intelligent terminals centered around STM32 are widely used in numerous fields,bringing tremendous convenience to production and daily life while also posing challenges in terms of maintenance and upgrades. The need for convenient and reliable remote firmware upgrades has become increasingly prominent. This paper proposes a STM32 firmware remote upgrade system based on a dual-mode of 4G and Bluetooth. This system integrates the advantages of 4G networks,such as wide coverage and long-distance communication,with the convenience of Bluetooth for close-range connections,aiming to achieve flexible and efficient firmware upgrade operations.Actual test results indicate that this dual-mode remote upgrade system can operate reliably in various application scenarios,significantly reducing the complexity and cost of STM32 firmware upgrades. It holds great significance in improving the operational and maintenance efficiency of intelligent terminal-based devices and possesses excellent promotion and application value.更多还原
