Abstract: The paper presents a wireless telecommunications system design based on the STM32 MCU and RS485 bus network to address the low accuracy,poor real-time performance and unstable data transmission of traditional telecommunication systems.The low-power high-performance STM32 offers rich interfaces for portable communications.The standard communication interfaces of STM32 are used to achieve a wireless telecommunications system based on the RS485 bus and the MODBUS protocol NRF24L01 wireless receiver chip.Experiments show that the error rate is about 0.015 with greatly improved reliability and stability.

Key words: STM32;communications systems;NRF24L01
