In the wireless communication environment, the wireless module based on UART interface can release the hard?ware and software resources of CPU. It′s easy to use,and has a wide range of applications. A low cost scheme to design wire?less module is introduced in this paper. According to the encapsulation wireless data packet of nRF24L01 and the slow?speed feature of the UART interface,the double?buffer transmitting and receiving the UART data was designed, the corresponding soft?ware and hardware were developed,and the reliable wireless data communication was realized. Experiments show that the wire?less module with UART interface achieves the desired effect, which implements a reliable transmission rate of 128 000 b/s, and meets the most requirements of wireless communication function.
