Abstract:A wireless communication system which is using iPhone mobile phone terminal and RT5350 module to transfer instruction and data to each other is proposed in the paper. The system establishes a wireless LAN platform, regarding the STM32 microcontroller and the RT5350 module as the hardware platform, the intelligent mobile phone which equipped with IOS system as the client, combining the TCP/IP protocol and serial transmission protocol and implementing the wireless transmission of video data stream, the mobile phone control instruction, and associated data. This system not only realizes the down transmission of the control instruction, but also realizes the upload transmission of data information. After testing, the wireless communication system can smoothly watch the video collected by camera , control the hardware without error and transmit data without error within a range of 35 meters, and the two transmission process does not interfere with each other.
