An embedded short-range wireless data communication protocol design

Abstract

In the field of embedded wireless data communication system, such as remote measurement and control, wireless meter reading, information appliances, wireless mouse or keyboard, it usually needs to design a small custom protocol to directly access the hardware. To solve this problem, designed an embedded wireless data communication protocol, Using special data frame format to solve unreliable data link problem, Using roll-call polling methods to achieve multi-point access, Using UART to achieve transceiver between MCU and RF chip, Using stop-waiting protocol to achieve the flow and error control.
