An embedded wireless transmitting system for two-dimensional bar code data is designed in this paper based on FreeRTOS. The design method of the software and hardware, together with the mechanism of the point-to-multipoint link control is introduced in detail. The STM32 as the main control MCU, the scan engine and the Bluetooth transmission module are used to achieve the data transmitting between multiple scanners and single cradle.
