In the wireless body area networks

the equipment for monitoring physiological parameters not only requires portability

but also requires of real-time high-speed data transmission. To meet these requirements

a Bluetooth module with an serial peripheral interface（SPI） external interface based on a Cypress programmable system on chip（PSoC） is proposed. The data from the acquisition terminal are transmitted to the PSoC through the SPI interface

and then transmitted to the host computer by Bluetooth. Data reconstruction and visualization are achieved by the host computer. Moreover

various methods such as head-tail character verification and parity check are used to ensure the correctness of data. Experimental results show that the maximum transmission rate can reach1 Mbps

which satisfies the transmission requirement of high-sampling rate signals such as electrocardiograph or electroencephalogram and other high-speed wireless data transmission fields.
