The Host Controller Interface (HCI) function specification,and the technique to develop Bluetooth module are introduced in this paper. The Bluetooth adapters for 4-channel ±10 V analog input module,4-channel ±10 V analog output module and RS232 serial port are developed,which are used to realize the short-range wireless transmission of signals offered by attitude and rate sensor. The disturbance of Bluetooth communication is discussed,and the developed Bluetooth adapters are examined by communication test. It is shown that the adapters can be used to transmit analog signals of the simulation system.
