l l l l l l l l l Typical -80dBm sensitivity Up to +4dBm RF transmit power Fully Qualified Bluetooth V2.0+EDR 3Mbps Modulation Low Power 1.8V Operation ,1.8 to 3.6V I/O PIO control UART interface with programmable baud rate Integrated PCB antenna SMD package With edge connector

Software features
l l l l l l l l l Default Baud rate: 38400, Data bits:8, Stop bit:1,Parity:No parity, Data control: has. Supported baud rate: 9600,19200,38400,57600,115200,230400,460800. Use CTS and RTS to control the data stream. When a rising pulse is detected in PIO0, device will be disconnected. Status instruction port PIO1: low-disconnected, high-connected; PIO10 connected red led, PIO11 connected green led. When master and slave are paired, red and green led blinks 1time/2s in interval, while disconnected only green led blinks 2times/s. Auto-connect the last device on power as default. Permit matched device connect by default. Default PINCODE:0000. Auto-reconnect in 30 min when disconnected as a result of beyond the range of connection.
