Software features

 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.

 Given a rising pulse in PIO0, device will be disconnected.

 Status instruction port PIO1: low-disconnected, high-connected;

 PIO10 and PIO11 can be connected to red and blue led separately. When master and slave are paired, red and blue led blinks 1time/2s in interval, while disconnected only blue led blinks 2times/s.

 Auto-connect to the last device on power as default.

 Permit pairing device to connect as default.

 Auto-pairing PINCODE:”0000” as default

 Auto-reconnect in 30 min when disconnected as a result of beyond the range of connection.
