Software Features:
Default Baud rate: 38400, Data bits:8, Stop bit:1, Parity : No parity, Data control, Supported baud rate:600,19200,38400,57600115200,230400,460800.
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.
