Send side, generally expressed as their own sender, normal communication RXD must be connected to another device.

the receiving end, generally expressed as himself on the receiving end, normal communication TXD must be connected to another device.

RXD when normal communication access other devices TXD, so if you want to receive data sent by itself as the name suggests, it is their own to receive data transmitted, namely own TXD directly connected to RXD, used to transmit and receive test itself It is normal, is the quickest and easiest way to test when a problem occurs first do this test to determine whether a product failure . Also known as the loopback test.

usually represent binary data, the provisions of + 5V is equivalent to a logical "1", 0V is equivalent to a logical "0", known as TTL signal system, is positive logic

using -12V to -3V, equivalent to a logical "0", + 3V to + 12V logic level, equivalent to a logical "1" is a negative logic

The Bluetooth module can only be connected VCC 5V, can not pick 3.3V!

Baud 38400,8 data bits, 1 stop bit, no parity. After each command input is complete, you must press the Enter key again sent!

Enter the AT, press the Enter key to send, the Bluetooth module will return OK

The default is slave mode, without modification)
