Application
Bluetooth relay module application method
      1>. Install Bluespp Bluetooth serial port, APP
      2>. Set up the Bluetooth serial port APP, open APP, switch to switch options, long set according to the grey box pop-up menu, select sixteen hex, open the instruction A0 01 01 A2, when you close the command A0 01 00 A1, attention to no more spaces, and the format should be consistent.
      3>. Power the Bluetooth relay module, in the APP point connection for searching, the first pairing time will be longer, search more than a few times (also can use your own Bluetooth search to pair). After pairing, you can use the APP control module.

Reserve the UART debugging interface, which can be used to modify the Bluetooth pairing password.

The basic function and instructions

• IN + : DC 12 v power supply to the anode
• IN - : DC 12 v power supply
• COM: public side
• NO: relay normally open interface, relay and impending, before and after absorption and COM sub.
• NC: relay normally closed interface, relay and with COM nipple, before and after the impending.

Basic instructions:
After wiring correctly, using cellphone to search Bluetooth devices and connect, Pairing password is 1234. Input order and send by hexadecimal (when the Input order is A00101A2 open the relay, when the Input order is A00100A1 close the relay)

Note:  When Wiring NO COM or NC COM: only use one relay state at a time.
Cannot access any two ports or will cause short circuit.
