Setting up your Bluetooth / BLE Module!

(HC-05/6 or JDY-08 / AT-09)

You will need:

• 1 x Bluetooth Module (HC-05/6 or JDY-08 / AT-09)
• 1 x FTDI TTL Serial Module

To Connect your Bluetooth Module to the FTDI

Bluetooth Module	FTDI Board
VCC	VCC

TX	RX
GND	GND

Guide to testing Bluetooth Module

• Upon plugging the FTDI into your computer, a red LED on the bluetooth module should start blinking.

• Open your Arduino IDE, set your COM port to the COM port of the FTDI module, then open the Serial Monitor, and set the baudrate to 115200.

• On your smartphone, open your bluetooth settings, and you should see a bluetooth device by the name of either, "HC-05", "HC-06", "JDY-08", "AT-09", depending on the module you have.

• Pair with the module, using one of the following pairing codes "0000", "000000", "1234", "123456", as the pairing code varies between modules.

• Once paired, download a BLE Serial Communication App, on Android, we recommend, "Serial Bluetooth Terminal", on iOS, we recommend "BluTerm".

• Inside the Serial Communication App, you will need to connect to the bluetooth module, and the Red Blinking LED on the module should now be a solid red LED.

• Type "Test" into the Serial Communication App, and "Test" should appear in the Serial Monitor.

• If you see a strange output in the Serial Monitor, such as ?f<#?"?怘⸮, change the baud rate to 9600, 115200, or 19200, and send "Test" again, and there should be a correct output.
