Used for communication between the Arduino board and a computer or other devices. All Arduino boards have at least one serial port (also known as a UART or USART), and some have several.
Bluetooth is a radio communication protocol that was created as a wireless alternative to the protocol. Today, this technology is popular in connecting two or more mobile devices, particularly smartphones, tablets and laptop computers. We’ll be using the, a widely available and cheap bluetooth device that is capable of going into master (initiator) or slave (acceptor) device. There is another bluetooth module, the HC-06, which looks exactly like the HC-05. The primary difference between the two is that the HC-06 is a slave only device.
Here’s what my HC-05 module looks like: Your device might have the KEY pin instead of the EN pin. The HC-05 module has two modes: Data and Command mode. When in data mode, the module acts as a wireless bridge between two devices. The module is in data mode by default. The KEY pin, when pulled high (connected to 3.3V), is used to allow the HC-05 to enter AT Command mode.
AT commands are used to configure the module. We will discuss these commands later. For my device, AT Command mode is entered by keeping the button pressed and then powering up the module. There is still a KEY pin on my version but not readily accessible: The EN pin, when pulled low (connected to ground), disables the module. The STATE pin is used to indicate connection status: it’s high when the module is connected to a device and low if not. AT Command Mode As mentioned, we enter command mode by either connecting the KEY to VCC or keeping the button pressed while powering on.
The status LED will stay on for 1 second and stay off for another second if in AT Command mode. AT - test the connection. The module should respond with “OK” AT+UART - see the baud rate, stop bit and parity bit. This specifies the baud rate used in command mode. AT+UART= to set a new baud rate.
The baud rate can be 1200, 2400, 4800, 9600, 19200, 38400, 57600 or 115200 AT+PSWD - view pin or AT+PSWD= to set a new pin AT+ADDR - view device’s MAC address AT+ROLE - view role (0 for slave, 1 for master). AT+ROLE= to set new role. AT+ORGL - restore factory settings AT+VERSION - view device version AT+STATE - view device state AT+CMODE - set/view connection mode. 0 to connect the device to a specific address using AT+BIND. 1 to connect the device to any address. AT+BIND= - connect the device to a specific bluetooth address after AT+CMODE = 0.
View the module. Control a LED via Bluetooth and Android We don’t need to use AT commands to control a LED via bluetooth. We simply need to put the HC-05 module back to command mode and start sending data through it. If your device is still in command mode, just remove the power and place it back. The device’s status LED will now start blinking rapidly to indicate that it is unconnected. Next, we’ll need an Android app that can send serial commands via Bluetooth. Sadly, there’s no such option for iPhone/iPad users because Apple requires every device to be accredited first before being usable and HC-05 is not accredited.
You'll need a to work with iOS devices. I’ll write a separate tutorial for that in the nearest future. There are a number of bluetooth terminal application for android. Connect the app to the HC-05 module. The module’s status LED should now be steadily on. Now we will write a sketch that accepts a character from the serial port (where the HC-05 is connected) and change the state of the LED based on that character. We will have a different wiring diagram for this one: I went away from the hardware tx and rx pin so that we can still use the serial monitor for debugging.
