How do I use the HC-06 Bluetooth module?

How do I use the HC-06 Bluetooth module?

Tap the HC06 in the list, and you will then be asked for the PIN – it is 1234. Finally, open your terminal app on the smartphone, and select “Connect a device” from the app menu. Select the HC-06 option and then wait a moment. The LED on the Bluetooth module should stay on and the app will show “connected: HC-06” .

Can we use Bluetooth module without microcontroller?

Long answer: most Bluetooth modules are connected to host (microcontroller, processor, etc.) over UART (Serial) connection. So they can’t work without a microcontroller. Also, there are few microcontrollers with integrated Bluetooth and WiFi, such as ESP32, but they are just MCU and Bluetooth module in one IC.

How do I pair my phone with a HC-05 Bluetooth module?

Follow these mini-steps:

  1. Connect the Rx and Tx pins of HC-05 back to Arduino (if you haven’t did this already).
  2. Pair the device with your mobile phone (in my case I am using Android OS and my phone is Samsung SII).
  3. Download “Bluetooth Terminal” app from Google Play Store.
  4. Open Bluetooth Terminal app.

How to connect hc06 Bluetooth to an Arduino?

The LED on the Bluetooth module should stay on and the app will show “connected: HC-06” . Now send the number 1 through the terminal and the onboard LED on the Arduino should turn on. Send 2 and it should turn off.

How to connect hc06 Bluetooth to serial wireless UART?

Select the HC-06 option and then wait a moment. The LED on the Bluetooth module should stay on and the app will show “connected: HC-06” . Now send the number 1 through the terminal and the onboard LED on the Arduino should turn on. Send 2 and it should turn off.

How does the Android app connect to the Arduino module?

The Android app is designed to send serial data to the Arduino Bluetooth module when a button is pressed on the app. The Arduino Bluetooth module at other end receives the data and sends it to the Arduino through the TX pin of the Bluetooth module (connected to RX pin of Arduino).

Is the module hc-06 powered but not paired?

To allow configuration, the module HC-06 should be powered but not paired (la LED is blinking). The following code allows you to modify the parameters using the serial monitor. To test serial communication, enter AT in the serial monitor and click on the send or press enter.
