How to use the hc-05 in command mode with Arduino?

To solve this, wire pin 34 of the IC to 3.3 V: The HC-05 is now in command mode if the red LED flashes once every two seconds. The following commands require that the HC-05 is connected to the Arduino as a serial device. Below is an example wiring diagram and sketch/code:

How to send data from HC05 to Arduino via Bluetooth?

Sending Data to Arduino via Bluetooth. HC05 module has an internal 3.3v regulator and that is why you can connect it to 5v voltage. But we strongly recommend 3.3V voltage, since the logic of HC05 serial communication pins is 3.3V.

What is the hc-05 Bluetooth module?

The HC-05 is a common Bluetooth module used in many microcontroller projects. Here’s a compilation of all HC-05 Bluetooth AT Commands. For beginners, see Arduino Bluetooth. By default, the HC-05 is configured in data mode. In this mode, the module acts like a serial bridge.

What are the AT commands available on the hc-05?

The HC-05 comes with a rich set of AT commands to perform various tasks such as changing the module’s default settings including changing the pass code and the device name. It has got one LED, Which shows its state. If it is blinking that means it is not connected. If it is staying in glowing condition that means it is connected.
