Hc06 datasheet

The HC-06 is a Bluetooth module that provides a wireless communication link between two devices. It is commonly used in a variety of projects such as robotics, home automation, and remote control applications. Here is a brief overview of the HC-06 module’s specifications:

  • Bluetooth version: Bluetooth 2.0 + EDR (Enhanced Data Rate)
  • Frequency range: 2.4GHz ISM band
  • Communication range: Up to 10 meters (class 2)
  • Operating voltage: 3.3V DC
  • Operating current: ~30mA (when connected)
  • Standby current: ~0.5mA
  • Serial communication baud rate: 9600bps
  • Default pairing code: “1234”
  • Dimensions: 28mm x 15mm x 2.35mm

The HC-06 module is configured using AT commands, which allow you to modify various settings such as the baud rate, Bluetooth name, and pairing code. The module can be easily interfaced with a microcontroller or a computer using a serial interface. When the module is powered on, it enters into the AT command mode, which allows you to configure the module.

For more detailed information, you can refer to the HC-06 datasheet provided by the manufacturer. The datasheet includes detailed specifications, pinout diagram, AT command set, and application circuits. You can find the datasheet by searching for “HC-06 datasheet” on your preferred search engine.

Modify the hc 05 bluetooth module defaults using AT commands

Sure! Here’s a step-by-step guide on how to modify the HC-05 Bluetooth module defaults using AT commands:

  1. Connect your HC-05 Bluetooth module to your computer via a USB-to-serial adapter. Make sure that the adapter’s TX pin is connected to the HC-05’s RX pin, and vice versa. You should also connect the adapter’s ground pin to the HC-05’s ground pin.

  2. Open a serial terminal program on your computer, such as PuTTY or Tera Term. Set the terminal’s baud rate to 38400 baud and ensure that the terminal is configured to send and receive data via the correct serial port.

  3. Type “AT” into the terminal and press Enter. The HC-05 should respond with “OK”. If you don’t see this response, check your wiring and ensure that the terminal settings are correct.

  4. Now you can start sending AT commands to the HC-05. Here are some of the most common AT commands for modifying the module’s settings:

  • “AT+NAME=<name>” – Sets the module’s name to the specified value (up to 20 characters).
  • “AT+ROLE=<0 or 1>” – Sets the module’s role as either master (0) or slave (1).
  • “AT+PSWD=<pass>” – Sets the module’s pairing password to the specified value (up to 16 characters).
  • “AT+UART=<baud>,<stop>,<parity>” – Sets the module’s UART settings to the specified values. Baud rate can be set to 1200, 2400, 4800, 9600, 19200, 38400, 57600, or 115200. Stop bits can be set to 1 or 2, and parity can be set to N (none), E (even), or O (odd).
  1. After sending an AT command, the HC-05 should respond with “OK” if the command was successful. If the command was not successful, the module will respond with an error message starting with “ERROR:”.

  2. To save your changes, you need to enter the “AT+RESET” command to reset the module. This will cause the HC-05 to restart with the new settings applied.

That’s it! With these commands, you can modify the HC-05 Bluetooth module defaults to suit your needs. Just remember to always send the “AT+RESET” command after making changes to ensure that your modifications are saved.
