    • Q
    • Does HC-05 Bluetooth Module has KEY pin?

      asked by GlennShose on July 14, 2017
    • A
    • Yes, it has key pin and can be used to bring in the AT mode and pairing mode.

    • Q
    • can we interfacing it with Arduino Pro Mini?

      asked by Abhishek Anand on August 24, 2016
    • A
    • There are two versions of Arduino Pro Mini. One runs at 3.3V,8 MHz, the other at 5V,16 MHz. I/O Pins of HC-05 Bluetooth Module are not 5V Tolerant , use level converter for interfacing with 5V Pro Mini and can plug directly with 3.3V Pro Mini.
      The HC-05 Bluelink 5V TTL is a breakout board from rhydoLABZ based on HC-05 bluetooth module which gives 5V TTL output which can directly plug with 5V Pro Mini.

    • Q
    • How can Master Slave communication done with these module?

      asked by Parth Lakhiya on September 06, 2016
    • A
    • To establish communication between two Bluetooth modules, configure one as master and other as slave using AT command. The master establishes connection with slave devices found within its range.

    • Q
    • Is this module with base board or without base board?

      asked by Sagar Gondge on April 24, 2017
    • A
    • This module doesn't comes with base board. This is only the bluetooth module. But we have another HC-05 module comes with breakout board which is HC-05 Bluelink 5V TTL, rhydoLABZ part number is WRL-2509. Here is the link
