    Hello,

    Normally we use hc-05 with our arduino to accept bt commands sent by our phone to make arduino do things. Is the opposite possible: Can we use hc-05 to connect to another device that has bluetooth : for example : an electric scooter and use their bt protocol to control them ?

    Thanks

    HC05 is a Slave BT device, meaning it can only accept connection requests.
    This means that with HC05, the Arduino is NOT the one initiating the connection.
    You should use the HC06 module, which can be both Master and Slave, thus having the ability to search and request connection to other BL devices.

    [IMPORTANT EDIT]

    Apparently I have inverted the master/slave module names...
    The HC05 IS MASTER/SLAVE CAPABLE
    The HC06 IS ONLY SLAVE CAPABLE

    Sorry, my first reply was while working, and when I got home I went browsing to be sure...

    No problem, an additional module won't hurt:) thanks.
