  1. Hello Together
    Do you have a plan of this module how it exactly works, like which are the output input ports etc.?
    and can you say me in which class this module sends 1, 2 or 3?
    Would be really nice because i just do a school project about your mbot and i have to analyze the bluetooth sensor.
    Thanks in advance.
    (sorry for my bad english (CH))

    1. Hi Benjamin,

      The Bluetooth module is just a serial passthrough device once working.
      Once it is powered on, it starts flash and directly enter the pass through, you can use Bluetooth to directly search for connections. No code processing is required.

  2. I have 5 mBots all with Bluetooth and would like to use them together in a classroom setting. Can you pair each Bluetooth module to a separate Bluetooth equipped device “smartphone” and run them all at the same time?

  3. Hi,
    I have 2pcs of “Bluetooth Module for mBot” but don’t have Me Bluetooth Module (RJ25).
    My question is:

    Can I connect “Bluetooth Module for mBot” with “RJ25 to Dupont Wire” directly to “Me UNO Shield” Port5 (RJ25 serial port),

    or I need to use 5v to 3.3v bidirectional level converter (for RX and TX) and then connect to “Me UNO Shield” Port5?
    sorry for my bad english.

    1. Hi Mario,

      The Bluetooth Module for mBot is different with Me Bluetooth Module.
      It won’t work with the Mu Uno Shield.

  4. I’m making a Robot controlled by smartphone via Bluetooth. But any one can connect my Robot and control it. Its very dangerous. So how can I add an connect verify? Add a password or Get the phone’s Bluetooth MAC address?

    1. Hi Harvey,

      I am afraid the Me Bluetooth module can’t be set a password and get the phone’s Bluetooth MAC address.
