I’ve mentored my eldest daughter and her friends for the creation of a robot dance performance using Lego EV3 bricks. For this they used Bluetooth extensively (check it out here if you are interested: https://www.youtube.com/watch?v=xpWPyyBr4Co). This allowed for great interaction between the robots but EV3s are not cheap. For the future, I wanted to include more affordable robots whilst still being able to get the robots to interact.
I’ve bought a couple of mBots (v1.1 Bluetooth) and am wanting to investigate connecting from a Lego EV3 to an mBot (or mBots if possible) via Bluetooth and then communicating simple messages between them.
I’ve seen this to give me hope:
From an EV3, if I look for Bluetooth connections, I can see the mBot (named ‘Makeblock’). When I try to connect it to (using blank or default 1234 passkey), it hangs. Any tips? If I can get past the connection, I then need to work out how to send messages EV3 -> mBot and vice versa so they can be interpreted on the other side. Any help is appreciated.
