Customer Notice (New Bluetooth App):
We have recently produced a new Google Play Store app called Kitronik Bluetooth Control. This Android app allows you to control a Kitronik Kitronik :MOVE mini buggy over Bluetooth. The new Kitronik Bluetooth Control app replaces our previous Android app that features in this resource. We suggest that you switch to this new app for a better and more consistent experience. See the links below for more details.
This Resource:You’ll be pleased to note that all of the hard work has now been done, we now have a fully customised line following buggy and the BBC micro:bit has been flashed with the code that it needs to unlock the magic of Bluetooth. Bluetooth is the technology that makes the remote control aspect of this project possible, fortunately, the BBC micro:bit comes with Bluetooth functionality as standard, which just leaves two steps; pairing the BBC micro:bit with your Android device and installing Martin Woolley’s micro:bit Blue Android App for the BBC micro:bit. We'll hand over to Martin Woolley, the author of the App, to explain how it's done.
Obtaining and installing the application:To use the micro:bit Blue application, you’ll need an *Android smartphone or tablet. Android version 5 or 6 is recommended but micro:bit Blue may work on some devices which run version 4.4 too. (* If you only have an Apple handheld device, don't despair. Martin Woolley’s micro:bit Blue Android App for the BBC micro:bit is coming to Apple soon. More details to follow.) Install the application direct from the Google Play app store on your Android device. You can download micro:bit Blue here.
Pairing An Android Phone To The BBC micro:bit:Bluetooth has a concept called ‘pairing’. Pairing is something you have to do so that two devices which will want to communicate using Bluetooth can trust each other and work securely. micro:bit usually needs to be paired with a smartphone before it can be used. One of the benefits of using pairing with the micro:bit is that only you can control your Kitronik buggy because your micro:bit will only trust phones or tablets it has been paired with. You wouldn’t want somebody else taking control of your buggy from their phone and driving off with it, would you? How to pair your micro:bit is best demonstrated rather than explained. Here’s a video from Martin’s blog which shows how to pair a BBC micro:bit with an Android phone:
Using micro:bit Blue:After pairing, launch micro:bit Blue on your Android device. On the first screen, tap the ‘FIND PAIRED BBC MICRO:BIT(S)’ button to cause your phone to scan for your micro:bit. If there are several micro:bits nearby, you should still only see yours since the application will filter out micro:bits which you have not paired with. Tap the line which contains your micro:bit as shown in the screenshot above. This will cause your phone to connect to your micro:bit. You should see a letter “C” appear on the micro:bit display at this point. The next screen is a menu of things that micro:bit Blue can do (you’ll need the right code on your micro:bit to use the various options). Swipe up and scroll the menu until you can see the Dual D-Pad Controller menu item. Select it and you’ll find yourself looking at the game controller screen we’ve already seen! Have fun driving!
