The micro:bit app is the essential companion to the BBC micro:bit, the pocket sized programmable computer. The app allows you to flash any micro:bit hex file to your device, as well as including online access to the Microsoft MakeCode editor for simple block-based programming. When your program is ready, the app beams it to the micro:bit via Bluetooth wirelessly. Easy-to-follow screens lead you through the process of pairing your iPad (or iPhone) to the micro:bit and then transferring your program code. Compared with previous versions, the micro:bit app Version 3.1 contains these additional features: • A simpler pairing and micro:bit discovery flow • The micro:bit V2 can be put into pairing mode by triple-tapping the reset button • Retrieval of the micro:bit data log files from off your micro:bit • Pair with any number of micro:bits • Choose which micro:bit is currently connected • Store HEX files in the app • Choose a HEX file for flashing • Export and delete HEX files • Import stored HEX files directly into JavaScript Blocks editor • Rapid download from JavaScript Blocks editor • Monitor data detected by micro:bit sensors • Use the range of micro:bit Bluetooth services in real time • Display messages on the micro:bit LEDs • Send control commands to the micro:bit buttons and pins • De-bug your program code while it is running in the micro:bit • Use a simulated gamepad to send commands to the micro:bit • View camera images ready for taking photos or video As well as providing more flexible handling of your program scripts and HEX files, a major addition in Version 3 is the Monitor and Control page. This lets you observe real-time data from the micro:bit sensors, send messages directly to the LEDs and control the micro:bit buttons and pins from your iPad or iPhone. Monitor is ideal for exploiting Bluetooth services in real time, and for de-bugging your program code while it is running in the micro:bit. The MakeCode code editor now requires iOS 13 or later.
