What does ‘Pair’ mean?
The Bluetooth wireless communication between your iPhone or iPad and the micro:bit requires the sending and receiving devices to identify and recognise each other. ‘Pairing’ is the process of doing this through the exchange of digital signals. It’s a bit like looking for and exchanging telephone numbers; once done, your iPad knows where to find your micro:bit, and the micro:bit knows how to find your iPad.
When do ‘paired’ micro:bits need to be ‘forgotten’?
Normally, your iPad or iPhone will remember a paired micro:bit after switching off. However, sometimes the use of the micro:bit causes it to forget that it is paired with your iPad or iPhone. This may happen if it is paired with several iPads or its memory has become cleared. When the micro:bit forgets a pairing, the app is likely to show an error message with the advice for the iPad to ‘forget’ the micro:bit also. You can do this from Settings in the Bluetooth section which shows a list of paired devices. For your micro:bit, tap and select Forget This Device..
How do I find out the [name] of a micro:bit?
Each micro:bit has a special name of five letters related to the LED pattern which appears during pairing. After pairing with a micro:bit, its name is shown in square brackets on the Connection and Flash pages.
What does ‘Flash’ mean?
‘Flashing’ is when you send a .HEX code file to the micro:bit. The code gets stored in flash memory in one of the chips on the micro:bit, overwriting the previous code. This app uses Bluetooth wireless to send the file. From a computer, a file is usually flashed by connecting a USB cable to the micro:bit.
What happens to pairing if I flash a file using a USB cable?
It is possible that the use of USB to flash a file causes the micro:bit to forget pairing, in which case follow the instructions for making your iPad or iPhone to forget the micro:bit also. Then start pairing again.
How do I make sure that the micro:bit contains the latest software?
