Try the following steps to connect to your Micro:bit:
1. You may need to reload this page and try your program again.
2. Try disconnecting and reconnecting your Micro:bit. Then reload the page and run your program again.
3. If you are still having problems your Micro:bit may have an old
firmware version that is incompatible with Codesters.
To update the firmware follow these instructions from Micro:bit
Are you already running a Codesters project in another tab or window?
Micro:bit can only connect to one web page at a time.
Try stopping other Codesters projects or closing
other tabs or windows that may be using your Micro:bit.
If that doesn't fix the problem try disconnecting your Micro:bit,
reloading this page, and reconnecting your Micro:bit.
