Your own MakeCode project (No pairing required)

You can create a Bluetooth-enabled MakeCode project yourself. Below are the detailed instructions to create a micro:bit MakeCode project, enable the Bluetooth extension and disable pairing. A project with pairing disabled ("No pairing required") is the easiest to work with:

• it works on the widest range of micro:bit versions and operating systems
• it doesn't require the extra steps of pairing the micro:bit with your operating system
• it makes the microbit advertise its name, so you can find it by name

The disadvantage is that anyone can connect with the micro:bit over Bluetooth, because it is not needed to be paired to it.

Create a project

In MakeCode for micro:bit, select "New Project"

Enter a name:

Add the Bluetooth extension

You'll need to add the Bluetooth extension.
Select "Advanced"

Select "Extensions"

Search for Bluetooth, and select the Bluetooth extension

A popup appears, informing you that the "radio" extension will be removed if you add Bluetooth. Select "Remove extension and add Bluetooth", this will only apply to this project.

Disable pairing

In the top-right corner click on the cog icon and select project settings. Enable the "No pairing required: anyone can connect via Bluetooth" option. Save the Settings.

Add Bluetooth services

Now you can select blocks from the bluetooth tab:

Drag the services you want to enable in an "On start" block

The micro:bit v1 has too little memory to enable all bluetooth services. If you try to enable them all, after copying the hex the micro:bit, the LED display wil show a sad face and then scroll 020, this means the micro:bit is out of memory. See also: the micro:bit error codes
