The program is transmitted via Bluetooth and deletes the previous script, but not the firmware of the mini. The last transferred program is always executed.

If you use MakeCode for programming, you can define the connection settings yourself. We have set "No connection required" as default. This provides the simplest connection between a device and a Calliope mini. If you are using different devices and you want to change minis, you should finally play the demo program from the app on the mini. This way you can easily connect to the mini with any other device next time. Otherwise the ID pattern will not appear!
Why is pairing important? Well, this pairing is all about the wireless connection between Calliope mini and smartphone/tablet/computer. By connecting the smartphone to the Calliope mini, you can ensure that these devices can communicate with each other.

To use the Calliope mini with Bluetooth, you need the latest firmware. The current firmware is characterized by the demo sequence with steps 1-5.
If you have a different start sequence, there are two ways to transfer the latest version:
connect the Calliope mini to your computer via a USB cable.
download the latest firmware here.
copy the HEX file into the "MINI" drive
the Calliope mini must be connected to the app.
select demo program (under iOS at "Your Programs", under Android at "Start Program").
the program is transferred and the Calliope mini restarts. When Reset is pressed, the Calliope mini starts with the demo program.
The connection is interrupted
If the app does not jump into the transfer phase, the connection is interrupted.
To re-establish this connection, the app must be closed and reopened. The connection is automatically re-established. Now applications can be transferred again.
The screen stops at "Initialize "
If the transfer does not start and the Initialize screen appears, the Calliope mini must be removed in the Bluetooth settings of your device. You will find detailed instructions on how to do this in the Tips section below.
The Playgrounds lesson does not update itself
To reconnect or in case of unwanted behavior within a Playgrounds lesson, you can jump to the previous lesson and then switch back to the desired lesson. Now the memory should be free and a connection should be possible again.

Default settings in the editor
If you use MakeCode for programming, you can define the connection settings yourself. We have set "No connection required" as default. This provides the simplest connection between a device and a Calliope mini. If you are using different devices and you want to change minis as well, you should finally play the demo program from the app on the mini. This way you can easily connect to the mini with any other device next time. Otherwise the ID pattern will not appear!
Occasionally it happens that paired devices get lost. In this case, you will have to search again and reconnect the Calliope mini.
If new code is played on the Calliope mini via a USB cable, the Bluetooth connection data of the Calliope mini will be lost. If new programs are copied to the Calliope mini via a USB cable, the connection must therefore be re-established.
However, if you play a new code on the Calliope mini via Bluetooth, the connection will not be lost.
If you want to reconnect, you must first disconnect the other
device (e.g. smartphone or tablet) can be removed:
Under iOS, this can be done under Settings/Bluetooth, select Calliope mini and then select "Forgot device".
Under Android, you can do this under Settings/Bluetooth, select the gear wheel next to the Calliope mini and then select "FORGOT".
