When trying to create an iOS Shortcut which calls an MMI code, such as the forwarding interrogation code *#21#, you may find that Shortcuts refuses to place the call and shows the error message MMI or SSD is not supported.

You can work around this in some circumstances by opening a tel: URL to the MMI code. To do so:

1. Create an action to "Open URLs"
2. For the URL, enter tel: followed by the MMI code you want to dial, replacing * (asterisk) with %2a and # (pound sign) with %23

To dial *#21#, your shortcut action would say the following:

Open tel:%2a%2321%23

ESP32 as Bluetooth Keyboard

With its built-in Bluetooth capabilities, the ESP32 can act as a Bluetooth keyboard. The below code is a minimal example of how to achieve it. It will generate the key strokes for a message whenever a button attached to the ESP32 is pressed.

For the example setup, a momentary button should be connected to pin 2 and to ground. Pin 2 will be configured as an input with pull-up.

In order to receive the message, add the ESP32 as a Bluetooth keyboard of your computer or mobile phone:

1. Go to your computers/phones settings
2. Ensure Bluetooth is turned on
