BT communication with Android Phone

I need help from the community to know if the Nano 33 BLE can be set as master to communicate with a slave android phone.
If someone as a little sketch/instruction to set it ...... would be very useful.
Thank You

Hi technihaus,

You will need to install the ArduinoBLE library.

Here you will find the examples:

By the way... the "Master" is called central and "Slave" is called peripheral by BLE.
