Connecting Arduino Nano 33 to smartphone

Your topic has been moved to a more suitable location on the forum. Installation and Troubleshooting is not for advice on (nor for problems with) your project. See About the Installation & Troubleshooting category.

There is no Nano 33, there are Nano 33 BLE, Nano 33 BLE Sense and Nano 33 IoT. Feel free to move your topic to one of these dedicated categories yourself if needed.
