Bluetooth ble is used for low energy and that part is always forgotten. I’ve search all over the web and still didn’t find any explanation of how it work. As an example, do you save more power if you read from another device or if it’s written on the Arduino. Another is how ...
The Arduino Nano 33 BLE Sense combines a tiny form factor, different environment sensors, and the possibility to run AI using TinyML and TensorFlow™ Lite. Whether you are looking at creating your first embedded ML application or you want to use Bluetooth® Low Energy to connect your project...
In the Arduino serial monitor, select “Both NL & CR” at the bottom of the window and whatever you type in the serial monitor will be sent to the Android Bluetooth Terminal. If NL&CR are not selected, the Arduino will still send the data but the Bluetooth Terminal program will not dis...
