Although the Lesser General Public License is Less protective of the users' freedom, it does ensure that the user of a program that is linked with the Library has the freedom and the wherewithal to run that program using a modified version of the Library. The precise terms and conditions ...
Everything between the two curly brackets or braces after 'void setup()' is the code that executes during the setup. Make sure you always close your brackets, otherwise, you'll get strange errors. The IDE helps you with this by highlighting the other bracket, if you select one. ...
You can add an else statement after this: if (message ==”led_on”){ digitalWrite(ledPin, HIGH); } else if (message ==”led_off”){ digitalWrite(ledPin, LOW); } for example: else{ SerialBT.print(“Invalid message”); } If the message is not “led_on” or “led_off”, it ...
With Bluetooth Low Energy, there are two types of devices: the server and the client. The ESP32 can act either as a client or as a server. The server advertises its existence, so it can be found by other devices, and contains the data that the client can read. The client scans the...
