Hello everyone, i need help for use bluetooth admin because there are very few people showing how to actually use the blueooth admin component and how to connect with the bluetooth client and admin.
My problem is that i can’t see all the nearby blueooth devices so I have to scan but when the time comes to connect to them I don’t know what to do and I can’t arrive so thank you in advance for your help !!! :slight_smile:

No, the problem is that i can’t see every device around me so i can’t connect to the arduino so i have to use bluetooth admin to scan the devices around but then I can’t connect to the devices so I just need an example of a functional application with it all.

Hello everyone, I forgot to tell you that I managed to make a list where I see the various devices but I cannot connect to it.

Arduino must be paired with phone before trying to connect with app

I want to remember that my bluetooth module that I use is a BLE module but no matter which application I use nothing works.

Can you please tell me what you want to control using Bluetooth.
if you need to control relays then use Bluetooth client (Available in connectivity)
or check out this my working AIA

Node_MCU_Remote.aia (2.7 KB)

Arduino code

char Data = 0;

void setup() {
Serial.begin(9600);
pinMode(13, OUTPUT);
}

void loop() {
if (Serial.available()) {
Data = Serial.read();

}
if (Data == ‘A’) {
digitalWrite(13, HIGH);

}
if (Data == ‘B’) {
digitalWrite(13, LOW);

}

}
