BLE Keywords and intro:
1. Unable to connect with Bluetooth classic
2. Central/Periphral
3. Service/Characteristic
4. Advertise/Scanning

Bord selection :
Nano BLE 33 rev2(Periphral) <--> Nano IOT 33(Central)
callIMU.ino <-> periphralexploere.ino

## Begeiner project :
Periphral post IMU data (advertise service)on bulletin for Central reading

### Structure
How to post IMU Data

1. Set periphiral device name
2. Create Service ex: IMU
3. Create Characteristic ex: ax/ay/az
4. Advertised Service
5. add Characteristic
6. add Service
7. advertise service
8. write Value


#### !! characteristic.uuid() >> return as a string

!!String a = characteristic.uuid();

void exploreCharacteristic(BLECharacteristic characteristic) {
  // print the UUID and properties of the characteristic
  Serial.print("\tCharacteristic ");
  Serial.print(characteristic.uuid());
  "String a = characteristic.uuid();"
  // check if the characteristic is readable
  if (characteristic.canRead()) {
    // read the characteristic value
    characteristic.read();
    if (characteristic.valueLength() > 0) {
      // print out the value of the characteristic
      //Serial.print(characteristic.local());
      Serial.print(", value : ");
      if((a=="0056"||a=="0055"||a=="0057")){
      printCharacteristic(characteristic.value(), characteristic.valueLength());
      //Serial.print('C');
      }else{
        printData(characteristic.value(), characteristic.valueLength());
        //Serial1.println('G');
      }
      //printCharacteristic(characteristic.value(), characteristic.valueLength());//chara only
      //Serial1.println(characteristic.value());
    }
  }
  Serial.println();
  // loop the descriptors of the characteristic and explore each
 /* for (int i = 0; i < characteristic.descriptorCount(); i++) {
    BLEDescriptor descriptor = characteristic.descriptor(i);
    exploreDescriptor(descriptor);
  }*/
