Hello Arduino~
I try to use BLE to send data from arduino101 to another
so I refer to the heart rate monitor sample code
My code looks like this
#include <CurieBLE.h>
BLEPeripheral blePeripheral; // BLE Peripheral Device (the board you're programming)
BLEService heartRateService("180D"); // BLE Heart Rate Service
// BLE Heart Rate Measurement Characteristic"
BLECharacteristic heartRateChar("2A37", // standard 16-bit characteristic UUID
BLERead | BLENotify, 2); // remote clients will be able to get notifications if this characteristic changes
// the characteristic is 2 bytes long as the first field needs to be "Flags" as per BLE specifications
// https://developer.bluetooth.org/gatt/characteristics/Pages/CharacteristicViewer.aspx?u=org.bluetooth.characteristic.heart_rate_measurement.xml
int heartRate = 0;
int oldHeartRate = 0; // last heart rate reading from analog input
long previousMillis = 0; // last time the heart rate was checked, in ms
int PIN = 3; // 3번핀은 오른쪽과 동시에 되므로 오른쪽 키를 사용하지 말
int PIN_BUTTON_UP = 2;
int PIN_BUTTON_LEFT = 5;
int PIN_ANALOG_X = 0;
int PIN_ANALOG_Y = 1;
int button[] = {2,5};
int *pX;
int *pY;
void setup() {
Serial.begin(9600); // initialize serial communication
pinMode(13, OUTPUT); // initialize the LED on pin 13 to indicate when a central is connected
/* Set a local name for the BLE device
This name will appear in advertising packets
and can be used by remote devices to identify this BLE device
The name can be changed but maybe be truncated based on space left in advertisement packet */
blePeripheral.setLocalName("Controller");
blePeripheral.setAdvertisedServiceUuid(heartRateService.uuid()); // add the service UUID
blePeripheral.addAttribute(heartRateService); // Add the BLE Heart Rate service
blePeripheral.addAttribute(heartRateChar); // add the Heart Rate Measurement characteristic
/* Now activate the BLE device. It will start continuously transmitting BLE
advertising packets and will be visible to remote BLE central devices
until it receives a new connection */
blePeripheral.begin();
Serial.println("Bluetooth device active, waiting for connections...");
for(int i = 0; i < 2; i++){pinMode(button[i], INPUT_PULLUP);}
}
void loop() {
// listen for BLE peripherals to connect:
int UP = digitalRead(PIN_BUTTON_UP);
int LEFT = digitalRead(PIN_BUTTON_LEFT);
int X = analogRead(PIN_ANALOG_X);
int Y = analogRead(PIN_ANALOG_Y);
pX = &X;
pY = &Y;
BLECentral central = blePeripheral.central();
// if a central is connected to peripheral:
if (central) {
Serial.print("Connected to central: ");
// print the central's MAC address:
Serial.println(central.address());
// turn on the LED to indicate the connection:
digitalWrite(13, HIGH);
// check the heart rate measurement every 200ms
// as long as the central is still connected:
while (central.connected()) {
long currentMillis = millis();
// if 200ms have passed, check the heart rate measurement:
if (currentMillis - previousMillis >= 200) {
previousMillis = currentMillis;
updateHeartRate();
}
}
// when the central disconnects, turn off the LED:
digitalWrite(13, LOW);
Serial.print("Disconnected from central: ");
Serial.println(central.address());
}
}
void updateHeartRate() {
heartRate = controller(*pX,*pY);
if(heartRate != oldHeartRate)
{ // if the heart rate has changed
Serial.print("Heart Rate is now: "); // print it
Serial.println(heartRate);
const unsigned char heartRateCharArray[2] = { 0, (char)heartRate };
heartRateChar.setValue(heartRateCharArray, 2); // and update the heart rate measurement characteristic
oldHeartRate = heartRate; // save the level for next comparison
}
}

well My code is not very well made code
full of errors, but it compiled anyway
I use joystick shield and read the data from that
and send specific data to another via BLE
return to the topic
when I upload this and connect to android nRF toolbox applications
nothing shows in graph
why this happens?
because this service just read analog sample?
If I want to send data like this which service is fit to me?
please help me :o
