Communicate via Bluetooth

Hardware Arduino 101
5

Thank for your help.

Since the Arduino 101 only can act as a Slave i have two options

  1. Control every thing with my iPhone 5.
    I was able to write some code, so the Motor will turn on if i connect to the Arduino. this is fine. But i also would like to set the speed of the Motor with my iPhone. I did not manage to do this until now. When i connect to the Arduino with the iPhone i can only send some 0x.... commands and do not know what his means?!?

How can i send some values to the Arduino with an app? Do you know some good apps? How do i have to write the code?

------- With this i would like to define the Services and Characteristics:------

BLEPeripheral blePeripheral; // create peripheral instance

// Neuer Service für die Kommandos des anderen Arduinos
BLEService firstService("19B10000-E8F2-537E-4F6C-D104768A1214"); // create service
BLECharCharacteristic commands("19B1001-E8F2-537E-4F6C-D104768A1214", BLERead | BLEWrite | BLENotify); // create switch characteristic and allow remote device to read and write
BLEIntCharacteristic v("19B10002-E8F2-537E-4F6C-D104768A1214", BLERead | BLEWrite | BLENotify); // Geschwindigkeit

------- And these are the Callbacks i would like to make: ----------

// assign event handlers for connected, disconnected to peripheral
blePeripheral.setEventHandler(BLEConnected, blePeripheralConnectHandler); // je zwei CALLBACKS
blePeripheral.setEventHandler(BLEDisconnected, blePeripheralDisconnectHandler);

// assign event handlers for characteristic
commands.setEventHandler(BLEWritten, SteuerungDerGeschwindigkeit);

------- and the Callbacks defined--------

void blePeripheralConnectHandler(BLECentral& central) {
// central connected event handler
Serial.print("Connected event, central: ");
Serial.println(central.address());

firstMotor->setSpeed(40);
firstMotor->run(FORWARD);

}

void blePeripheralDisconnectHandler(BLECentral& central) {
// central disconnected event handler
Serial.print("Disconnected event, central: ");
Serial.println(central.address());

firstMotor->run(RELEASE);
fitstMotor->setSpeed(0);

}

void SteuerungDerGeschwindigkeit(BLECentral& central, BLECharacteristic& characteristic) {
// central wrote new value to characteristic, update Speed
Serial.print("Characteristic event, written: ");

int i;

if (commands.value() == 0) {
Serial.println("Start the Motor mit der gegebenen Geschwindigkeit");

firstMotor->run(FORWARD);
for (i=0; i<v.value(); i++) {
firstMotor->setSpeed(i);
delay(50);
}

} else {
if (commands.value() == 1) {
Serial.println("Stoppen");

for (i=v.value(); i>0; i--) {
firstMotor->setSpeed(i);
delay(50);
}

}

}

... but a I sad, i can connect to the Arduino with a app, but I can not write values for "commands" and "v"

Alternatively i can also connect with my Mac. Do you know a good software to send some commands?

  1. The other option to make the whole communication with a Seeed BLE Shield v1.1 that i found.

I have a example from http://www.seeedstudio.com/wiki/Seeed_BLE_Shield_v1 but this did not work!!

Is there a special baud rate i have to chose? Or does the Shield can not read the AT commands?

Thanks for your Help.
