Connecting to RFdunio

[laurenzrau91]

Hi again,
I´m still having problems to get a working communication from the iphone app to a RFduino.
The code is quite the same as the example code:

Just checking if the touch event is executed:

void ofApp::touchDown(ofTouchEventArgs & touch){
    unsigned char data[3];
    data[0] = '1';
    data[1] = '2';
    data[2] = '3';
    ofxBLESendData(BLEDeviceImpl, &data[0], tx, 3);
     cout << " didSendData " << endl;
}

And connecting to my particular device:

void ofApp::didDiscoverBLEDevice(BLEDevice *device)
{
    cout << " didDiscoverBLEDevice " << endl;
    if(device.name != nil)
    {
        std::string deviceName([device.name UTF8String]);
            cout << deviceName << endl;
      //  cout << device.advertisementRSSI <<endl;

        if(deviceName == "LaurenzRFduino") {
            ofxBLEConnectDevice(device);

        }
    }
}

The connection is working and the touch is executed but no data are recieved on the Arduino end.

Thats the other side:

#include <RFduinoBLE.h>


int testData = 1;
bool didConnect=false;

void setup() {
  Serial.begin(9600);
  RFduinoBLE.deviceName = "LaurenzRFduino";
  RFduinoBLE.advertisementData = "data";
  RFduinoBLE.begin();
 // RFduinoBLE.txPowerLevel = +4;


}

void loop() {
 //RFduinoBLE.sendInt(testData);
}

void RFduinoBLE_onAdvertisement(bool start) {
}

void RFduinoBLE_onConnect(){
Serial.println("Did connect");
 RFduinoBLE.sendInt(testData);
didConnect= true;
}

void RFduinoBLE_onRSSI(int rssi){ 
 Serial.println(rssi); // print rssi value via serial }
}

void RFduinoBLE_onDisconnect(){
Serial.println("Did disconnect");
didConnect= false;
}

void RFduinoBLE_onReceive(char *data, int len)
{
  // display the first recieved byte
  //Serial.println(data[0]);
  //Serial.println(len);
    Serial.println("hello");
    RFduinoBLE.sendInt(testData);
}

Same thing here: The connection works and I do get an RSSI value but no data is recieved nor can I send anything in the other direction.

This looks like it should all be working. I'll set something up here and see what I can figure out.

So sorry to drop the ball on this! Could you put a breakpoint at line 257 of BLEDelegate.mm in the method - (void) send:( unsigned char *) data len:(int)length and let me know what happens in there? I'm wondering if there's problem with the characteristic definitions somehow?
