Hello, I am trying to read data sent by a nRF51822 Bluetooth LE module (Adafruit Feather M0 Bluefruit LE). I modified the bleuart_datamode sketch given as example to send the same data via bluetooth and USB serial. I can see the Bluetooth data on my iPad with the Bluefruit LE connect app so I know that my board is sending stuff in the air. Using processing however I can read the serial data but I get a null string from bluetooth. I suspected a baud rate problem so I tried everything... I don't get any error message though. The code is compiling and running but I get a null string...
Any idea ? Thanks !

int lf = 10; // ASCII linefeed aka '/n'

myFont = loadFont("ArialMT-18.vlw"); // Processing>Tools>Create Font
textFont(myFont, 18);
printArray(Serial.list());
mySerialPort = new Serial(this, Serial.list()[1], 115200);
mySerialPort.bufferUntil(lf);
myBluePort = new Serial(this, Serial.list()[0], 1200);
