5 years ago I think that a test is missing if Serial.available (), but it should still work because the read () function is non-blocking and returns -1 if nothing is available. Are you sure you have configured the serial port correctly (by default it is used to display kernel messages): https://www.raspberrypi.org/documentation/configuration/uart.md The first thing to do is to watch with minicom if you receive the serial port information ... With Codelite you can put a breakpoint and see what your program does. Could you copy me the result of pinfo?

Hi, I created a sample bluetooth controlled led using piduino library. Below is the code is executed. How can I include rfcomm in the below code ? I am able to run the code, but not able to control the LED using android via bluetooth.
include
int led = 21; int data = 0;
void setup()
{
pinMode(led, OUTPUT); Serial.begin(9600);
}
void loop() {
data = Serial.read(); if(data == '1') { digitalWrite(led, HIGH); }
if(data == '0') { digitalWrite(led, LOW); }
}
