Question

I use gradle to upload tests on Arduino (a microcontoller). I can get the test output (on my ubuntu) through /dev/ttyUSB0.

I am looking now for the easiest way to get the test output in gradle. I have made some experiments with cat (ant.exec):

def checkTestResults = {
    ant.exec(
        outputproperty:"cmdOut",
        errorproperty: "cmdErr",
        resultproperty: "cmdExit",
        failonerror:"true",
        dir: './MyArduinoTests',
        searchpath:"true",
        executable: 'cat') {    
            arg(value:"/dev/ttyUSB0")
        }
        println ant.cmdOut  
}

It does not work very well. I do not get the complete output of the serial port. Sometimes, I do not get any output.

How to accomplish this task without writing a separate program that reads the port?

Answer 1

The solution was to write a separate program that reads the port. My colleague wrote simply 8 line of python code.
