Nodejs Error "SerialPort is not a function...." with node-serialport-omega2



  • Re: Serial port communication using Node.js

    @Steven-de-Salas Hello I am having some trouble getting the node-serialport-omega2 module to function.

    To isolate the problem I have factory reset my Omega and only installed Nodejs and NPM.

    I downloaded the node_modules from the above link

    https://github.com/sdesalas/robotics/raw/master/omega2/node-serialport-v3.0.0.tar.gz
    

    and SCP'd those files to the Omega.

    Then checked it with npm ls, which reports several missing dependencies. I installed all depenencies until npm ls reports no errors ( Except for a version conflict with debug, however the error states that the serialport module will still load. )

    I have a very minimal script.

    var SerialPort = require('serialport');
    var port = new SerialPort('/dev/ttyS0',
                    {
                            parser: SerialPort.parsers.readline('\n'),
                            baudRate: 115200
                    });
    

    when I run the script I get the following error.

    var port = new SerialPort('/dev/ttyS0',
               ^
    
    TypeError: SerialPort is not a function
    

    If it will be of interest or help I can post my full npm ls here.

    Thank you in advance for your help.
