Not able to send / Receive data using HC-05 Bluetooth module

[sarkarstanmoy]

Hi,

I have followed https://github.com/rwaldron/johnny-five/wiki/Getting-Started-with-Johnny-Five-and-HC-05-Bluetooth-Serial-Port-Module and able to configure bluetooth module. I have also followed node-serial https://github.com/voodootikigod/node-serialport and use below code

var SerialPort = require("serialport").SerialPort
var serialPort = new SerialPort("COM3", {
  baudRate: 57600 ,
        dataBits: 8,
        parity: 'none',
        stopBits: 1,
        //parser: SerialPort.parsers.readline("\n"),
        flowControl: false
}, false); // this is the openImmediately flag [default is true]

serialPort.open(function (error) {
  if ( error ) {
    console.log('failed to open: '+error);
  } else {
    console.log('open');
    serialPort.on('data', function(data) {
      console.log('data received: ' + data);
    });
    serialPort.write("ls\n", function(err, results) {
      console.log('err ' + err);
      console.log('results ' + results);
    });
  }
});

and got below output

open
err undefined
results 3
data received: ��yStandardFirmata.ino�

But when I connected to Bluetooth using BlueTerm app in my android phone and try to send data nothing is displayed on console. Can you please help me on this. I have also followed #165 issue but still not able to figure out the solution. Request you to kindly help me on this.

Any update on this issue

First of all, the issue you are experiencing appears to be related to node-serialport, not johnny-five. It may be helpful to open this issue for that project.

You are receiving the REPORT_FIRMWARE query results upon establishing the serial connection as expected: ����y��StandardFirmata.ino�, the console just isn't printing the non ascii characters. However, I'm not sure why you're getting the error on serial write.

Thanks for the reply. As you have suggested I will raise this issue to node-serialport team.
