2. write string & hexString
3. write data and wait response
4. read is not block, you must check read data in you application. include response data.
5. if you recive 2 or more message and do not read in time. you will get all in next read.

API

openDevice

• config
• success callback
• error callback

config:

• dev: serial port device node
• baudrate: serial port baud rate
• flags: srdial port flags
• isHex: if you want to use hexString you should set it to true.

example:

cordova.plugins.SerialPortPlugin.openDevice([{dev:'/dev/ttyS0',baudrate:115200, flags:0, isHex:false}],
    result=>alert(result),
    error=>alert(error));
}

closeDevice

example:

cordova.plugins.SerialPortPlugin.closeDevice(
    result=>alert(result),
    error=>alert(error)
);

read

example:

cordova.plugins.SerialPortPlugin.read(
  res=> {
        console.log(res);
        alert(res);
  },
  error=> {
      alert(error);
  });

write

example:

cordova.plugins.SerialPortPlugin.write('12345678900000000000000000000000123',
  res=> {
        console.log(res);
        alert(res);

  });

cordova.plugins.SerialPortPlugin.sendDataAndWaitResponse('12345678900000000000000000000000123',1000,
  res=> {
        console.log(res);
        alert(res);
