ionic3 基于cordova编写的安卓串口通信插件 ionic3 serial port plugins for android

support

1. read string & hexString
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.
6. UART device does not check data is complete & right. you should have a protocol for exchanging data between two devices.

how to use

1. add the plugins to your project 'ionic cordova plugins add ./cordova-plugin-serial-port'
2. 'declare let cordova: any;'before use api. this way not good. can anybody help me?
3. enjoy

API

openDevice

param:

• 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);
  },
  error=> {
      alert(error);
  });

sendDataAndWaitResponse

response data maybe not complete,you can use read api to get the rest.

param:

• arg1: data
• arg2: timoutMs

example:

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

setHex

you can change the hexString | string after openDevice

example:

cordova.plugins.SerialPortPlugin.setHex(true);

cordova-plugin-serial-port's Issues

Ability to set a response time

I propose to add the ability to set a waiting time for a response to a request sendDataAndWaitResponse.

OpenDevice give undefined result

The following code should work but it returns undefined for result. what would be a compatible es5 function since the example is uing es6 arrow functions?
cordova.plugins.SerialPortPlugin.openDevice([{dev:'/dev/ttyS8',baudrate:9600, flags:0, isHex:false}],
(function (result) {
return alert("result");
})(),
(function (error) {
return alert("error");
})()
);

大佬，刚好我这边也是要弄串口对接其他机器来采集数据，可是我对硬件那边 的流程一脸懵逼，可以请教下吗

插件很棒，请教下读取的问题

读取是要通过定时器来一直读取吗还是有长连接？

谢谢。

can't Cut Paper

Hello,
i am able to print width this plugin but i still can't cut paper.

cordova.plugins.SerialPortPlugin.setHex(true);

  cordova.plugins.SerialPortPlugin.write('0x1D',

res=> {
console.log(res);
//alert(res);
},
error=> {
alert(error);
});

  cordova.plugins.SerialPortPlugin.write('0x56',

res=> {
console.log(res);
//alert(res);
},
error=> {
alert(error);
});

Can you help please

这个插件注意要用[email protected] 打包，不然会报错

Problem with connect

Hello.

I have a problem with the connection to the device.

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

My device connect to dev:'/dev/ttyS1'.

When I try connection to dev:'/dev/ttyS0' I get error with message null& It's good.
When I try connection to dev:'/dev/ttyS1' I get nothing. No error message. No success message. It's bad. But at the same time I expect to get success.

What is it CRC?

Hello.

In your example have CRC. What is it? How to look file ./crc/index.ts?

import  { CRC } from './crc';

several devices

I would like to establish communication with several devices at the same time. How to do it.
dev /dev/ttyS0 and /dev/ttyS1 addresses

I propose to add the ability to send a line for writing, not only in HEX, but also regular lines.

Now:

cordova.plugins.SerialPortPlugin.sendDataAndWaitResponse('2768656c6c6f20776f726c6427', ()=>{}, ()=> {});

I suggest add:

cordova.plugins.SerialPortPlugin.sendDataStringAndWaitResponse('hello world', ()=>{}, ()=> {});
