node.js serialport - TypeError: "offset" is not an integer
node.js serialport - TypeError: "offset" is not an integer
我正在尝试打开串口并读取传入数据:
const SerialPort = require('serialport');
var port = new SerialPort(
"/dev/ttyUSB0",
{ baudRate: 115200 }
);
port.on('data', data => {
console.log(data);
});
port.on('error', err => {
console.log('Error', err);
});
port.on('close', err => {
console.log('Closed', err);
});
每当新数据到达时,上面的示例都会失败并显示 TypeError: "offset" is not an integer
:
Closed { TypeError: "offset" is not an integer

我已经尝试 @serialport/terminal
(source here) 并且它按预期工作,所以很明显我的代码有问题,但据我所知我正确地遵循了文档.
您使用的是哪个版本的串口?确保您没有使用 8.0.0 分支。
