插件介绍

安卓串口操作原生插件，支持设置串口，波特率，停止位，数据位，校验位，流控以及延迟，支持粘包处理解决分包问题，支持多串口操作，无需root

用法

在需要使用插件的页面加载以下代码

const module = uni.requireNativePlugin("leven-serial-SerialModule");

多串口操作

如果您的项目涉及到多串口的话，可以多引入一些module，目前插件提供了以下几个module

const module = uni.requireNativePlugin("leven-serial-SerialModule");
const module2 = uni.requireNativePlugin("leven-serial-SerialTwoModule");
const module3 = uni.requireNativePlugin("leven-serial-SerialThreeModule");
const module4 = uni.requireNativePlugin("leven-serial-SerialFourModule");
const module5 = uni.requireNativePlugin("leven-serial-SerialFiveModule");

如果您不想这样使用，多串口可以直接使用const module = uni.requireNativePlugin("leven-serial-SerialModule");然后在使用时打开不用时关闭即可（即按需使用）
如果多串口一直保持打开状态的话就需要引入上面的module
