python mqtt loop_start无法发送消息 一、我为什么要在flutter项目中使用mqtt? 我的项目是使用flutter开发,然后有一个功能是我们需要和蓝牙网关进行通信,然后网关通信使用的mqtt协议。由于flutter的pub仓库中提供了非常方便的插件——mqtt_client,所以我们可以使用这个插件,非常简单方便的就可以实现和网关的通信。 二、使用...
loop_start()是启用一个进程保持loop()的重复调用,就不需要定期心跳了,对应的有loop_stop()。 loop_forever()用来保持无穷阻塞调用loop() """ # todo 用于线程结束 BreakThread = [''] def command(client): while True: if BreakThread[0] == 'exit': break elif len(List) >= 1: paramCommand =...
