以编程方式将Android应用程序连接到ESP8266

Question

我们正在尝试将我们的ESP8266连接到安卓版本6+的设备上的Android应用程序，该应用程序是以编程方式连接到esp8266访问点，使用http请求发送和接收一些命令，该应用程序与android工作正常版本低于6，某些使用Android 6及以上版本的手机上的应用程序工作正常，其他手机根本不工作（也就是说没有连接到esp）。该应用程序正确配置网络，但手机不能正常运行。以编程方式连接到它但是如果你在设置中从wifi中选择它而没有要求密钥（这意味着网络配置正确），它会连接到它。 编辑：当您删除其他可用的已配置网络时，通常无法工作的电话可以正常工作，从而只留下ESP配置的网络连接到
