图传

# 这个例子展示了如何在AccessPoint模式下进行MJPEG流式传输。

# Android上的Chrome，Firefox和MJpegViewer App已经过测试。

# 连接到OPENMV_AP并使用此URL：http://192.168.1.1:8080查看流。

PORT = 8080         # Arbitrary non-privileged port



# Reset sensor

sensor.reset()

你是想使用WIFI模块同时上传图像和数据吗？
我也是这样的问题，但是好像没办法实现

[kidswong999]

很难实现两个进程同时运行。

[17758962566]

@4cbg对，我想使用WIFI模块返回图像，并且能给电脑返回识别物体的数据。你知道解决办法吗？

[17758962566]

@kidswong999 难实现，那可以实现吗？

[kidswong999]

我实现不了。
