As Barry said, there's no way to open up listening sockets on App Engine.

But some microcontrollers have enough space to host a tiny web server (see
this SO post for
examples<http://electronics.stackexchange.com/questions/72566/why-do-people-create-web-server-on-a-microcontroller>);
what you can do is run a web server on your device, then have App Engine
periodically poll the server for data.
