Networking in a Script

[CraigNZ]

Has anyone written a script to receive and send UDP packets?  The idea here is for one or more external programs to send 'requests' to a script running on PI.  The script would process the script (e.g., running a calibration on an image) and return a result to the requestor.  UDP is much easier to use because you do not have to setup and maintain a TCP session.

If there is no script, is the Network class in SpiderMonkey available in PI?

A possible alternative is use to use some form of file event scripting where the script monitors a folder and when a new file appears in the folder, it is read and processed similar to a UDP message.

Has anyone tried this?

Craig, there is a FileWatcher core PJSR object, see this thread.

Events are async and dir change info is limited, it appears you need to find what changed yourself.

Thanks,
Mike
