Data over Homeplug

[orhunsuzer]

Hello dear users,

I have a little question regarding the homeplug communication.
For an experimental work, I need to send data via Homeplug. In every example or documentation, always the etherenet data is sent over the Homeplug however I want to send a data which is not in the form of internet data packages. It can be a serial data between two microcontrollers or anything else.

Do you know whethet this is possible? Is it possible to send unformatted data via the Homeplug? Or must I somehow put my data into a specific format?

In my experience, that is not easily possible. Every HomePlug device I saw handled only TCP/IP on input. That means that your microcontroller would need to be TCP/IP-capable too.

Alternative would be to break the case and try to directly inject serial data. However, this would be very plug-specific, assuming it can even be done in any acceptable amount of time.

For similar purposes I have used serial to IP converters. That way you can use serial output of microcontroller and IP converter will take case to convert it to UDP (usually)packets. But they don't come cheap...

As said above, yes, serial to IP servers are commonly used. A PC can have a driver called a virtual COM port that creates COMn via an IP link to an adapter.

I use serial to IP adapters in my home and at work.
Care is needed in picking ones that work properly and don't cost much.
