Cctalk message timeout

💥 Proposal of cctalk parser

What feature you'd like to see

The time between accepted bytes in single cctalk packet cannot exceed 50ms. I want the internal buffer CCTalkParser.array to be reset if I get bytes after delay of more then 50ms.

Motivation

I have cctalk devices in my project. CCTalkParser is used to fetch data packets from serial device. It fetches packet LENGTH out of the header bytes, waits until LENGTH bytes is received, and gives back the whole packet.

And sometimes I get corrupted data on my data line. That is ok, I can check if the packet is correct using packet checksum. If the checksum is invalid, I ignore the packet.

The problems begin when I get corrupted LENGTH byte. The borders of different packets are mixed. And there is no way to fix it, I have to reopen the serial device connection to restore communication with my cctalk devices.

Pitch

I want it to be implemented directly as it is written in CCTalk protocol specification section 11.1.

I’m for it, let’s make this breaking change. Better to be on spec 🙌

If you can, update the docs in the website repo too! And I’ll cut a beta version of the package so you can try it out.
