Joy Module about can2rnet HOT 1 OPEN

Yes, the way is to use wireshark, but until there's a R-Net Wireshark plugin that implements the full R-Net protocol, you only get the raw data in canbus frames. If somebody can create one, then great! My research can be a starting point for this.

As for the Joy module, the error inducing is a quirk/hack that I used as my advantage. You see, the joy module still sends movement frames regardless if its touched, the frames are 0, 0. X and Y positions. The chair responds if it gets a move frame within 10ms or something like that, it gets confused otherwise and tries to do it all if we send move frames from a program. So the easy way to fix this was silencing the joy module. The added benefit is that the chair stays on. People think it's plug and play, but R-Net has its own thing and handshakes when registering a r-net device like joy modules. You have to do this in software, and since r-net isn't fully reverse engineered to begin with, we can't emulate a proper joy module. If you can do this, feel free to add the library.

I'm not familiar with at all with the invacare power wheelchair with Linx electronics, I have no idea if it uses r-net or not, my guess is no. But my research can be used to guide you. Chairs with R-Net do not rely on joy modules for charging/battery states, it is a passthru system. So, sorry. I don't have an answer other than fully figuring out the R-Net protocol and permobil's secondary seating protocol.
