R-Net: Releasing code that lets you control chairs remotely

[stephenc1]

After seeing these posts, you guys are missing the point of what my work is and what the Raspberry Pi is doing, running the R-Net protocol itself.

My interface is not a plug and play item and needs to be fitted into / inside the joystick pod ( Made by PGDT ) ...UNLESS the control system has an OMNI then I can supply an interface that is more or less plug and play.

That's the entire point of my solution. It's an R-Net module, a complete standalone computer with custom addons. That alone what made me reverse engineered the R-Net protocol. I wanted a solution that just worked on any chair with R-Net

If you want RC instead. Get a RF module for the PI itself. Modify my code to accept the RC controller, instead of the USB game controller. There you go, no OMNI needed or opening the R-Net hardware.

And you get additional benefits like speed control, seat control, or access to any other R-Net device. Stop beating yourself with additional headaches like soldering and all that

Might I suggest this App that I use.

Joystick with 6 buttons, 3 datafields....

There is also this option available from Kas with video via Wifi.

.

Also, this might work as with minor code changes and additional RF hardware to the PI.

Since there is RC apps already, I will see what needs to be done to support general RC apps so that you can use any RC app you wish.

This is very cool Stephen, but I think the other BIG thing that many of us are hoping for is to figure out the programming so that a user can adjust all the stuff that can be changed using the factory OEM level programming software, without needing the expensive and nearly unobtainable dongle...

Any ideas on how to either 'de-dongle' the factory software, or to replicate it's function without needing the dongle?

My friend and I have been working on this issue as much we can. We only have time after life duties. We have been reverse engineering the actual firmware, which has thousands lines of code. We could use help with the rnet file format.

The first step is to pull apart the rnet file format.

Any volunteers?

Once rnet files are decoded any platform can be used to change settings. I would like a list of people who will be willing to work with a HEX editor and be working on this with us. We want more people to join us.

[stephenc1]

This is what a rnet file looks in a hex editor. As you might be able to see I've been editing my own parameters.

I know it looks complex and scary, but you guys can learn to read this. The rnet file stores blobs of the EEROM that get mapped to the chair's memory.

I'm focusing on making apps work with the R-Net protocol. And my friend is reversing the code that is the R-Net protocol itself.

There are over 200 estimated parameters a person can change within the R-Net settings. Far more than what you may believe.

[stephenc1]

My goals are:

1. Answer: How do u upload an rnet file to a chair without the dongle? I have partly answered that with the PI hardware. But we need more hands on making the program that sends this file.

I have a programmer and I will share the programmer canbus messages that allows programming with a rnet file. The hard part is emulating the order of these messages sent by the programmer. We can use the can2rnet library to do the sending.

People can help here.

Not sure what file you are trying to decode. Above a link to Permobil r-net factory default configuration files.

Perhaps useful to know that the Permobil r-net dealer sw can be downloaded from http://www.permobil.com/fr/France/Assis ... rogrammer/

This helps a lot. The files I'm decoding are *.rnet and *.rnss because that's what the chair's parameters are stored in.

It is less guesswork for us to make a program that uses the same format.

Once the files are decoded, then one can see their speed settings, jsm settings and more. And it gives us a way to store them back in a chair.

This is great Stephen, thank you for your hard work.

I dont have a Pi...or an Rnet chair but i do have the OEM software (not cutting up the cable...).
I also have Leonardo Can Bus Arduino boards , available in the UK.

Once i finish tinkering with the Arduino i am doing the same for the Dynamic Shark, i think i will have a go at this.

Cheers
