This is a typical example - I have isolated 2 Lamps that I can switch On and Off. I have saved the logs and wouuld like to convert them to a DBC file. Do I need to do it manually for each CAN message?
Oops, can't attach as it is in .fsd . I will try to convertit tomorrow.

Yes I've had a look at those thanks. This is all practice before getting into the VW charger integration on my project. What I am trying to get to understand is how to go from recorded data from a working vehicle (or bench setup) to creating a dbc file that's readable. Afterthat, I am looking for li...

Still waiting on that CanCrocodile. In the meantime.....I managed to capture some data and also identify the ID's that switch on lights and command the Rev counter. This is a huge step for me into understanding CAN and the bits and Bytes. So now what? I'm looking at DBC links from previous posts, bu...

I can confirm transmitting works on Bus 3 !!!! Huge thanks @uhi22 !!!
I started with some Fuzzing and found my ID for RPM - 0x280. I'll play around now to see how to select and hone in on bit values.
Baby steps

I found some info on can id that I'll try to configure and send to my bench setup to instrument cluster. Will confirm if it works. Trying to see if I can use my vcds to extract can related data at the same time.

Whilst waiting on my 'CanCrocodile', I found some info on CAN Id's. https://hackaday.io/project/6288-can-bus-gaming-simulator/log/19473-rpm-can-address-found Could I not use this data in SavvyCan and send it to the instrument cluster I have on my bench? I just want the rpm needle to move a few times...

@Jacobsmess ,Sorry to hear about your BMS blow up. I am following and not far behind you in the whole Can ID and reverse engineering parts of my build. Thanks for asking the right questions and thanks to all contributing. I have a crocodile clip CAN reader on the way to hopefully speed things up. I ...

Crocodile can analyser connector on the way then....

That explains why I can't find examples. I'm trying to do some trial and error setups. So, any components we want to reverse engineer require working CAN logs?

I finally have my SavvyCan setup working (Thanks to @uhi22 and his wifican). I also have a VCDS running in parallel to a Mk5 Instrument Cluster. I have been playing back Test Sequences for the Speedometer and Rev Counter. I have logged some files and played them back, but none of the playback messag...

Happy can fuzzing and dbc searching

Bienvenue!!!! I live in France too and hope to "bump" into you and your team sometime! Bravo.

Please check that I have correctly documented your great solution in the Wiki

I have 2 wifi names, I removed the _5GHZ from the file, and it has connected to the 2.4GHZ network. I can also connect it via SavvyCan!!!!
Huge thanks, and time for me to do some Wiki writing. Thanks again @Uhi222 !

Thanks again, but after several attempts , I get a "STA STARTED" and then repeatedly "STA DISCONNECTED" when Resetting my ESP32. I've errased and refreshed the sketch a few times now. I even reset my Wifi and WPS button. I wonder if I have some kind of setting blocking the connec...

It looks like the correct details are in the credentials file, but Savvycan doesn't find it, or connect when I manually put in ip address. I'll change the baud rate in arduino and see what info I can retrieve to compare what you posted. Thanks for the replies, this is a great tool I think . Can't wa...

That would be to check messages in 'serial monitor' right? I'll try to check pathway for wifi_credential.h to make sure it's taking the correct password etc. There's no firewall settings or something that could block this type of connection? When I browse wifi networks around me,connected or not, th...

I'm back at home. I must be missing something. I can get SavvyCan to connect only when in "field mode". It means I can't have internet at the same time. In Serial Monitor, there are simple "blank squares" and then "x" between them. If I press the "reset button"...

That's what I did. No wifican. Wanted to get this all sorted out to add to the wiki.
I'm away a few days so remote mode will have to until the weekend.

For info, I only can get it working with Pin35 to GND. Tried Pin35 to Pin 47, Tried Pin35 to 3.3v. So for now, only remote access is possible. Wifican is not detectable when Pin 35 pulled HIGH.. My wifi network and password have to be Inside of the "wifi_SSID" and "wifi_password"...

Ok, thanks for that. I'll do that. It's perfect as I'm trying to find reliable dbc files....

Once I've got mine up and running and that I understand, I'll do a wiki update. I'll try the debug setup first that seems to loop. Then get some info from a can bus. I have an instrument cluster I'm playing with, but I think it needs a wake up message first, so will try to connect to working bus fir...

I assume it's normal to have some kind of data loop going through 2 ID when you start up Savvycan without any Canbus connected?

@Jacobmess, thankyou for this info!! This was my problem. The Wifican password is "topsecret" and not my home network password. So once the "credentials.h file has been modified with local your wifi details", load the sketch and connect to the new "wifican network" usin...

Thanks, I'll look at it in the morning. Appreciate all the help, but feel really useless at the moment.....
