Interesting. I just got my CAN Shield and I was testing it on my Jeep. I couldn't seem to get any results. I was avoiding using my wife’s Toyota so I didn't screw it up but decided to give it a try and got a flood of frames in the output. This video seems to have answered the why. Thanks for the video!!! Your videos are a great source of information!

You are so awesome man. I really appreciate it.

[@KarlKristianMoeng]

Very good video!

[@juliotroche3835]

awesome information. I'm definitely getting that esp32. 1 question does that can information come from the ecu? in my case I would like to connect it to my motorcycle.

I have seen your webserial vid. Have you thought about a universal project to connect a existing nano (or any arduino) project that will connect to its serial port and a esp8266 or esp32 reads nano serial port and retransmits it via webserial. It can be used to temporarily troubleshoot/instrument a simple project that does not need full time webserial.

@MrDIY thanks for your tutorials!
Do you see any chance to control a car using CAN bus / OBD II so it could drive itself?
Let's say, go into drive mode, release the brakes and go forward very slow and then brake and stop again...

You might want to check a project called OpenPilot

@@MrDIYca thx so much. Will have a look.

[@fredimachadonet]

It would be awesome if you could create a tutorial on how to use your board and ESP32 to open a garage with a button on a Tesla steering wheel. Thanks for your content!

[@MrDIYca]

yes, that is coming up next :)

[@CubbyTech]

A vehicle manual won't show how to connect to the CAN bus. OBDII is not a protocol, and the CAN bus lives on the OBDII port.

[@langtupt]

maybe controller to KIA Car?

[@MrJimmyPenguin]

I sent you an email, on a project I'm attempting with your OBD boards, any insight would be a life saver.
