I remember seeing somewhere that most of the problems are from the communication speed not matching between the ESP and the STM? Where do I set this in the ESP code? or tools? And to what number?

Hmm So using Grok I was able to add to the code to get it to change channels. But I have tried channel 6 11 and 13 as well as 1 and nothing is working very good. IN fact its all very Unusable. I am not sure what to do. Is there another way to set up the VCU? Can I make a USB connection or use a TTYL ...

Thank you. I will look at this when I get home.

One of the biggest problem I have ever had with wifi on Zom and other OI boards is if there is another accesspoint or wifi source in the vicinity on the same channel. You can test this with a wifi scanner app.


So I think the App is showing me its on channel 1 which is conflicting with a ARLO ...

Hi I have made progress. But as you can see in the video it doesn't seem like a great connection its usable but barely and never works on my phone. Anyone have any ideas on how to improve this?

I am dealing with these issues as well. It seems there is a problem with the stream from the STM to the ESP not staying consistent. I have tried 2 different ESP82 chips so far and 1 is better but neither work good enough for me to trust it.

Ok to make sure I am clear. I have mine working but it has issues. It works for a bit then gives the warning "connection problem between ESP and STM." I guess this is more likely a problem with RX and TX? Seems a LOT of people are having this problem.

I am dealing with issues with mine as well. I have some random ESP8266 and I honestly don't know which one to get. Non the less I feel I am close. I followed the settings in the video above but I see the readme in Arduino says to use different settings.

Try this thread. Its not easy to program the ESP8266 with what you need to do. There is 2 major steps and I am sorting mine out right now as well. I will also post in this thread to keep things easier for others to find in the future. viewtopic.php?t=5725

Then access the web page at 192.168.4.1 which is the default IP address for the ESP32 web server.

Thank you.

Oh how to get the Web page to load from my PC so I can set the settings etc.

In order for this to work do I simply log into the wifi that the board is displaying in the serial output?

I am getting stuck on this part. But I have been off of it for a while. I am ...

Tried it this way as well. Still 0.0.0.0

Also do I need to change WiFi.begin("Beetle_CHademo", "Fia84grapu"), to something else?

Thanks

Ok back to this. I think I found the problem. Is default IP for ESP32 should be 192.168.4.1 But mine is not defining the default serial.
I added this in the INO file.

And got this in the serial printout on the Arduino screen.


Anyone know how to add a set IP address? image.png


And ...

ESP is picky regarding power supply. It usually crashes if the voltage drops due to high current consumption during WiFi transmission. Use a lab power supply or at least a shorter heavy USB cable.


I have tried a 100w USB wall adapter with a short and thick USB cable. I have also done the 3.3 ...

If you connect to the ESP32 wifi network and the ip address will be 192.168.4.1

hello everyone! Can I also ask a stupid question?
Can this device work with a hall effect current sensor? or on a regular 75 mv shunt?
Isabella's shunt is very expensive, it seems to me, in order to be accessible to the masses.


You will want to use a shunt. The problem with the hall effect ...

I did have to put a jumper in.

It doesn't have any analogue inputs, but you could add. You could also change the code to not require any current/voltage monitoring and trust the values the charger is saying, if you so wished.


Oh what is the resistor for?

Edit I ...

When you give the board the 12V supply the ESP32 gets 3.3v from the AMS1117


Thank you. So I run a jumper from the 3.3v regulator to the 3.3v pin on the ESP and it still didn't work.

I then tested a new unused board from the GitHub files and it doesn't have continuity from the 3.3v regulator ...

How is the ESP supposed to get power from the shield?
I see the pin for 5v is not ...

Hmm interesting. I will follow this close. I need to read it again. But will ask one question. Which is to charge it sounds like you plan to have the vehicle on in "Ready" Or do you plan to do it VIA the signal from the AC charger? And do you know if in either case the Rav 4 will get angry when that ...

Thank you.

I tried looking though the code and I didn't see "192.168.4.1"

So I tried this and connected via wifi but it doesn't work to type 192.168.4.1
I tried this on my PC and with my phone. Neither seems to ...

Actually all I think I need is to know how to find the web server or the IP address its not spitting it out how do I get that last step working?

Did you figure out where to tie into the DC pack voltage?

Any chance we can get a read me for the gui setup?

Thanks.
