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 ...

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.

OK I solved that and uploaded it to the ESP32 Board.

The last problem was I had "include <AsyncElegantOTA> in the ino file as well and had to remove it.

Hmm Thanks for the Help Bigpie

I am still stuggling. I have a couple questions. One is the AsyncElegrantOTA is old and I keep seeing this warning.
"#warning AsyncElegantOTA.loop(); is deprecated, please remove it from loop() if defined. This function will be removed in a future release."
The next ...

Ok So I tried just changing the include file to "ElegantOTA" and got this warning.

Hmm I am having problems compiling the code. I have solved many of the libraries I needed to add. But this one has me stumped.
Also on git hub it says AsyncElegantOTA is archived and is read only it says please consider migrating to ElegantOTA instead.

How hard is that so I just change the ...

Hmm So I got most of the things to work on this. But the first problem I run into is my ESP 32 is too narrow. by about 4-5mm Anyone else run into this problem?

Edit. Now that I have the boards. I was able to see the older ESP32 uses a wider footprint. But you also need to make sure the pinout ...

This forum is turning to shit with people needing to be spoon fed everything that is answered already in the topics.

Yeah in his defence I didn't see the SCH the first few times clicking the link either. But for some reason someone else linked the same link and it showed the SCH. I think I had ...

Hi Guys, I just used these files to place an order from JLCPCB I have most of what I need. I plan to add this to a Rav 4 EV and my next Diy build after that. Does anyone know if we can use the BMS info to work with this as well? I will have a few questions as I go though this.

Hi Everyone,

I am in Nanaimo BC.

I have a 2014 Rav4 EV I am trying to repair with a Tesla LDU.

I had a bad time changing out the one bearing in the gear reduction and messed up the OEM control board. I was told someone here might have their OEM board and or other parts from a conversion.

I am ...

Nice to see you here Arlin.

I must chime in to agree with your experience. I would even go further than 2us dead time.
I use Volt inverter with MBB600 IGBT modules https://openinverter.org/forum/viewtopic.php?p=9791#p9791
While i could set deadtime for 2.6us according to this calculus here ...
