Web interface problems V2.1 mainboard

[PoloLbricolo]

Hi,
I had the same issue, i couldn't upload the arduino sketch to the ESP but i finally achieve the succesfull upload.
Check your RX/TX wires it might help if they are corrrectly connected.
In arduino IDE, under tools, erase flash try seecting all flash contents.
This worked for me.
Hope it helps

Quick update ! The firmware was being flashed to the 8266 all the time , but because I couldn't alter the ssid or create a password ,or
load spiffs I didn't think the firmware had flashed properly - if that makes sense. Anyway ,loaded spiffs using curl - seems you have to use the full path to the files - and then I was able to see the web pages !!! Now all i need is some advice on how to flash a ssid and password in the firmware code - Johannes ' instructions don't seem to work .

I would like to report a problem with WiFi adapter ESP8266.
I tried to upload Rev 4.53R software over Wifi and failed. I tried multiple times and allways when i innitiated the file Olimex would drop into reset and WiFi adapter would fall out. In the end i pulled Olimex out and manually updated software.
Any solution to WiFi firmware update?

A Bug fixed, reflash sketch and spiffs. https://github.com/dimecho/Huebner-Inve ... SP8266.zip

Hi

Again i would like to report a problem.
I took a brand new ESP8266.
I uploaded Johannes ESP8266 web interface ino file.
Then i installed the SPIFs.
Then i got inside web interface and set wifi password and SSID.

Next i connected to my off car V2 board, but web interface wouldnt load parameters! I tried changing the tx/rx wires, but both setups show exactly the same view. Waiting circle rolling at parameter line...
Any ideas?

I loaded flash onto Olimex ESP8266 mod as well as on Wemos D1 mini. The latter is much easier to program. But still i cant connect to the board effectively.

tnx

Hi. I uploaded Dima files to wemos d1, I can see the parameters and can change them, but when I go to the tab where I can enable graphs and click on start, the graph is not drawn.

What could be the problem?

[SciroccoEV]

Do you need the 'auto' box (next to the refresh button) ticked?

[yaroslav]

I want the oscilloscope to work, which works if you establish a connection via uart

You must tick the L or R box next to the spot value you want to "scoope"

[yaroslav]

I use the Dima interface, there is no such choice

Did you ever figure this one out? I have the same problem. It seems I can successfully upload *.bin files to the stm32, but no parameters. I'm beginning to think this is another case of missing files in the "data" folder.

Hi

Well try resetting the STM32 board (manually by a reset button) after you are connected to wifi module. Then refresh interface in your browser.
It seems some packets get stuck before bootloader on STM32 can get them sorted. Strangely i dont have this problem in my car. This only happens on desk...

[Thatguyoverthere]

Yeah I might have another problem (dead stm32 I guess, not getting warm and no ALIVE_LED), so I'll try that after I repair the board.

Arber, do You remember my situation with stm32 after failed uploading bin file?
Thatguyoverthere - first try to connect with STM-32 Link utility to chip - if is possible to connect - he lives, but maybe something is corrupted.
In my situation faster was to replace stm32 chip (was unable to establish connection to chip). I wish You bigger luck than I had
