Ethernet gateway not working after upgrade

Neil_Nutt · 2023-06-15T00:05:30.077Z

Hi
I’ve been ignoring this issue for quite some time and just getting by with a constant 32amp charger. I upgraded the wifi gateway firmware (esp32-gateway) via the web interface on my OpenEVSE a few months ago and I’ve not been able to connect to it since (wifi or ethernet). I bought my OpenEVSE in October 2022. Here is what my invoice says if it helps you understand what hardware I have.

It was working okay with the firmware it came with before I updated it.

When I finally got round to viewing the serial output today I am getting the following message:

Mainly double dutch to me. My guess from “Pin 1 is not ADC” is that I uploaded the wrong firmware.

I have had a go at manually uploading v4.2.2 firmware to the board (via the USB port). Hopefully getting the right firmware this time. I’ve tried various connection speeds, firmwares and cables but I still get the same output.

trying to connect

setting serial port timeouts to 1 ms
setting serial port timeouts to 1000 ms

espcomm_send_command: sending command payload

warning: espcomm_sync failed

Any advice would be greatly appreciated.

Thanks

Oh dear, very sorry to hear you’re having issues. Which firmware file did you use for the update?

Assuming you have OpenEVSE WiFi V1 module, the correct firmware is: Success

Can you verify your hardware:

Please share a photo.

Mmm non of the WiFi modules have a USB port, are you sure you’ve got a WiFi module and not an Ethernet Gateway?

Neil_Nutt · 2023-06-15T14:52:21.515Z

Ah right. Yes, I have a wifi gateway. I am at work just now so can’t send a picture of kit, but it is one of these. I’ll look carefully when I get back to see which variant it is.

ESP32_WiFi_V4.x/docs/wired-ethernet.md at master · OpenEVSE/ESP32_WiFi_V4.x · GitHub

Looking back at what I uploaded, it was “openevse_esp32_gateway-e.bin”. I am guessing I probably have an “f” or “g” variant. Pretty sure I was trying those last night…will let you know how I get on.

Neil_Nutt · 2023-06-15T22:45:40.416Z

Got it sorted. Firstly, I installed the wrong firmware. I installed openevse_esp32_gateway-e.bin rather than openevse_esp32_gateway-f.bin

Then when I was trying to upload the correct firmware I was getting a random error as I wasn’t following the instructions at ESP32_WiFi_V4.x/docs/wired-ethernet.md at 4.1.2 · OpenEVSE/ESP32_WiFi_V4.x · GitHub. More specifically, I was being lazy and using “esptool-gui.exe” that I thought had the same functionality as esptool.py, but it doesn’t.

Thanks for pointing me in the right direction

Nice work!
