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:

Rebooting...
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

Any advice would be greatly appreciated.
Thanks
