Firmware of V2 hardware #241

I've bought a second hand version of the OTGW V2 from Nodo-shop. It seems to work but I get the error "Error: OTGW: Error received!: " in my Domoticz. Now I first want to start by updating the firmware but I'm unsure how. My current mainscreen is as follow. ScreenHunter_45 Feb 11 14 22

  1. Is it correct that the right firmware for this is located here ?
  2. In the "Tools" "Firmware Update" there is only one "select file" button, while in the instructions there are 2 buttons. Is this because the current version is old or am I completely wrong here?
  3. How can I debug this to find the reason it is giving the errors?

Follow the instructions on the wiki how to install: https://github.com/rvdbreemen/OTGW-firmware/wiki/How-to-install-firmware-on-your-ESP

I noticed in the screengrab you installed EasyESP. Do not try to update using that. I have not tested an upgrade using EasyESP.

The lastest release is currently #24 you found on the GitHub.

Hope you can flash your OTGW with ESP.
