Yes, the Pixl is powered with 5v USB. If I measure on the ESP8266 it shows 3.3V.

Flipping tx with rx gives same result (empty string)

I also still just get empty strings as response if I set SW1 and SW2 to 'off'.

Same thing with the first piece of code in #18 from allObjects which returns this;

I did order the USB-TTL converter so I'll give the firmware update instructions a shot when I receive it. I'll update here when I have tried that. Sorry if I missed trying something out but as I'm all new to this it's easy to get lost in all details :)
