Yes, compiled myself in both cases.

Investigating some more, i see a small difference on the hardware side that might be affecting the issue. The D1 mini V1 got a 470Ohm resistor on both the RX...

Take a look here, i think it lists the Wemos mini models with their schematics, might come useful. https://wiki.wemos.cc/products:d1:d1_mini

Just uploaded the precompiled bin over OTA, same issue remains. I don't have a 470Ohm resistor...... need to find one.

Ordered the resistors but also got an idea, is it possible to define different pins for RX and TX, essentially redirecting them to different GPIO pins? If yes then do...

I got the resistors, will have to solder them in tomorrow and will let you know, there is always the possibility that i got a defective module, but while searching...

So, i soldered the resistors (470Ohm) on both TX and RX, still doesn't work. I am out of ideas, its either a defective board or Wemos D1 mini V3 has...

So i am back with more info. Till now my theory was that since TX and RX pins of any ESP8266 are 3.3v tolerant (they might work with 5v logic...

Build myself.

and each time i build i make sure to erase whole flash with Wife settings inculded.
