@windalser here is the "fix". It really did not delete the binaries from previous builds so they grew in size.

compiles fine either way Not sure what's up on your end

will have a look. The symptoms lead me to believe that old binaries are not cleaned before the new ones are created. I had it happen on unix, maybe something like the previous one.

uart is exactly the same as on ESP8266. Just offset same code runs on both, but you need to pay attention when setting the pins.

the best thing is to edit the header for the library and add In RTOS there is no need to yield any longer. I was thinking wether I should add this to Arduino.h and make such issues dissapear

I have not looked at UDK's upload script, but you can change the bandwidth and upload faster

Done!

Ha! Funky! Will dig more windows today :D Not a windows guy here for sure :) but python is unhappy. Any other errors there? Because it's the python that created the file it says is missing... could you look in the temp folder after such error and check if there is such file there? Maybe I need to ta...

you mentioned "...\Arduino15\packages\" this is not the folder I am talking about! That folder is for packages installed through the package manager. You need to go into C:\ProgramFiles(x86)\Arduino\ (if that is where you installed the Arduino IDE) and then in the hardware folder inside (starting po...

Paths should look like this: ....[Arduino]/hardware /avr /tools /Espressif << create that one and clone the repository inside /ESP31B << this is the git repository /core /variants /libraries /tools << extract the toolchain inside this folder /esptool.py /gen_appgin.py /sdk /xtensa-esp108-elf << this...
