How can i extract the code from a ESP8285 module with Arduino 1.8.10

Hi Guys!
I'm working on a project of a communication HUB for my blinds at home. I bought the Sonoff RF bridge 433 and i can't hook up my remote with it so i want to go see inside of the code what is going on and perhaps change the code to make it fit to my needs. Right now i plug my usbUART to it with the RX-TX and Tx-RX but when i go on the Arduino 1.8.10 I'm not able the retreive the code. The error code is:

collect2.exe: error: ld returned 1 exit status

exit status 1
Error of compilation for the Generic ESP9295 Module card

Can someone help me here? Thanks!

Hi,
Welcome to the forum.

It is not possible to retrieve code back from the controller, especially with the Arduino IDE.
