For my project I'm going to use ESP-01S (black pcb).On the internet it says it cannot code protect.Anyone can remove the SPI flash chip from the board & read the contents.I'm new to this ESP thing not have much knowledge.
There are two chips on this board.One is 8266 chip & the other one is SPI flash.Then whats the point of 8266 main chip if does not hold any data/programming code?
If you must have code protect you will need a different board.
Reading your code is possible but it will need someone to understand assembly language. If the code were to be read back it will NOT look like the code in the IDE but will be a block of numbers that represent the base instructions to the processor.
So while it can be done, it will require someone skilled and motivated.
