ESP01 Blue led stays on all the time
If the blue led on your ESP01 board is ON all the time, it means that you probably connected on LED to it.
In this case, LED will act as pull down and the ESP will change the boot mode ( which you didn't want to do it)
So ESP01 will need GPIO2 on HIGH level in order to boot.
