I use Arduino IDE to upload sketchs.
In some cases when i try to upload the sketch i dont have any response from the board. In fact when i plug to the USB it doesnt blink the blue led that have the ESP board.
I try to cut the CP2102 buildit-in on the LoLin board and i make a board to upload the firmware but it doesnt work in all modules. In the case that works the blue led blink when i plugged.
Any have some idea what is happening?
