Hi, no that will not work. You need to change the function by adding the two lines below:

Code: Select all//********************* CHANGE PIN FUNCTION **********************
pinMode(led3, FUNCTION_3); //GPIO 1 swap the pin to a GPIO.
pinMode(led4, FUNCTION_3); //GPIO 3 swap the pin to a GPIO.
//***************************************************************************
pinMode(led1, OUTPUT);
pinMode(led2, OUTPUT);
pinMode(led3, OUTPUT);
pinMode(led4, OUTPUT);


Thank you very much, but does this affect the module when reflashing it? as the tx is no longer tx, it is gpio?

No it doesn't. When it is in boot loader mode (re-flashing) it is not running your code.

Thank you very much....
It worked fine to me.
