**********************************************************************************
* 
*  The first boot after downloading programm take above 5s.
*  Next boot takes under 0.3s.
*
*  So when we are at first boot, we can force programmatly a hard reset.
*
*
*  To do this :
*
*
*   choose your forceResetPin ( but dont use a reserved pin ;) ). 

*   HARDWARE 
*
*     connect the 'forceResetPin' to RST pin. 
*
*
*
*   SOFTWARE
*
*     (*) define the 'forceResetPin' (for ex : 	#define forceResetPin D7).
*
*
*     at the begining of setup() (RESPECT THE SEQUENCE TO AVOID AN IMMEDIATE RESET)
*     (**)  -  set the 'forceResetPin' to HIGH, 
*		  (***) -  configure the 'forceResetPin' to output mode.
*
*  Then, a little further :
*     (****)if this is the first boot, force reset by pulling down the 'forceResetPin' to LOW.
