Ciao
Sto' provando a passare l indirizzo mac via vettore, ma non riesco a capire dove sbaglio
sotto le righe incriminate nel setup e nel loop
Cosa e' che non so'?
broadcastAddress[] = { mac_Add[id_sens][0], mac_Add[id_sens][1], mac_Add[id_sens][2], mac_Add[id_sens][3], mac_Add[id_sens][4], mac_Add[id_sens][5] };
sotto il messaggio di errore

This is an example for our Monochrome OLEDs based on SSD1306 drivers
Pick one up today in the adafruit shop!
------> http://www.adafruit.com/category/63_98
This example is for a 128x64 pixel display using I2C to communicate
3 pins are required to interface (two I2C and one reset).
