GSM Shield .Test

Dopo aver inserito la shield premere il pulsante Power Key.
Oltre al led pover si accende il led rosso Status led ed il led verde Net light.
Il led Net Ligh lampeggia a frequenza elevata quando ricerca la rete a frequenza bassa (un lampeggìo ogni 3 sec.) quando è agganciato alla rete.

Nel file GSM.cpp assicurarsi che :
#define _GSM_TXPIN_ 7
#define _GSM_RXPIN_ 8
