I can't get the genuine "Arduino GSM" Shield to work on a UNO R2.
Powerered by external 12 Volts 1000 mA and connected to my PC by USB.
I tried the Tools:
-"Test Modem" = Fine.
-"Band Management" = Yes.
4 : E-GSM(900)+DCS(1800) ex: Europe (Switzerland)
Configuring band EGSM_DCS_MODE
-"GSM Scan Networks" = Yes !
Scanning available networks. May take some seconds.
Current carrier: Orange
Signal Strength: 19 [0-31]
So I tried: "Receive Voice Call",
but I commented out //vcs.answerCall();
because I just need the calling number. (If you're on the Guestlist, a Relais will powers the Dooropener)
But nothing happens, it just print out "IDLE", no Number.
What can I do to figure out what is gooing wrong ?
