Hello i tried the Examples in the Arduino Lib. But i cant connect.
Has Anybody some Knowhow with this Board?
How is the best Start?
2 Antennas testet, both nothing.
My SIM is German Carrier Congstar (Mobilephone with Data, no Onlydatacard), but in the Cellphone the Card works fine without PIN...
While im on testing o got the follwing results...
Example "Bandmanagement":
Current band:EGSM_DCS_MODE
...not changed since i buy the Arduino
Example "PINmanagement":
PIN/PUK locked...try it in a cellphone
-> this i did then, ... and it works without problems and i have data "H"
"TestModem"
...Modem is functoning properly
"GSMscanNetworks"
GSM networks scanner
...thats all, it hangs at this
MODEM.debug();
some OKs...
some Errors...
AT+CPIN?
ERROR
try delay reponse after set band
GSMBand band;
band.begin();
String bandName = band.getBand(); // Get and print band name
Serial.print("Current band:");
Serial.println(bandName);
delay(100);
band.setBand(GSM_MODE_GSM850_PCS);
delay(100);
bandName = band.getBand(); // Get and print band name
Serial.print("Current band:");
delay(100);
Serial.println(bandName);
I have the same issue. I use 2 sim cards, a main and a second card. The second card works fine and in debug mode I get the AT+CREG 0,1. The main card stays on CREG 0,0.
For anyone, looking for info on this, check the band used by your carrier through this site GSM World Coverage Map- GSM Country List by frequency bands and change your band to the correct one using Band Management, I had to use the last option even though the E-GSM & DCS should work but the carrier was autoconnecting me to 3G which used 2100MHz.
