Hi,

I'v a GSM shield and Arduino Uno. I am able to get the following message from Serial Monitor using example programme: GSM/Tools/gsmNetworkScan.


---------
GSM networks scanner
looping start
looping end
Modem IMEI: 359231038101091
Scanning available networks. May take some seconds.
> STARHUB Pte Ltd
> MOBILEONE
> SingTel

Current carrier:
Signal Strength:  [0-31]
Scanning available networks. May take some seconds.

Current carrier:
Signal Strength:  [0-31]

Why the signal strength is empty?

Thanks for any help...

Hi,

same here. Did you solve the problem?

Best regards

Hi,

Execute the sketch replacing the line:

GSM gsmAccess;

with:

GSM gsmAccess(true);

Post your serial output.

Replacing GSM gsmAccess; with: GSM gsmAccess(true); doesn't change the serial output. I partially solved the problem commenting this lines:

//  Serial.println("Scanning available networks. May take some seconds.");
//  Serial.println(scannerNetworks.readNetworks());

now "current carrier" and "signal strength" are working.

I don't understand. In my shield in Spain works perfectly. Although, it's possible there may be a bug in the library.
Could you show more details?.
