2.3.2.3. AT commands for making “Data Connections”
[Configuration for data connection parameters]
AT+CCGDCONT=1,”IP”,<APN>// configure parameters (PDP Context)
E.g.1, if your operator’s APN setting is “internet”
“AT+CGDCONT=1,"IP","internet”
E.g.2, if your operator’s APN setting is “wap.vodafone.de”
“AT+CGDCONT=1,"IP","wap.vodafone.de”
2.3.2.4. AT commands for deregistering from mobile network
[De-register]
AT+CFUN=4 // Radio off, entering flight mode
// After de-register, if you need to register to network, using AT+COPS=0.
[Power Off]
AT+CPWROFF // to turn Modem power off.
2.3.2.5. AT commands for switching Band
If you want to switch band, you need to do the following AT commands by sequence.
AT+CFUN =4 // You need to radio off before set band.
AT+XRAT=1,2 // Set band to Dual band, 3G preferred
AT+XBANDSEL=850, 900, 1800, 1900 //Optional, only if you need to select the frequency
AT+COPS=0 // to camp to mobile network via the band you set above.
2.3.2.6. A classic example of AT commands for sequence
1. Make sure no SIM password is required. You can use another mobile phone to disable the SIM
password. Or, you can use AT+CPIN=”<your PIN>”
2. To enable Modem and camp to GSM/UMTS:
i. Send “AT+CFUN=1”, to enable Modem.
ii. After receive “OK”, send “AT+COPS=0 “ to camp to GSM/UMTS network.
iii. You can use “AT+COPS?” to check if it succeeded in camping to GSM/UMTS
z Success case will be the response like:
+COPS: 0,2,"46692",2 or
+COPS: 0,2," ChungHua Telecom ",2
z Fail case will be the response like:
+COPS: 2
iv. After camping to network, you can always use “AT+CSQ” to check the signal strength.
3. For data network connection,
i. First, you need to configure parameters (PDP Context) by using:
“AT+CGDCONT=1,"IP","internet"”
ii. Now you can use “MS-Windows Dial-Up Network” or the other dial-up tool (e.g., Wvdial) to
make a ppp connection by dialing “ATD*99***1#”
(The generic AT command are as in 3GPP 27.007 specification [1]).
