 | 
 | Commands, even if it is not connected to a network. If it is not reacting, try | 
 | |
| 
 | 
 | 
 | 
 | also 9600 baud. After getting responses from modem, set it to autobaud with | 
 | 
| 
 | 
 | 
 | 
 | ‘AT+IPR=0’ and store the setting with ‘AT&W’. | 
 | 
| 
 | 
 | 
 | 
 | 
 | 
 | 
| 
 | 
 | 
 | 
 | If no  | 
 | 
| 
 | 
 | 
 | 
 | network some seconds after  | 
 | 
| 
 | 
 | 
 | 
 | can test if the Module requires PIN. Response ‘SIM PIN’ for yes, ‘READY’ | 
 | 
| 
 | 4 | 
 | 
 | for no.) | 
 | 
| 
 | 
 | 
 | 
 | If a PIN is used, enter it with 'AT+CPIN=”....”. The module answers with ‘OK’ | 
 | 
| 
 | 
 | 
 | 
 | and connects to network. It uses the providers in the  | 
 | 
| 
 | 
 | 
 | 
 | list’ (see AT commands interface guide). | 
 | 
| 
 | 5 | 
 | 
 | Check the connection status of the modem. It can be seen by the flashing | 
 | 
| 
 | 
 | 
 | LED (Pin 29 of Socket) and the response "+CREG: 1,1" (After issuing the | 
 | |
| 
 | 
 | 
 | 
 | command 'AT+CREG=2'). | 
 | 
| 
 |

 | 
 | The  | 
 | 
| 
 | 
 | 
 | least 10 to 15 is needed for safe operation. | 
 | |
| 
 | 
 | 
 | 
 | 
 | |
| 
 | 
 | 
 | 
 | 
 | 
 | 
| 
 | 
 | 
 | 
 | Configure the module for your needs (baud rate, information commands etc., | 
 | 
| 
 | 7 | 
 | 
 | see below) | 
 | 
| 
 | 
 | 
 | Set  | 
 | |
| 
 | 
 | 
 | 
 | 
 | |
| 
 | 
 | 
 | 
 | other side of communication to the same. Set ‘ATS0=2’ at the other side. | 
 | 
| 
 | 8 | 
 | 
 | Call the other side by 'ATD..........'. | 
 | 
| 
 | 
 | 
 | 
 | 
 | 
 | 
| 
 | 9 | 
 | 
 | If the other side calls you, set 'ATS0=2' before, so the module will answer | 
 | 
| 
 | 
 | 
 | after 2 rings. | 
 | |
| 
 | 
 |

 | 
 | For a  | 
 |

 | 10 | 
 | 
 | ‘ATD…. ;’ (Semicolon for voice mode). A headset can be connected to the | 
 | 
| 
 | 
 | 
 | 
 | module to speak to the other side. | 
 | 
| 
 | 
 | 
 | 
 | 
 | 
 | 
| 
 | 11 | 
 | 
 | Send an SMS to a portable. See following example: | 
 | 
| 
 | 
 | 
 | AT+CMGS=”0764359988” <CR> Call me today  | 
 | |
| 
 | 
 | 
 | 
 | 
 | |
| 
 | 
 | 
 | 
 | 
 | 
 | 
| 
 | 12 | 
 | 
 | Send DTMF tones to a phone. ‘AT+VTS=1’ sends digit ‘1’. Only one digit can | 
 | 
| 
 | 
 | 
 | be transmitted with this command, so you have to repeat it to send longer | 
 | |
| 
 | 
 | 
 | 
 | numbers. |
