1.2 Initialisation-Steps:
The AL7024S can store a set of parameters (please see also command “AT&W” in the
“AT command manual”). The RS232 interface parameters can also be stored. Our
Socket Modems AL7024S are preset to “AT+IPR=115200” baud rate”. You should think
about the initialisation-steps that should be made every time the AL7024S is powered-
up. For details see also chapter 5.2 in the “Developer’s Guide”.
• Power-up the AL7024S Socket-Modem
• Pull-down the Reset-pin for at least 800ms.
• Eventually adjust RS232-parameters.
• Send “AT” to modem and wait for response.
• If SIM-Pin is required, enter it with AT+CPIN=”xxxx”
• Configure the modem to your required application:
Examples:
AT+CMEE, AT+CR, AT+CRC, ATV, AT+CREG, AT+CGREG.
(AT+CREG indicates Network-status).
Set default-storage for phone book and SMS.
For using Microphone- and Speaker-pins, you should set:
AT+MAPATH=1,2 / AT+MAPATH=2,2,1
• For data connections the following commands / parameters are always needed:
AT+CBST for protocol-selection
AT+MIPCALL for TCP/IP
AT+MIPOPEN for TCP/IP
