Hi, I am using the gsm_modem sample with a nrf5340dk and a LARA R211 gsm evk. I have added 3 AT commands to gsm_ppp.c:

static const struct setup_cmd setup_cmds[] = {

    SETUP_CMD_NOHANDLE("AT+CGATT=0"),

    SETUP_CMD_NOHANDLE("AT+CGREG=1"),

    SETUP_CMD_NOHANDLE("AT+CGATT=1"),

    /* no echo */

    SETUP_CMD_NOHANDLE("ATE0"),

    /* hang up */

    SETUP_CMD_NOHANDLE("ATH"),

    /* extended errors in numeric form */

    SETUP_CMD_NOHANDLE("AT+CMEE=1"),

    /* disable unsolicited network registration codes */

    SETUP_CMD_NOHANDLE("AT+CREG=0"),

    /* create PDP context */

    SETUP_CMD_NOHANDLE("AT+CGDCONT=1,\"IP\",\"" CONFIG_MODEM_GSM_APN "\""),

};

I just wanted to find out, is there any other approach I can take towards adding those 3 AT commands without altering the gsm_ppp.c file. Is there some approach similar to using an overlay file in the applications directory?

Regards

Brenton
