Good Day,

I use the following ADL subscribe funtion for my application to receive the incoming SMS (derived from SMS automation example):

```
sms_automaton_Handle_txt = adl_smsSubscribe(SMS_AUTO_Handler, SMS_AUTO_ctrl_Handler, ADL_SMS_MODE_TEXT);

```

In SMS\_AUTO\_handler i use the following code to intercept the incoming SMS:

```
bool SMS_AUTO_Handler(ascii *SmsTel, ascii *SmsTimeOrLength, ascii *SmsText)
{
    TRACE (( 1, "MESSAGE RECEIVED\n"));
    adl_atSendResponse(ADL_AT_RSP, "MESSAGE RECEIVED\n");
    return TRUE;
}

```

Modem was able to receive the incoming message in fact the whole message i composed was displayed on the terminal emulator. But no trace was displayed on the target monitoring tool and the adl\_atSendResponse was not executed. What could be the problem?

Thank you,  
Von

Did you check the return value for error codes?

sms\_automaton\_Handle\_txt is equal to 0 after subscription.
