SMS

Sending SMS

to use SMS function it is not required to initialize it. Just use write_buf(); functions and read_buf(); functions as is Done in example part 1:

example part 1

main()
{
    write_buf(SMS, 17, "+3706xxxxxxx", "Device started...");            // Send SMS
    while (1)
    {
        fuel_level = get_val(Sensor_FuelLevel1);                        // Read fuel level
        if(fuel_level<low_fuel_level && Send_Fuel_report == 1)          // If fuel level is lower than limit and SMS report is activated
        {                                                             
            write_buf(SMStext, 17,"+3706xxxxxxx", "Fuel level is low"); // Send indication message
            Delay(3000);
        }
        Delay(1000);                                                    // Check every 1 second
    }
}

Reading SMS using callback

to read any received SMS it is needed to use callback. Use read_buf(); to get information from SMS as is done in example part 2:

example part 2

public callback (sk)
{
    switch(sk)
    {
        case SMS:                                             // If SMS callback event
        {
            read_buf(SMStext, 99, sms_text);                  // Copy SMS to string
            read_buf(PhoneNumber, 14, number);                // Read phone number to string
            if(strequal("+3706xxxxxxx",number,true,12) == 1)
            {                                                 // Check number
                if(strequal(sms_text,"OFF",false,3))          // Check message content	
                { 			
                    Send_Fuel_report = 0;                     // To turn off reports
                }
                else if(strequal(sms_text,"ON",false,2))      // Check message content
                {
                    Send_Fuel_report = 1;                     // To turn on reports
                }
                low_fuel_level = strval(sms_text,3);          // Changes low fuel level
            }
        }
    }
    return 0;
}
