7.3.1 Integration to the application
Integrate in your project the modem driver library (see chapter 5 to 5.3). But when
doing the configuration of the DB_Modem you need to consider, which are the values
for the parameters to use in conjunction to the Page Center. It means, what is the
phone number of the Page Center (with necessary prefix), which is the baud rate
supported by the Page Center.
1. Integrate in your project the Pager function FC600,DB600 and UDT600.
2. Configure the Pager_DB (see 7.2.2 and 7.2.3).
3. In Data Blocks, prepare the message in a string format and not longer than 140
characters (maximum is usually less, depends on the provider).
4. Call the function FC600 in a such way that:
• Make the request to send a message, when the connection has been
established, for this use the signal CONNECT from the modem Driver.
• Cancel the Calling request when the SMS function return an signal
DONE or ERROR .
