Initialization2.5. Setting time and dateThis function updates the time and the date of the GPRS_Pro module from the RTC.It returns ‘1’ on success , ‘0’ or ‘-2’ if errorExample of use:{}GPRS_Pro.setTime(); // Updates time and date2.6. Checking the GSM connectionIt checks if the module is connected to the network for a time desired by the input parameter.If the GPRS_Pro module does not connect within these attempts, function exits with ‘0’.It returns ‘1’ when connected and ‘0’ if not.Example of use:{}GPRS_Pro.check(180); // Waits 180 seconds for connectionAccording to <strong>Libelium</strong> experience, 180 seconds is the recommended timeout for connecting the GPRS network. The timeoutmay vary depending on the network range and quality of service. If the user detects this timeout does not allow his GPRS toconnect, he can experiment with higher values. 180 seconds would be the maximum advised timeout: if the GSM/GPRS modulecannot connect in 2 minutes, it is better to stop trying and check again in the next loop.-10- v0.5
