4.7.3. Reading SMSs
The
readSMS()
function reads an SMS from the module storage. The user must give the index of the SMS to be
read from memory. In the case a new SMS is received, all SMS related parameters are stored in the Waspmote’s
library structures: index number, status, sender number, date and time. The SMS text field can be found in
_4G._
buffer
.
Example of use:
{
uint8_t index = 5;
_4G.readSMS(index);
}
The
readNewSMS()
function reads the last unread SMS received by the module. There are 2 function prototypes:
with or without timeout. If the user needs to wait for a new text message for a period of time, the timeout must
be specified as input. If no input is defined, the request for new text messages is instantly performed. In the case
a new SMS is received, all SMS related parameters are stored in the Waspmote’s library structures: index number,
status, sender number, date and time. The SMS text field can be found in
_4G._buffer
.
Example of use:
{
_4G.readNewSMS(30000);
}
