jengbrecht 27:8e6188cbcfd4 14 * SocketModem iCell is a family of carrier certified embedded cellular radio modules with
jengbrecht 27:8e6188cbcfd4 15 * a common hardware footprint and AT command set for built in IP-stack functionality.
jengbrecht 36:bb6b293c7495 16 * This class supports three main types of cellular radio interactions including:
jengbrecht 27:8e6188cbcfd4 17 * configuration and status AT command processing, SMS processing, and TCP/UDP Socket
jengbrecht 36:bb6b293c7495 18 * data connections. It should be noted that the radio can not process commands or
jengbrecht 27:8e6188cbcfd4 19 * SMS messages while having an open data connection at the same time. The concurrent
jengbrecht 27:8e6188cbcfd4 20 * capability may be added in a future release. This class also inherits from IPStack
jengbrecht 27:8e6188cbcfd4 21 * providing a common set of commands for communication devices that have an onboard
jengbrecht 27:8e6188cbcfd4 22 * IP Stack. It is also integrated with the standard Mbed Sockets package and can therefore
jengbrecht 27:8e6188cbcfd4 23 * be used seamlessly with clients and services built on top of this interface already within
jengbrecht 56:e5e5351f14b3 24 * the mbed library.
jengbrecht 36:bb6b293c7495 25 *
jengbrecht 27:8e6188cbcfd4 26 * All of the following examples use the Pin Names for the Freedom KL46Z board coupled with
jengbrecht 36:bb6b293c7495 27 * the SocketModem Shield Arduino compatible board. Please chage Pin Names accordingly to
jengbrecht 27:8e6188cbcfd4 28 * match your hardware configuration. It also assumes the use of RTS/CTS hardware handshaking
jengbrecht 27:8e6188cbcfd4 29 * using GPIOs. To disable this you will need to change settings on the radio module and
jengbrecht 27:8e6188cbcfd4 30 * and use the MTSSerial class instead of MTSSerialFlowControl. The default baud rate for the
jengbrecht 27:8e6188cbcfd4 31 * cellular radio is 115200 bps.
jengbrecht 36:bb6b293c7495 32 *
jengbrecht 27:8e6188cbcfd4 33 * The following set of example code demonstrates how to send and receive configuration and
jengbrecht 62:83ccef1e94db 34 * status AT commands with the radio, create a data connection and test it:
