jengbrecht | 36:bb6b293c7495 | 13 | /** This is a class for communicating with a Multi-Tech Systems SocketModem iCell. The |
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 |
