SUNGTAE KIM / Mbed OS mbed-os-example-cellular-BG96-TCP

Set specific IP Address/Port

Overview

This code could be access via Cat.M1(BG96 module) of SK telecom network in Korea. Need a WIZnet IoT Shield BG96 board and development board. The code forked Daniel_Lee's mbed-os-example-cellular-BG96 repository(https://os.mbed.com/users/Daniel_Lee/code/mbed-os-example-cellular-BG96/) and added some features.

This example is known to work great on the following platforms:

 This particular cellular application uses a cellular network and network-socket APIs that are part of [`mbed-os`](https://github.com/ARMmbed/mbed-os).
 
-The program uses a [generic cellular modem driver](https://github.com/ARMmbed/mbed-os/tree/master/features/netsocket/cellular/generic_modem_driver) using an external IP stack (LWIP) standard 3GPP AT 27.007 AT commands to setup the cellular modem and registers to the network.

 After registration, the driver opens a point-to-point protocol (PPP) pipe using LWIP with the cellular modem and connects to internet. This driver currently supports UART data connection type only between your cellular modem and MCU.

-The [generic cellular modem driver](https://github.com/ARMmbed/mbed-os/tree/master/features/netsocket/cellular/generic_modem_driver) this application uses was written using only a standard AT command set. It uses PPP with an Mbed-supported external IP stack. These abilities make the driver essentially generic, or nonvendor specific. However, this particular driver is for onboard-modem types. In other words, the modem exists on the Mbed Enabled target as opposed to plug-in modules (shields). For more details, please see our [Mbed OS cellular documentation](https://os.mbed.com/docs/latest/reference/cellular-api.html).
