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:

Requirement

  1. FRDM-K64F or FRDM-K66F
  2. WIZnet IoT Shield BG96 board
  3. USIM card

Example functionality

This example showcases the following device functionality:

1. Import into Compiler
