Eric Jung / Mbed OS mbed-os-example-cellular-BG96

BG96 Cat.M1 basic sample for WIZnet IoT Shield based on Mbed-OS Cellular APIs (SK telecom network in Korea)

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 and added some features.
