Daniel Lee / Mbed OS mbed-os-example-cellular_BG96_os511

This is an example based on mbed-os cellular APIs that demonstrates a TCP or UDP echo transaction with a public echo server. Especially, BG96 operation check based Mbed OS 5.11, tested via SK Telecom in Korea

This code could be access via Cat.M1(BG96 module) of SK telecom network in Korea. Need a WIZnet BG96 board and development board. Before using this code, must be checking your modem is authorized or not from SK telecom. This code is based on Mbed OS 5.11.5.
