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
- FRDM-K64F or FRDM-K66F
- WIZnet IoT Shield BG96 board
- USIM card
Example functionality
This example showcases the following device functionality:
1. Import into Compiler
2. Compile and Program
3. If successfully connect to cellular networks(SKTelecom) then you can get below message
Device's Result
