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
include the mbed library with this snippet

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).
