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

### Selecting socket type (TCP or UDP)
-You can choose which socket type the application should use; however, please note that TCP is a more reliable tranmission protocol. For example:

+### Turning on the tracing and trace level
+
+If you like to add more traces or follow the current ones you can turn traces on by changing `mbed-trace.enable` in mbed_app.json
+
+```"target_overrides": {
+ "*": {
+ "target.features_add": ["LWIP", "COMMON_PAL"],
+ "mbed-trace.enable": false,
+```
+
+After you have defined `mbed-trace.enable: true`, you can set trace levels by changing value in `trace-level`
+
+ ```"trace-level": {
+ "help": "Options are TRACE_LEVEL_ERROR,TRACE_LEVEL_WARN,TRACE_LEVEL_INFO,TRACE_LEVEL_DEBUG",
+ "macro_name": "MBED_TRACE_MAX_LEVEL",
+ "value": "TRACE_LEVEL_INFO"
+ }
+```

### Board support
The [generic cellular modem driver](https://github.com/ARMmbed/mbed-os/tree/master/features/netsocket/cellular/generic_modem_driver) this application uses was written using only a standard AT command set. 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). For more details, please see our [Mbed OS cellular documentation](https://os.mbed.com/docs/latest/reference/cellular-api.html).
