Example for TCP socket over WiFi on Nuvoton's Mbed CE enabled boards

This is an example to demo TCP socket over WiFi on Nuvoton's Mbed CE enabled boards.

Check out Mbed CE for details on Mbed OS community edition.

Support development tools

Use cmake-based build system. Check out hello world example for getting started.

⚠️ Warning

Legacy development tools below are not supported anymore.

• Arm's Mbed Studio
• Arm's Mbed CLI 2
• Arm's Mbed CLI 1

For VS Code development or OpenOCD as upload method, install below additionally:

• NuEclipse: Nuvoton's fork of Eclipse
• Nuvoton forked OpenOCD: Shipped with NuEclipse installation package above. Checking openocd version openocd --version, it should fix to 0.10.022.

Developer guide

In the following, we take NuMaker-IoT-M467 board as an example for Mbed CE support.

Hardware requirements

• NuMaker-IoT-M467 board
• Host OS: Windows or others
• WiFi ESP8266

Build the example

1. Clone the example and navigate into it

   $ git clone https://github.com/mbed-nuvoton/NuMaker-mbed-ce-wifi-tcp-example
   $ cd NuMaker-mbed-ce-wifi-tcp-example
   $ git checkout -f master
   

2. Deploy necessary libraries

   $ git submodule update --init
   

   Or for fast install:

   $ git submodule update --init --filter=blob:none
   

3. Compile with cmake/ninja

   $ mkdir build; cd build
   $ cmake .. -GNinja -DCMAKE_BUILD_TYPE=Develop -DMBED_TARGET=NUMAKER_IOT_M467
   $ ninja
   $ cd ..
   

Flash the image

Flash by drag-n-drop built image NuMaker-mbed-ce-wifi-tcp-example.bin or NuMaker-mbed-ce-wifi-tcp-example.hex onto NuMaker-IoT-M467 board

Verify the result

On host terminal (115200/8-N-1), you should see:
