Nuvoton / Mbed OS NuMaker-mbed-cloud-example-Ethernet

Simple Mbed Cloud client application for NuMaker-PFM-M487 and NuMaker-PFM-NUC472 over Ethernet.

This application contains the example codes to:

1) Connect PFM-M487/PFM-NUC472 boards to Pelion

2) Enable Firmware update

For storage, PFM-M487/PFM-NUC472 support both SPI interface SD and built-in SD bus SD.

For connectivity, PFM-M487/PFM-NUC472 support Ethernet (on-board) by default.

This example supports Ethernet and built-in SD by default.
