Important changes to repositories hosted on mbed.com

Mbed hosted mercurial repositories are deprecated and are due to be permanently deleted in July 2026.

To keep a copy of this software download the repository Zip archive or clone locally using Mercurial.

It is also possible to export all your personal repositories from the account settings page.

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.
