FOTA over cellular, is there something similar to mcumgr in Mbed OS?

Hi all,

I’m currently in search of a RTOS for my company to revamp our IOT product, which has STM32 MCU & Quectel (cellular) chip onboard. The device will be installed in the field where FOTA over cellular is an important criteria.

I learned that Zephyr OS has mcumgr support and seems like it is able to perform FOTA over UDP with that tool. I know Mbed OS has ARM Pelion Device Management support out of the box which can perform the FOTA, but I wonder if there’s something in Mbed OS that works similarly as the mcumgr which I can develop my own server to perform the FOTA, among other things?

Thank you.
