MCUMGR SMP implementations

Rodrigo Peixoto

Hi all.

My company is developing two boards let's call them Board A and Board B for illustrating purpose. Board A is simple it has some sensors and it has a shell interface for communicating with the other one. Board B is the "gateway" and has Internet connectivity through the Cellular network. They had to be created separately.

We need to upgrade the firmware of both boards in the field. For now, Zephyr only supports FOTA over Bluetooth and Shell/UART, right? So I guess we'll need:
1 - to create a Shell SMP Client at Board B that will be able to upgrade the firmware of Board A using a version of the firmware received by the internet;
2 - to implement a different SMP Server at Board B to receive its own firmware by the Internet as well. 

Do you have any start point, tips, something that could help here? 

The future plan, after I made customs SMP Client and Server, is creating an SMP Server over Bluetooth Mesh. In another project, we will need that. Is anybody working with it already?  

Thank you.
