Remote update secondary MCU

[edison_vs_tesla]

I already have some GPIO expanders on my board, but I would rather have a co-processor for my use case.

It would be nice to take another MCU and have my particle board run a OTA update on the secondary MCU.

Just an idea, and I know it's been brought up before. I could work out something with UART and the raw hex for firmware updates. It would be so much nicer if there was support built into particle though.

Hi @edison_vs_tesla take a look at Particle's Asset OTA feature.

There is a GitHub repository with some example projects.

You can find more details in the documentation.

And inside the links Eric mentioned, there are some examples, so if you strategically choose your MCU, you are ready to go:
