Best ARM Microcontroller for FOA (Firmware Over The Air)

[diyaudio]

Hi

 I`m busy working on a prototype that requires Firmware Over The Air support with "minimal design effort overhead" lets say support out the box?, what microcontroller is best suited for this?

Ack.me modules contain ARM and support OTA updates. They have schemes that allow you to run your own code and the can provide the OTA servers. May  or may not be applicable for your requirements. You can ask them, they are very responsive.

thanks will check it out, doest look like anyone else has experience in this area given the speciality of the topic.

It's a very open question.
ARM can be a cortex M0, where OTA upgrades are not really needed.
To Cortex M4 where it can be a convenience.
Up to an ARM A6, where it is often the only used method.

The memory available will be the key factor in the feasibility of this.

OTA allows to push security updates. After all you have a node that is connected to the internet, uses security protocols and certificates and is subject to volenerabilities.

It doesn't say internet anywhere in the original question.
But it is true, that when you use security, they will eventually expire or contain known exploits.
