In a deployment topology where no device is assigned the gateway role (e.g. all Xenon), what firmware update methods will be available other than physically connecting a host computer to each device? Is there mesh-only firmware update functionality? For example, once a single device receives a new firmware update, all other devices that participate on the same mesh network can be updated.
To be clear, we’re trying to understand how useful the Xenon product is when deployed to environments without internet connectivity or otherwise outside the Particle ecosystem.
