Updating multiple Espruino devices

Thanks @Gordon that was definitely my initial question, so a stand-alone application would have to be responsible for connecting and pushing the updates. Makes sense, I was imagining a scenario where the onboard software, as long as it has a BLE connection to any phone, would be able to connect and pull the latest code, even if that meant some remote security feature.

In my case, there is no app, it’s Bluetooth based with a bunch of neopixel functionality and just a connection to a phone/device for sound playback of music, etc.. in this case I figured, what if I wanted to adjust the neopixels to do something else. In this case I couldn’t do that without physical access to the device.
