I don’t think you’d even need the device itself to be connected to the internet for firmware. Your phone connects to the internet, gathers up the firmware, sends it to the device over BT. That’s how my helmet comms work.
If the device is connected to the local network and has some sort of maintenance UI then it might as well. I just don’t want it to be constantly connected or do it on its own.
