great question, as usual, Chip.
Option 1: Raspberry Pi + Particle CLI
Could a Raspberry Pi be used here?
If one can install the Particle CLI in it, you could potentially use a script that runs when the rasp pi boots and calls the CLI to flash the firmware.
Very Park Ranger friendly:
- connect via usb to the boron
- power up
- wait a minute and/or observe the boron go yellow then back to online mode breathing cyan
Option 2: Raspberry Pi + NEOPO
@nrobinson2000 will be in better position to confirm if you could use neopo for this as an alternative to the Particle CLI.
EDIT:
Option 3: Do they have laptops?
If they do, an Electron app that wraps chrome or the Particle CLI can
Those are some options I can think of today
Cheers!
