I am developing a system that will be installed in a remote location that once installed, will be cumbersome to reach (physically access it).
The location has no access to the cloud but will have a network connection to a Xenon and a Featherwing. The current firmware has
SYSTEM_MODE(MANUAL); to avoid cloud disruptions since the cloud will not be reachable anyway.
I would appreciate the community’s input on ways to update the firmware in this case. Of course I can also connect a USB cable to the Xenon and use the flash --serial command but the problem is that the cable length may need to exceed 150 feet.
