I have several Spark Cores out in the field at customer locations and after flashing 3 of them with new firmware 2 came back online and 1 has remained offline. The one that was offline was previously connected for 6 days without issues.
So what I’d like to ask the community is: do you reflash devices that are out in the field or is that too dangerous? Is there a failsafe mechanism already in the firmware or should I add something in case the flash takes too long or fails?
What do you do when a device goes offline in the field?
What are you thoughts and experiences with reflashing Cores that are in the hands of customers?
