With respect the OTA upload failing Oak that I have been trying to debug (as described in this ongoing thread), add the following information to the list of behaviors:
This Oak DOES NOT report the online spark/status and oak/devices/stderr via the Particle Cloud API as seen in the example below which is from a working Oak when powered up.
event: spark/status
data: {"data":"online","ttl":"60","published_at":"2016-08-17T23:39:49.700Z","coreid":"d9Removed for public consumption"}
event: oak/devices/stderr
data: {"data":"Config Mode","ttl":"60","published_at":"2016-08-17T23:39:50.646Z","coreid":"d9Removed for public consumption"}
