For those reading my posts about Spark and Wifi... I found an interesting info about 802.11d which is the mecanism used for worlwide roaming, i.e. allowing the clients to stick to the logal regulatory domains broadcasted by access point.
http://hub.silexamerica.com/unwired/unwired/802-11d
short : 801.11d is not allowed anymore by FCC since 2015/16
My RC is broadcasting its country code (so still doing a form of 802.11d) , and this code is set to US (while I'm in France).
My guess is that this is probably the case for All RC worldwide (I'm really still waiting for your regdoms info to confirm that hypothesis).
I believe this because that would be the way DJI implement easily the FCC conformance by setting it fix to FCC. Also, this would be an issue because in countries/devices that still use/allow 802.11d, the wifi client will try to use this US code (and the device itself should actually use another regulatory domain while still saying it is under US which of course would confuse third party devices)
This also mean that the Spark should not be relying on this to get it's own regulatory domain (or at least it should not legally in US), so if the FCC conformance is not flawed, Spark must rely on something else to set it's regulatory domain.
