How are the frequencies set for tethering? Is this possible using
connmanctl, or do I need to speak dbus to access this functionality?
ConnMan is using channel 1 on the 2.4 GHz band when tethering. One
really cannot use any 5 GHz channel without prior knowledge as most of
the 5 GHz channels need to do radar avoidance. And of course the
channels are different around the world. And there still are 2.4 GHz
only devices around.
In a perfect world wpa_supplicant should know which channel to use as it
is the only component with possibly all the data about the radio
conditions and channels to avoid. In a not so perfect world ConnMan
guesses safely and always uses channel 1. The "crowded channel"
-syndrome, if there happens to be any in the location tethering is
enabled, is of course also present on channel 1. Thus ConnMan still
waits for logic to happen on wpa_supplicant side and wpa_supplicant to
be able to pick a channel...
I'm assuming that there's no way to specify
in client mode?
I think it is possible, but if the AP is not on the channel or roaming
needs to take place, it won't connect or roam. So not use there.
