Thanks, Daniel. This information helped.
My problem is solved.
I was wrong when I said I could not disconnect, I was actually able to do so if
I was connected.
The problem is a result of me not totally understanding the state of "ready" as
opposed to "online". This was explained in a prior email.
What solved my problem is putting timeouts in my test code.
Once I had a timeout (of 30 seconds), I was able to disconnect and continue the
test.
Success, in my test was about 97% to connect to a single access point in a test
I ran for 48 hours.
So I'd say that connman is doing what it claims that it's doing.
Frederick

What kind of hardware are you using? And are you using nl80211 interface
with wpa_supplicant? Is the driver in mainline or is it something closed?

wpa_supplicant is coalescing state signals, and ConnMan has to guess
what is happening. The above message says, wpa_supplicant is likely to
switch to a different AP (roaming) but doesn't tell us.

That is correct if we really roam around.

Not sure what happens here. Can you post the exact steps?

Hard to tell. Any logs?

If ConnMan says it is only you should be able to disconnect. If that is
not possible something is broken. Logs?

Can you run 'monitor-connman' along side and post the log.
Thanks,
Daniel
