ConnMan itself does not run any scan, it requests wpa_supplicant to do so. And it actually requests active or passive scan depending on the context: On the Scan() method it exposes through Technology API: - if there is no known networks configured, it will do only passive scans - if there is 1+ known networks configured, it will first do an active scan on the last connected one, and then a passive scan. Exception: if there is known hidden networks, it will do an active scan for those before the passive one. There are also behaviors on automatic scans for which I don't give details here. Afaik we don't plan to add parameters to Scan() to it would be possible for the user to do a specific active scan. Scanning policies are already quite complicated, to fit all uses-cases, proposing such feature would just bring a bit of this complexity above ConnMan. This would go against the idea, where ConnMan is here to simplify such things for the user and not just wrap wifi features in an API.
