Hi,
I've created an soft access point with connman by enabling tethering.
/net/connman/technology/wifi
Name =3D WiFi
Type =3D wifi
Powered =3D True
Connected =3D False
Tethering =3D True
TetheringIdentifier =3D MySSID
TetheringPassphrase =3D TestPassPhrase
I have 2 clients connected to this access point.
Then I want to scan for other WiFi networks. This fails with -> "Device or =
resource busy"
Execution of "iwlist scan" find networks at same time. Why it not work with=
connman scan?
Best Regards
Jan
