The blocking thing seems more like a bug to me, but eventually osso_iap_connect should return latest after ~3 minutes due to the D-Bus timeout used. Connectivity works with the following policy in N800: 1) if the requested connection is on, the connect request succeeds 2) if there is no connection on, the requested one is created 3) if there is another connection on, the requested connection is not connected In the majority of cases where applications just ask for any connection, everything works all the time, it's the specific connections that cannot be connected at will. Then there is also the OSSO_IAP_TIMED_CONNECT flag. It must be set if the application triggers a network connection request by itself without user intervention. When this flag is set, case 2) above does not apply, i.e. no application can by itself turn on an (expensive GPRS or CS) network connection. > calling osso_iap_disconnect(...) with OSSO_IAP_ANY or with realIAP > profile name as parameter returns no error but doesn't disconnect > current WiFi connection. Yes. Connectivity policy again. In 770 there was a reference count that disconnected the network connection after the last user exited. As N800 tries to be online as much as possible, the reference count is omitted and the connection does not get disconnected. > I have also tried to disconnect through D-BUS using > disconnect_iap_async() in following code, but it didn't work either. The library is already using that D-Bus interface, so it will work identically. What is the exact use case where policy 3) above jams your application?

trouble to disconnect from WiFi AP
Hi,
In my apllication I'm trying to ensure connection to specific Wifi
network Access Point AP. I'm using osso_iap_connect() call to
connect using previously configured profile and it works well when no
wifi connection is currently selected.
When N800 is already connected to another WiFi AP, calling
osso_iap_connect() blocks application until WiFi connection is
dropped using Connection manager UI.
calling osso_iap_disconnect(...) with OSSO_IAP_ANY or with realIAP
profile name as parameter returns no error but doesn't disconnect
current WiFi connection.
I have also tried to disconnect through D-BUS using
disconnect_iap_async() in following code, but it didn't work either.
Any hint will be really appreciated.
