Re: [android-developers] Re: Connecting to a wifi device from the android application

A scan is active at the framework and in the wpa_supplicant at a certain interval. So, you do not really need to start a scan to connect - but doing an explicit scan may start the connection right away.

I don't know what Reto's book says, but it's just that I've done a bit of work with WiFi on Android and that's my experience...

I don't think you need to call startScan after calling enableNetwork.  Here's what my book says:

To use a particular network configuration, use the enableNetwork method, passing in the network ID to use and specifying true for the disableAllOthers parameter: 

// Get a list of available configurations

 List < WifiConfiguration > configurations = wifi.getConfiguredNetworks();

 // Get the network ID for the first one. 

if (configurations.size() > 0) { int netID = configurations.get( 0). networkId;

 // Enable that network.

 boolean disableAllOthers = true;

 wifi.enableNetwork( netID, disableAllOthers);

 }

That's half of it. The other half is calling WifiManager.startScan() to actually trigger the {re}connect.

I think you call this function in WifiManager:

boolean

enableNetwork(int netId, boolean disableOthers)

Allow a previously configured network to be associated with.

My application (supports 2.2 and later) needs to connect with a wifi device like FlashAir after scanning networks using WifiManager.

Is it possible to connect to a device from the application ? or is it only possible by scanning and connecting devices from settings?
