Android Question Slow switchover from one AP to another

[ardhuru]

Hello,

My phone is by default connected to the home router "Andromeda".

My app needs to switch the connection to another AP, an ESP8266 configured as an AP "ESP_Blue". On exiting the app, the phone needs to re-connect with the home router.

I use the excellent library jhwifi ver 1.2 to do the switching.

Sub Activity_Create(FirstTime As Boolean)
   
    jhw.Initialize()
'    'n=jhw.findConfiguredNetwork("Andromeda")                    'For STATION MODE
    n=jhw.findConfiguredNetwork("ESP_Blue")                    'For SOFTAP MODE
    jhw.startscan()
    timer1.Initialize("timer1", 2000)
       timer1.Enabled = True

Sub timer1_Tick
   Dim n As Int
   n=jhw.findConfiguredNetwork("ESP_Blue")
   Log("ESP_Blue: " & n)
   ' Connect to network
   jhw.enableNetwork(n, True)
End Sub

And to disconnect, and connect to the default router on exit:

Sub ButtDisc_Click
   
    WiFi_Socket.Close
    TcpStreams.Close
    ButtDisc.Text = "Disconnecting.."
    TTS1.Speak (ButtDisc.Text,True)
    Activity.Finish
   
    'THIS AUTOMATICALLY CONNECTS BACK TO THE HOME ROUTER
    jhw.Initialize()
    n=jhw.findConfiguredNetwork("Andromeda")
    jhw.enableNetwork(n, True)
   
End Sub

Now, when I run the program, it takes quite a while for it to connect to the ESP_Blue. Could be a anything from 10 to 20 seconds, at times its fast enough at about 5 seconds.

When I quit the program, the phone reconnects to the home router immediately.

The ESP_Blue module is not to be suspected (I think), it shows a robust operation, and I can connect to it very fast from outside my app, manually.

Am I using the jhwifi library in an incorrect manner? Or is it something else?
