Android Question Can't connect to hidden WiFi network

[elektor18]

Hi All,

At the moment I'm writing a part of code which should connect android device with hidden network (disconnect existing connection and connect to that hidden one) but it doesn't do that and I don't know why.

Dim wifi1 As MLwifi

   
wifi1.saveWifiAP("MyHiddenWiFi",0,"",True)

So this command should add network to list (and it does) but for some reason doesn't want to connect to it.

HI
Whether this new Wi-Fi network has access to the internet? ...

 

[elektor18]

No it hasn't, why? Does it matter?

 

[kisoft]

Android may not want to connect to a network that does not have internet access. I do not know if you can somehow force him to connect to such a network.
Wait for the opinion of other forum members.

It will connect if I do it manually, doesn't want do it by code. Any ideas?

 

[elektor18]

Can anybody advice? How to force device to connect to router automatically in app?

wifi1.saveWifiAP("MyHiddenWiFi",0,"",True)

saveWifiAP(String ssid, int security, String password, boolean connect) As Boolean

it should return a boolean true.
or maybe its because u not using security and password.
i never used this MLwifi lib.

I will check if that is a problem when I back home after work.
Thanks for now.

Hi
Test it in airplane mode with wifi enabled.

 

[elektor18]

Still the same. There must be way to force it to connect even if there is no protection and no internet access...

If this is a hidden SSID, have you previously saved it to your list of wifi networks?

It may only work if the entry already exists in the list.

 

[elektor18]

Yes, it is saved network

Does it work if the network is not hidden?

 

[elektor18]

No it doesn't want connect anyway, I tried hidden - open, hidden - secured, not hidden - open, not hidden - secured and no luck. In saved network list it is mentioned that this network is saved by my application but that shouldn't effect to this issue, should it? Just to remind, this network hasn't got internet access.

I don't think that it matters that there is no internet connection. You can turn on airplane mode and turn on wireless to see whether it makes any difference.

This code is a bit related: https://www.b4x.com/android/forum/threads/mqtt-chat-network-error.90892/#post-574610
However you need to first connect to the wifi network.

 

[elektor18]

I have tried airplane mode with wifi enabled as kisoft recommended before but no change.

HI
What is this Wi-Fi network? Router, ESP8266?.....

 

[elektor18]

ESP8266

 

[kisoft]

Maybe this is the problem of the ESP8266 module itself?....You have updated the software in this module?...

try this:

I'm using arduino IDE to programming ESP chip so this is ok. How to detect if android device is connected to proper/demand ssid network and wait until that connection is established (eg. few tries to connect, if no success then give up)?
