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.

B4X:

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

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

Click to expand...

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

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.

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.

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)?
