Value of %iswifi% variable

[mackowiakp]

What does it mean value of %iswifi% system variable?
In my case it shows "7".
Does it mean that if value is grater then "0" that mean that WiFi is connected and when equal "0" disconnected?

Yes and no

It is a set of bits.
These are the bit positions (taken from WiFiEventData.cpp)

Code: Select all

#define ESPEASY_WIFI_CONNECTED               0
#define ESPEASY_WIFI_GOT_IP                  1
#define ESPEASY_WIFI_SERVICES_INITIALIZED    2

Thus:
0 = disconnected
1 = Connected
3 = Got IP && Connected
7 = Got IP && Connected && Completed to set all flags WiFi is initialized.

Other values can occur, but shouldn't. (at least not for long)
