Connect to Mult-Wifi (Hidden SSID) using Blynk on esp8266

There’s quite a few topics on hard-coding multiple SSIDs, maybe this is the simplest to run with…

I want to share my decision. I use this code if, for example, I take the device from home to work where there are different wi-fi networks, or if I want to connect on the street, I simply distribute wi-fi from a mobile access point on my phone. Please note that if none of the listed networks is still connected, the program will still work offline, unlike the standard Blynk.begin (auth, ssid, pass); If there is a solution easier and more interesting I will be glad to discuss. :slightly_smiling_…

Ok , I tried this on my test sketch and I’m happy to report that this indeed works, with hidden SSID’s too !!

My only gripe is this

while (!Blynk.connected() && ssid_count<ssid_mas_size);
if (!Blynk.connected() && ssid_count==ssid_mas_size) {
Serial.println("I could not connect to blynk =( Ignore and move on. but still I will try to connect to wi-fi " + String(ssid[ssid_count-1]));
}

with this,even if it doesn’t connect to Blynk Servers it stays connected to that Access point (“Ignore and move on. but still I will try to connect to wi-fi”) . Somewhat defeating the whole purpose of redundancy (Connect to the access point that has internet connectivity or else try the next one ).Any ideas for this ?
