Riccardo_Rizzo:
ok, in this case what you suggest about wait and reconnect after a interval of time could be done, in the following sketch i have modified the connection in the setup (), by adding:
LowPower.attachInterruptWakeup(RTC_ALARM_WAKEUP, NULL, 0);
if (recon > 2 && status != WL_CONNECTED) {
// Serial.println("deepsleep");
digitalWrite(NINA_RESETN, HIGH);
delay(1000);
LowPower.deepSleep(20000);
//delay(1000);
digitalWrite(NINA_RESETN, LOW);
//Serial.println("wakeup");
recon=0;
}
in the example in order to make the wifi1010 in deepsleep mode for 20 seconds, you need to use
**LowPower.attachInterruptWakeup(RTC_ALARM_WAKEUP, NULL, 0);** for wake up the board when the deepsleep time is elapsed, the code example is the following:
/*
This example connects to a encrypted WiFi network (WPA/WPA2).
Then it prints the MAC address of the WiFi module,
the IP address obtained, and other network details.
Then it continuously pings given host specified by IP Address or name.

consider that with 5 V in input the lowest current value reachable is 9.7 mA, with the battery pack is 3/4mA more or less, this should allow you to reduce the consumption in connection phase, in the image the red one is the results with deepsleep mode the green represent the classic connection
Hi Ricardo,
First of all thank you very much for your help, I'm triying your code but I found a problem
error: 'NINA_RESETN' was not declared in this scope
digitalWrite(NINA_RESETN, HIGH);
what does it mean? what is NINA_RESETN?
Thank you very much
