Salve a tutti; di solito frequento il sito in Inglese, ma per quanto vorrei chiedere penso che esprimermi e, spero, ricevere risposte nella mia lingua possa essere più semplice e costruttivo.
Scusate se questo messaggio sarà un pò lungo, ma visto che sono stato 'sgridato' per alcuni post senza tutte le informazioni...
E' il mio primo tentativo di approcciarmi alla gestione remota via Cloud di dispositivi (board e sensori) . L'obiettivo, intelligente e compesso , è di comandare il LED_BUILTIN del modulo da remoto.
In IoT Cloud ho creato una 'thing' con una variabile bool LedOn e l'ho associata allla board con le credenziali sicure di accesso, definendo il modulo: ESP8266 LOLIN(WEMOS) D1 R2 & mini sulla porta COM disponibile.
Nell'Editor ho generato lo sketch che riporto qui:
/*
Sketch generated by the Arduino IoT Cloud Thing "TestWemos"
https://create.arduino.cc/cloud/things/db798eae-1f5e-4aea-9d35-f85ba2065c90
Arduino IoT Cloud Variables description
The following variables are automatically generated and updated when changes are made to the Thing
bool ledOn;
Variables which are marked as READ/WRITE in the Cloud Thing will also have functions
which are called when their values are changed from the Dashboard.
These functions are generated with the Thing and added at the end of this sketch.
*/
#include "thingProperties.h"
void setup() {
// Initialize serial and wait for port to open:
Serial.begin(9600);
// This delay gives the chance to wait for a Serial Monitor without blocking if none is found
delay(1500);
// Defined in thingProperties.h
initProperties();
// Connect to Arduino IoT Cloud
ArduinoCloud.begin(ArduinoIoTPreferredConnection);
/*
The following function allows you to obtain more information
related to the state of network and IoT Cloud connection and errors
the higher number the more granular information you’ll get.
The default is 0 (only errors).
Maximum is 4
*/
setDebugMessageLevel(2);
ArduinoCloud.printDebugInfo();
}
void loop() {
ArduinoCloud.update();
// Your code here
}
/*
Since LedOn is READ_WRITE variable, onLedOnChange() is
executed every time a new value is received from IoT Cloud.
*/
void onLedOnChange() {
// Add your code here to act upon LedOn change
if (!ledOn) {
digitalWrite(LED_BUILTIN, HIGH);
} else {
digitalWrite(LED_BUILTIN, LOW);
}
}
Ho verificato e salvato lo sketch: tutto ok (a parte l'assurda occupazione di memoria !):

Ho fatto l'upload e pare che tutto sia andato bene:

Fatto questo, non so più cosa fare., ovvero: dalla Dashboard commuto lo stato della variabile col grazioso interurrore, ma sulla mia board non succede nulla.
Alla pagina Things dell'IoT mi dice che la mia board è OffLine, nonostante lo sketch sia stato uploadato. Durante l'upload i led TX/RX blinkano regolarmente.
Prima domanda (sicuramente stupida, scusate): sul mio PC dove è connessa il modulo, devo avere l'IDE aperto (con lo sketch caricato) oppure dovrebbe funzionare anche senza l'editor locale?
Seconda domanda: la pagina di gestione del mio router TIM non visualizza alcuna connessione WiFi con Wemos: non dovrebbe appararire visto che la connessione in rete pare esserci stata? (oppure viene chiusa immediatamente?)
Terza domanda: al primo avvio, se ricordo bene, della verifica dello sketch ho ricevuto questo alert (io uso Win10 64), ripetuto 4 o 5 volte, ai quali ho sempre dato l'OK:
E' normale che lo ripeta più volte ?
Bene, se non siete ancora stramazzati per terra dopo questa cronistoria, vi ringrazio da subito per qualsiasi informazione utile vogliate darmi.
EDIT 10/07/23
Ho scoperto il Monitor dell'Editor e forse ho avuto qualche indicazione utile, anche se non per me.

Serve questo per capire cosa succede?
Grazie ancora
