ESP VROOM deep sleep fonctionne à moitié

**J4e8a16n** · 14/12/2019, 20h05

Bonjoursà tous,

Voilà , à partir d'un code qui fonctionne parfaitement (même à plus de 30 mètres) , Le sketch lit un fichier SPIFFS le place dans un 'array' et
la fonction loop publie les données actuelles puis
publie les informations du fichier en sens inverse pour avoir les données récentes en premier.

J'ai tenté d'ajouter le deep sleep à la fin de setup.

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
    esp_sleep_enable_timer_wakeup(TIME_TO_SLEEP);
  esp_sleep_enable_timer_wakeup(TIME_TO_SLEEP * uS_TO_S_FACTOR);

Et à la fin de la fonction loop:

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

  esp_deep_sleep_start();

La carte s'éveille à chaque 2 minutes.Et là ça craint, puisque le code du setup s'exécute mais que la fonction loop ne semble pas fonctionner.
Voici le output du fichier quand il est vide:

   DHT11-DHT22 Sensor with Arduino - Random Nerd Tutorials.zip
   Rui Santos
   Complete Project Details http://randomnerdtutorials.com
  -------------------------------
So, my measurements show that the wake-up time for a 
8MHz Arduino is ~1.95ms. And it perfectly matches the 
datasheet, as it states the Start-up Time from Powerdown 
and Power-save is 16k CPU cycles for a crystal oscillator,
2ms with the 8MHz crystal. Arduinos with 16MHz clocks 
should have the wake-up time of around 1ms.

J’avais raté le code - mais ça ne me dit pas pourquoi vous avez ces 2 lignes ? Surtout la première

Exact. J'ai pris ce lignes quelque part sans remarquer qu'elle faisaient la même chose.

Avec deep sleep les variables RTC sont effacées, pas avec light sleep;
Voici la dernière version qui fonctionnait à peu près bien.:

Je vous reviendrai avec la version finale ... plus tard.
