Firebase - 1er pas - bug:-(

thmare · April 24, 2022, 11:48am

hello , débutant, je bloque sur un problème (désolé si c'est peut etre qu'une bétise )mais je ne trouve pas la solution (apres des heures de recherches )
mon matériel : Nodemcu et esp8266 wifi

voici mon code récupéré de ce site avec 2-3 modif au niveau du Wifi

mon but : arrivé à me connecter à firebase, quand j'y serai arrivé, faire ce 1er projet sonde température
ex: Send Real-Time Sensor Data to Google Firebase with ESP8266

merci pour votre aide

1er problème, quand il ne trouve pas le wifi, il ne tente pas un nouvelle connection

2eme problème, quand il se connecte au wifi, j'ai ce message d'erreur

"13:41:48.364 -> Connexion WiFi etablie
13:41:48.364 -> => Addresse IP :
13:41:48.364 -> (IP unset)
13:41:52.943 -> Firebase ok

Bonjour @thmare et Bienvenue !

Planquer ce genre de question dans le Bar n'est pas vraiment dans ton intérêt !!

je déplace ce fil de discussion dans la partie principale du Forum Francophone

Pour information l'excellent site RandomNerd Tutorials propose plusieurs tutoriels associant Firebase et ESP6266

8266 Firebase

Il me semble que la phase de connection au point d'accès ET obtention d'une adresse IP y est mieux gérée que dans le code que tu as trouvé, code plutôt approximatif dans sa façon de faire les choses avec comme conséquence de donner un résultat aléatoire.

Un tutoriel tel que celui-ci : ESP32/ESP8266 Firebase: Send BME280 to Realtime Database | Random Nerd Tutorials est très didactique.

bonjour , merci pour vos infos

j'ai repris le code et le tuto donné dans votre exemple
Super : le problème de connectionner est ok

Connecting to WiFi ......192.168.1.60
1:24:45.744 -> Token info: type = id token, status = on request
11:24:47.010 -> Token info: type = id token, status = ready
11:24:47.010 -> Getting User UID
11:24:47.010 -> User UID: nBqj4cGPrJMxXDRZg4XV21MpNEw2
11:24:47.478 -> Relative Humidity : 50.60 %RH
11:24:47.478 -> Temperature in Celsius : 19.44 C
11:24:49.494 -> Relative Humidity : 50.62 %RH

Mais, (désolé ) je bloque sur un dernier point .. FIrebase ne réceptionne aucune donnée

je pense que c'est parce que je n'arrive pas à intégrer ces lignes :

// Get latest sensor readings
temperature = bme.readTemperature();
humidity = bme.readHumidity();

// Send readings to database:
sendFloat(tempPath, temperature);
sendFloat(humPath, humidity);

J'ai un capteur capteur temperature SHT30 2.15-5.5V, Interface HY2.0-4P , et je dois utiliser
#include <Wire.h>
#include <Adafruit_Sensor.h>
#include <Adafruit_Sht31.h>

Alors que dans l'exemple c'est un BME280
#include <Adafruit_BME280.h>

Mon code tourne si je de active les 4 dernières ligne mais du coup il n'envoi rien à Firebase ?!
