tu as regardé du coté de la documentation des [ESP](https://docs.espressif.com/projects/esp-at/en/release-v2.2.0.0_esp8266/AT_Command_Set/index.html)?

Ce n'est pas un souci pour le moment mais il faut toujours procéder par soustraction avec le temps

```arduino
    while (millis()-time < timeout)

```

Quel est l'erreur que tu récupère et surtout sur quel commande?

Ton code ne fait rien ou à moitié, tu envois une taille d'un buffer que tu va envoyer, mais tu envois rien, c'est normal?

Tu as essayé la commande "AT+HTTPCLIENT" ?

Certes, mais ce n'est pas le code que tu propose après.  
Il est difficile de pouvoir t'aider, si le code que tu montre n'est pas chronologique et celui que tu utilise.

Donc j'en conclue que tu as réglé tout tes problèmes.

du coup j'ai ca maintenant :

```cpp
 String cmd1 = "AT+HHTPCLIENT= 3\,0,\"http://x.x.x.x/post-sensor-data.php/\",\"http://x.x.x.x\",\"/post-sensor-data.php\",1,\"distance=10\"";
  //Serial.println(cmd1);
  esp8266.println(cmd1);

Il y a un H en trop au moins

AT+HHTPCLIENT=3..

L’adresse IP est sur le loop back??

ah oui j'avais pas vu merci . si j'ai bien compris la question j'utilise juste le localhost(127.0.0.1) il faut que je la mette sur le loopbaack? si cela fonctionne je mettrais sur le serveur de webhost00.

j'ai pas bien compris, désolé. c'est à dire qu'il faudrais prendre l'adresse ip qui est généré par le code pour l'ESP?
