bonjour
toujours dans la galèrrrrrrrrrrre
j’ai une arduino rev 3 avec une grove base shield v2 dessus. il y a 3 capteur grove dessus un dth11 un barometre un un capteur de luminosité. j’ai relié un rn 171 dessus. le rn s’associe avec mon réseau wifi.
le code sur arduino fonctionne sur le moniteur série j’ai les résultats qui s’affiche.
pin arduino 3.3 v sur 3.3v rn
pin gnd sur gnd rn
pin rx sur tx rn
pin tx sur rx rn
sur le rapsberry, j’ai un serveur lighhtpd qui tourne si j’envoie <? php echo "grrr";?>, cela fonctionne mais dès que j’envoie le code ci dessous rien ne s’affiche et nada dans la base de données. Ma requete get est set com remote GET$/rnpl.php?value1=temperature&value2=pressure&value3=Rsensor&value4=h
voici les différents codes si quelqu’un voit une erreur.
merci

je suis trop mauvais sur ce coup…
:.compris. Donc, si je résume :
