Bonjour, avec le code, la valeur en gramme est limitée a 65635 ( a peu pres), pour ne plus avoir cette limitation, il faut modifier uint16_t en uint32_t pour le payload weight a 2 endroits dans l'ino et aussi modifier le callback dans le backend sigfox `//TIME https://github.com/PaulStoffregen/Time

Bonjour, j'envoie en centaine des grammes du coup je suis large

Bonjour, j'envoie en centaine des grammes du coup je suis large

pourtant avec le code d'origine, quand ma ruche dépasse les 65635 grammes, ca repasse a 0 un exemple, ca passe a 0, un gros lot d'abeilles sort, ca repasse a 65xxx et quand ca rentre, ca repasse a 0 et +

[Rastafouille]

Salut, oui dés que tu dépasses 65635 ca redémarre a zéro, normal, divise tout par 10 ou 100.
