bonjour,
la pioupiou 248 a vu sa pile changée le 05/04
elle a semblé bien fonctionner jusqu'à hier....
dans les event, on voit des démarrages fréquents, sans shutdown....

les messages sigfox sont étonnant dans leur longueur :

"data": "30363b43008384",
"data": "f0",
"data": "1d3b9f41756731303136",
"data": "f0",

une idée, ce problème est-il déjà survenu ?
merci

nicolas

f0 = échec de la localisation

30363b43008384 -> 7 octets, commençant par 3 -> message de monitoring

1d3b9f41756731303136 -> 10 octets, commençant par 1 -> message de startup

@nicolas merci pour les infos de décodage....
la balise s'est remis à émettre correctement après 3 jours d'abscence... peut-être un faux contact au niveau pile...
