8.4.3 FORMAT BOOLÉENNE
Une donnée booléenne est un type de donnée possédant, essentiellement, deux valeurs : 0 ou 1, ou vrai et faux, 0 étant le faux et 1 étant le vrai.
Le protocole MQTT aussi bien que le logiciel NXperience acceptent que, selon le critère défini par l'utilisateur, les valeurs booléennes soient
présentées en format numérique ou en format de chaîne de caractères (string).
Le paramètre Format Booléenne du NXperience (voir la section
variables booléennes seront présentées dans la trame JSON, selon les exemples ci-dessous.
