Datasheet could be expanded with a little more example code in C, but once you got it going it's working very well! When you're using the software to set the board's parameters, don't forget to start the program with administrator rights; otherwise it won't work.
the DFRobot RF Modules (pair) is an excellent communication system and at low cost, we use it to transmit electronic displays data such as temperature, humidity, or text giving very good results
DFRobot RF Modules (pair) est un excellent système de communication et nous l’utilisons pour transmettre des données à afficheurs électroniques telles que la température, l’humidité ou le texte à bon prix
La feuille de données pourrait être étendue avec un peu plus de code d'exemple en C, mais une fois que vous l'avez obtenue, cela fonctionne très bien! Lorsque vous utilisez le logiciel pour définir les paramètres du tableau, n'oubliez pas de démarrer le programme avec les droits d'administrateur. sinon ça ne marchera pas.
Very good product easy to install and configure reach of more than 100 meters 100% recommended
