I have a project based in arduino. Sometimes, when I turn on the system, it cannot connect properly with cayenne´s server. In those cases, it stops in sentence “Cayenne.begin(username, password, clientID);” and, obviously, the whole project doesn´t run.
is it possible to include (in arduino receipt) something after “Cayenne.begin(username, password, clientID)” in order to know it the connexion is ok (or not) and repeat it until get this connexion?.
Another question: is it possible to send a short text message from arduino to cayenne and show it a text box in the app?
Thank you in advance.
