IvI have this functions in my loop() and it publishes temperature reading to Ubidots(an IoT cloud service) using the #include <Ubidots.h> library but it seems it returns a boolean and so the loop is delayed until a true or false value is return and this takes a while there by slowing down my loop() function and other functions in it. Is there a way I can call this function without it having to slow the loop?
