In collaborative research, developing innovative technologies for education based on cloud computing and data analytics raises ethical issues of different nature. This work discusses ethics related within the implementation of a Smart System with such technologies in eLearning context under the Internet of Things (IoT) paradigm. The system, uses electrocardiogram (ECG) and electroencephalogram (EEG) wearables and computes students' attentional state to perform recommendations to maximize it and thus contribute to the decrease of students' dropout in Universities. Furthermore, it is presented a 6-step procedure solution to solve ethical issues raised by this type of scenario that includes articulation between different actors in a center for supporting students inside the university.
