Hi Hoang Pham,
I am using java 64b.
I train and upload a profile to the Cloud using the “emotiv xavier control panel 3.3.3”. Then I check the correct loading of the profiles on the Cloud and read them by calling EC_GetAllProfileName() and EC_ProfileNameAtIndex().
After this, I use the java example SavingAndLoadingProfileCloud.java configured in profile loading. The login works sucessfully however the profile loading fails systematically. The loading does not fail if no training has been done.
