Data from MetaWear are not updated RT

I have just started experiment with the MetaWear and tried the MetaWearApiTest from github. Unfortunately, I am not able to see the data updating real time. Whenever I am pressing a button in the DetailViewController i.e. "Read Temperature",  the UI label is updated after ~20s or more. Same with the accelerometer graph - the values are added to the graph after a while. After adding debug output in the acquisition loop of the accelerometer, I can see that the values are constantly updated, but the UI is not updating. I am using an iPhone 4s. Are you experiencing similar issues?
Could you elaborate on this? Is there a way that I could synchronously see the data acquired in the UI?
