Content was between shallow (everything but codecs) and deep (codecs), enthusiastic presenters but after a while the "you know" and "like" are getting really annoying.

Thanks for coursera

OK. the main professor clearly knows his stuff. On the other hand he goes into unnecessary detail and then quizzes you on it even though its not relevant to the course (typical bricks and mortar education type BS). The assistant instructors (likely this guys students) are not as great and the whole thing is amateur night.

Big difference in difficulty between the math-heavy codec theory lectures and the other material which is quite basic. Not much to do with the DragonBoard.

Module about codecs was great.

The rest was too easy. An equivalent to reading manual on internet. No value added :(.

good

The Course is acceptable, however, it should be called, Introduction to VoIP communication or Developing VoIP applications rather than its current title.

Assignments are either super easy or never have a right answer

Personally, I will not recommend this course for other who want to understand IoT
