Just a point of clarification; the term "advertising" is a Bluetooth SIG/Spec term and does not refer to commercial advertising. It might be best to substitute the word "broadcasting" as this is essentially what these reference designs do; they transmit information (compliant with Bluetooth SIG specifications) without regard to which or how many devices can or want to hear what they are transmitting. As mentioned in the article, this is similar to the way radio and broadcast TV operate.
