good article. Can't wait for the next one. Now I know that even though two bluetooth devices aren't connected they still can exchange information. This would be good for doing lot's of things other than authentication like... would you have an idea of what could be done with this extra info?

BLE Broadcasting mode comes handy in cases when data could be sent with out acknowledgment, e.g. applications like proximity key fobs etc.

Is there a way you can write how this can be interfaced for Android embedded development?

Unless you want to deal with some kind of attachment to the phone, the short answer is to wait until phones start supporting Bluetooth 4.0 – first phones with new Bluetooth IC are expected at the end of this year. Good thing BLE is an integral part of Bluetooth specification and its proliferation into cell phones is just a matter of time.

First WiFi rolled out WiFi direct a facility already provided by BlueTooth devices. Now BlueTooth is Moving to IEEE802.15.4 space. I think these three has to converge in single SoC at one one time you are going to use one (Atleast in Mobile Devices not in low cost low power sensors)

As you have specified the advertising interval range as 20ms to 10s, is their any defined scanning interval range?

This is a good start, but it's missing a lot of important information for developers. I found this BLE Advertising primer to have some more details of advertisements in BLE, how they work, how they're defined and how to reduce power consumption which is a huge problem for me.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
