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.
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)
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.
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?
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
