It's about time
rick merritt   7/16/2013 1:58:17 PM
I did not realize Android was the last major OS yet to support BLE. This is a significant enabler for many peripherals and IoT apps and as such overdue.

Is there any sense Android is falling behind in the latest features in any other area?

Very informative blog, Svenn -- thanks for the background.  And I completely agree with your conclusion that Google's long-stalled buy-in will fuel the "appcessory" market.  Looks like I'll have to get used to using another made-up word, despite the three consecutive consonants. ;-O

It's the only example I can think of where Google is way behind the times, and at least for some users, Android's lack of support for BLE has created some ill will. Here's a simple example close to home. My wife and I both wear FitBit pedometers to track our activity, as part of our fitness programs. When we first got them, she was quite disappointed to find out that her Android phone couldn't sync with her FitBit, but my iPhone could sync with mine. She asked why and I explained it. She found it hard to believe that Google was taking so long to do something that Apple was already doing. I told her don't worry, they will fix this in the near future, probably before you get your next Android phone. "They better," she said, "otherwise I think I might switch to an iPhone."

I've been waiting for this one for a while as well. A couple of friends of mine are working on a device uses Bluetooth, and they were very interested in LE for it. They asked me about Android support and my response was that it almost certainly supported it. Unfortunately, I was wrong. This announcement gives me a chance to recover some of my dignity!

(in answer to rick merritt's query)

No, not that I've ever heard of.  Android leads other mobile platforms in many (if not most) areas.  Lack of cohesive BLE support has stood out as an unexpected exception to this rule (support is available on many newer devices, but only through vendor provided rather than Google provided libraries).  Good to see it is being addressed.

Looking forward to the possiblities

Hi Svenn-Tore, So glad to see this blog. As you know, I've been following Nordic's work with Bluetooth LE and ANT with great interest for years. As a huge Bluetooth fan, I'm already looking forward to the possibilities. With the increasing cost of health care, especially in the US, the medical applications will, I suspect, essentially become life savers. It makes me smile when technology can really help people (rahter than just entertain us or make us more productive).

Android 4.3 with Bluetooth low energy now released
Steve.K   7/26/2013 4:29:44 AM
Google had announced this week that Android 4.3, Jelly Bean, has now been launched with Bluetooth low energy (Bluetooth Smart) support. Devices like Nexus 4 and Nexus 7 (2013 edition) are now Bluetooth Smart Ready. See http://www.android.com/about/jelly-bean/

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.
