Bluetooth SIG Announces Deprecation and Withdraw of Legacy Bluetooth Core Spec Version

Samsung BLE SDK (Bluetooth 4.0)

Quoted from: http://developer.samsung.com/ble

Prior to Android, Samsung has released BLE SDK

 Samsung BLE SDK ^beta

Bluetooth low energy (BLE) is a wireless computer network technology which is aimed at novel applications in the healthcare, fitness, security, and home entertainment industries¹⁾. Compared to "Classic" Bluetooth, BLE is intended to provide considerably reduced power consumption and lower cost, whilst maintaining a similar communication range²⁾.

Samsung BLE SDK allows you to develop your own BLE applications which use the Bluetooth Low Energy Client and Server based Protocols. Developers can utilize rich set of API’s provided by our framework to develop Bluetooth 4.0 based applications.

Architecture

The APIs provided by our sdk gives a set of standard GATT procedures and is generic enough to be used with all Bluetooth LE Client and Server based profiles. Below is the basic architecture of our Bluetooth Low Energy stack and framework.

Samsung BLE architecture uses Bluedroid stack which coupled with Samsung framework provides the developer with wide variety of APIs to choose from and provides greater control over Gatt Services, characteristics and descriptors. The framework exposes distinct client and server based classes which can be imported by the application to implement the BLE profiles.

※This SDK is for Samsung Galaxy devices with Android 4.2 and above.

Use Cases

• 
  Heart Rate Profile(HRP)
• 
  Proximity Profile(PXP)
• 
  Alert Notification Profile(ANP)

Profiles are high level definitions that define how services can be used to enable an application or use case. For further information on these profiles, visit : https://www.bluetooth.org/Technical/Specifications/adopted.htm

Proximity Finder (Lost Finder)~BLE (Bluetooth 4.0) Application

I have evaluated several lost finder products.
To my suprised, the new company called as StickNfind is the one which is the most usful one.
https://www.sticknfind.com/

The design normally is set as working in certain distance far.
Excepting StickNFind, other suppliers proximity finder mostly has misworking happened.
For example, when set alarm at 5M, but start woring in 1M or 2M in actual case.
This problem may due to the interference of mobile, WiFi or other wireless device.

Market Products Testing

Therefore, promixity finder actually not only a works for APP (unfortunately most suppliers think so), but BLE design is also a task to enhance the accurancy! Only with the accurancy, this products may able to spread to consumer market widely!

Google Announces Bluetooth® Smart Ready Support for Android Coming Later this Year

Quoted from: http://www.bluetooth.com/Pages/Press-Releases-Detail.aspx?ItemID=167


Today at Google I/O, Google’s annual developer conference, Google announced that in the coming months, Android will include native support for Bluetooth Smart Ready and Bluetooth Smart devices. Phones and tablets with a dual-mode Bluetooth chip running the coming version of Android will qualify as Bluetooth Smart Ready. Bluetooth Smart Ready is the premium designation for devices that are compatible with virtually any Bluetooth enabled product, from keyboards or audio headphones, to the next generation of ultra power-efficient Bluetooth Smart appcessories, like the FitBit Flex or the Pebble watch, coming to market now.

“Working with the big OS providers to offer native support for Bluetooth Smart Ready has been a major initiative within the Bluetooth SIG – we’re thrilled to welcome Android to the family,” said Suke Jawanda, CMO of the Bluetooth SIG. “It’s the hardware and software support that enables Bluetooth Smart Ready devices to seamlessly connect with the billions of Bluetooth devices in use today, and the exploding new market of Bluetooth Smart appcessories. With today’s announcement, Google joins Apple, Microsoft and BlackBerry in providing native software support which is great news for phone and tablet manufacturers, application developers and ultimately, consumers who count on Bluetooth to connect more of their technology.”

 

The native Android support for Bluetooth Smart Ready technology available in the coming months means Bluetooth Smart developers will have an easy way to connect their devices to and distribute their applications within the massive Android ecosystem. Developers will be able to use the new Android API to feed data collected from Bluetooth Smart appcessories, like fitness monitors or medical devices, to their apps running on Bluetooth Smart Ready products, like smart phones or tablets. Once released, any new Bluetooth enabled phone or tablet running Android and featuring a dual mode Bluetooth radio chip will be Smart Ready.

 

ABI projects the market for Bluetooth appcessories (defined as an accessory device with a companion application) to grow from 220 million units in 2013 to nearly one billion in 2016. To support this growth, the Bluetooth SIG has launched a Bluetooth developer enablement initiative which includes a web portal featuring a community forum, training and other resources to make designing with Bluetooth easier and faster. The Bluetooth Quick Start Kit (available now) serves as an introduction to Bluetooth Smart technology. For the Android developer community, the Bluetooth Application Accelerator (coming soon) will provide detailed implementation and developer guidelines to speed time-to-market for appcessory devices.

 

“The real winner here is the consumer,” adds Jawanda. “Bluetooth is truly the people’s technology – it is recognized, trusted, and can already be found in the end user’s pocket. Additionally, it is the only wireless technology to offer the ultra low power consumption and ubiquity needed to bring connectivity to the millions of appcessories coming to market. The Bluetooth Smart products we are going to see in the coming months are going to make life better, give more insight, and enable us all to make more informed decisions.”
