For the first time, Sitara ARM MPU-based devices can leverage pre-integrated, community-backed mac80211 Wi-Fi and BlueZ Bluetooth drivers for cost-effective access point applications
DALLAS, July 11, 2011 – Texas Instruments Incorporated (TI) today premiered its first module platform housing the WiLink 6.0 (WL1271) single-chip, wireless combo solution with TI’s open source, Linux-based OpenLink drivers. The OpenLink drivers are built on the community-validated mac80211 Wi-Fi driver and BlueZ Bluetooth protocol stack. The first in a series of such open source platforms from TI, the new WiLink 6.0 OpenLink platform is pre-integrated with TI’s AM18x Sitara ARM microprocessors (MPUs). This enables customers developing industrial or point-of-service applications on cost-effective ARM MPUs to easily introduce reliable, low-power Wi-Fi and Bluetooth wireless technologies.

Introducing OpenLink Wi-Fi access points
Today’s release also signifies the first time TI’s customers can easily repurpose Sitara ARM MPU-based designs as Wi-Fi access points via the new WiLink 6.0 OpenLink platform. OpenLink technology offers mobile-grade, battery-optimized Wi-Fi connectivity supporting native Linux designs, giving customers tested wireless technologies that can be easily re-integrated into designs as they migrate from one kernel version to the next. Additionally, TI’s mac80211 Wi-Fi driver is optimized to maximize system level throughput.
As a result, battery-friendly customer products built on Sitara ARM MPUs can serve as a mobile Wi-Fi gateway or support peer-to-peer file transfers with other Wi-Fi enabled devices. These capabilities eliminate the need for external access points and create new opportunities for unique use cases depending on mobile, self-networking devices.

Two-chip bundle costs less than $1.00, enables long-range wireless connectivity for cost-sensitive, low-power applications such as toys, security systems and more
DALLAS (July 7, 2011) – Texas Instruments Incorporated (TI) today introduced a new Sub-1 GHz RF Value Line family, offering developers low-cost connectivity solutions for sub-1 GHz RF applications such as remote controls, toys, home and building automation, and security systems. The Sub-1 GHz RF Value Line family launched with the CC115L transmitter, CC113L receiver and CC110L transceiver, all available immediately. In high volume, the line offers a complete, one-way RF link for less than USD $1. The new devices are based on TI’s Sub-1 GHz CC1101 RF technology, and are pin-, register- and code-compatible, as well as backwards compatible with existing sub-1 GHz systems. For more information, see www.ti.com/rfvalueline-pr.
“TI’s new Sub-1 GHz RF Value Line answers the market’s increasing need for simple, low-cost connectivity for applications that require both long battery life and long range wireless connection,” said Erling Simensen, product marketing manager, Low-Power RF, TI. “Designs based on the Sub-1GHz RF Value Line family not only ease connectivity integration efforts for engineers, but promise wireless connectivity for more of today’s cost-sensitive consumer applications.”
The CC11xLDK-868-915 and CC11xLEMK-433 development kits provide complete hardware performance testing and software development platforms for the new product family. The kits also offer new low-cost reference designs, with a compact PCB antenna for 433, 868, 915 MHz, featuring a reduced component count and complete design ready for FCC and ETSI certification. The small-size, compact PCB helix antenna represents only a quarter of the size of previous PCB antennas, and is useful for applications requiring high antenna efficiency in a compact area.

The ability to find missing keys and smartphones, or alarm and securely lock almost any portable device that is separated from its owner, will be just the start of a new wave of proximity-based wireless sensing applications that the newly adopted Bluetooth low energy Find Me and Proximity profiles will allow as part of the latest Bluetooth v4.0 spec
Oslo, Norway – JUL 5, 2011 – Ultra low power (ULP) RF specialist Nordic Semiconductor ASA today announces that the Bluetooth SIG’s recent finalization of its Bluetooth low energy Find Me and Proximity profiles – part of the latest Bluetooth Version 4.0 (v4.0) specification – will make mass-market wireless proximity and security sensing viable for the first time.
This will include the ability to find missing keys and smartphones, or alarm and securely lock almost any portable device that is separated from its owner (or authorized user) by more than a certain distance via the use of, for instance, a simple Bluetooth low energy key fob device.
Within the latest Bluetooth v4.0 specification, that includes Bluetooth low energy as a hallmark feature, there are now two profiles applicable to proximity sensing and security:
- The Bluetooth low energy Find Me profile targets smartphone applications, and will allow users to pair small – but commonly misplaced – everyday objects with their smartphone in order to locate them. One early product example will be Bluetooth low energy key fobs that users will be able to use to find a misplaced phone (by pushing a button on the fob to make the phone sound an audible alert), or a misplaced key fob (by pushing a button within a smartphone app to make the key fob sound an alert).
- The Bluetooth low energy Proximity profile targets smartphones and other portable devices such as computer laptops and tablets, and further extends the functionality of the Find Me profile to include more advanced in- and out-of-range functions. This could include, for instance, the ability to trigger an automatic security lock-down if a smartphone or laptop/tablet is separated from its owner by more than a certain threshold distance, or wake a sleeping desktop computer as soon as the user sits down in front of it.
“The profiles have been developed within the Bluetooth SIG PUID [Personal User Interface Device] working group by technical teams from a number of different Bluetooth SIG member companies all eager to enable this new, standards-based wireless functionality,” comments Frank Berntsen, Chief Scientist at Nordic Semiconductor and chair of the PUID working group.
“I can foresee a day when proximity sensing will become a standard feature of almost all modern portable electronics – from car key fobs to smartphones and laptops,” comments Michael Foley, Ph.D., Executive Director of the Bluetooth SIG. “And with Bluetooth v4.0, manufacturers can go beyond the devices we know and carry today, to create personal security products that keep our children safe, our pets nearby, and our valuables within reach. The adoption of these profiles is the first step in that process.”
“The incidents of people losing keys, smartphones and laptops, and even personal and professional data security breaches, could be dramatically reduced in the future with the use of Bluetooth low energy-based proximity sensing,” comments Geir Langeland, Nordic Semiconductor’s Director of Sales & Marketing. “And I think most people and companies will welcome a simple solution based on proximity that helps protect and safeguard their valuable portable electronics and sensitive, personal data.”
