Nordic Semiconductor has launched a Bluetooth 5 ready SoC with features and capabilities that redefine the performance envelope by delivering 4x range and 2x bandwidth for Bluetooth low energy applications. The nRF52840 SoC is especially suited to smart home and advanced wearables applications, including wearables for payments and medical, as well as industrial sensor and other Internet of Things (IoT) devices.It has been designed to support the latest Bluetooth 5 specifications. Bluetooth 5 introduces longer range and throughput improvements that significantly enhance Bluetooth wireless technology’s suitability for smart home, wearables, and IoT applications. Compliance with the specification, coupled with increased maximum output power, enables the nRF52840 SoC to deliver Bluetooth low energy wireless connectivity with up to 4x the range or 2x the raw data bandwidth (2Mbps) compared with the Bluetooth low energy implementation of Bluetooth 4.2.In addition to Bluetooth 5 support, the nRF52840 SoC includes IEEE 802.15.4 capability. 802.15.4 wireless technology forms the basis of smart home technologies such as ZigBee and Thread (with additional upper layers not defined by the standard). IEEE 802.15.4 can also be employed as a Network Adaptation Layer with 6LoWPAN and standard Internet Protocols. The nRF52840 SoC’s support for 802.15.4 significantly extends the product’s capability as an interoperable foundation technology for IoT, smart home, or industrial sensor wireless networks using several different wireless technologies.This new SoC has been built on the mature architecture of Nordic Semiconductor’s existing nRF52 Series of SoCs to support complex Bluetooth low energy and other low-power wireless applications that were previously not possible with a single-chip solution. The uses the proven 64 MHz, 32-bit ARM Cortex M4F processor employed on Nordic’s nRF52832 SoC, plus a CPU with ample generic processing power, Floating Point, and DSP performance, to meet the demands of even the most demanding wireless applications.The nRF52840 SoC’s hardware enhancements compared with Nordic’s existing nRF52832 SoC include a new radio architecture with an on-chip PA boosting output power considerably, and extending the link budget for ‘whole house’ applications; a doubling of Flash memory to 1MB and a quadrupling of RAM memory to 256 kB; support for Bluetooth 5, 802.15.4, ANT, and proprietary 2.4 GHz wireless technologies; a full speed USB 2.0 controller; and a host of new peripherals (many with EasyDMA) including a quad-SPI interface. The nRF52840 can also operate from power supplies above 5V, such as re-chargeable battery power sources.Designed to address the inherent security challenges that are faced in IoT, the nRF52840 SoC incorporates the ARM CryptoCell-310 cryptographic accelerator offering best-in-class security for Cortex-M based SoCs. Extensive crypto ciphers and key generation and storage options are also available.The introduction of the nRF52840 SoC will be accompanied by the release of the S140 SoftDevice, Nordic’s latest addition to its family of RF protocol software ‘stacks’. The S140 SoftDevice is a Bluetooth 5 compliant software stack with support for the long range and high data throughput features of Bluetooth 5.Nordic will release its S140 SoftDevice and associated nRF5 SDK with support for Bluetooth 5 longer range and high throughput modes upon ratification of the Bluetooth 5 standard in early December.Engineering samples and development kits will be available to order from Nordic’s global distribution network from December 6th. Production variants of the nRF52840 will be available Q4 2017.

Akwa United midfielder Kelly Kester has said he and his teammates are optimistic of advancing to the round-robin group stage of the 2018 CAF Confederation Cup when they face Al Hilal in the second leg of their playoff tie.The Sudanese giants defeated the ‘Promise Keepers’ 2-0 in Omdurman in the first leg, just over a week ago, and ahead of the second leg clash in Uyo tomorrow (Wednesday), Kester told www.busybuddiesng.com that Akwa United are capable of cancelling the deficit to progress to the group stage of the competition.“We are going into the game with every belief and confidence that we will win very well and qualify,” the former Enyimba man said. “We are very ready for the game.”Kester also dismissed suggestions that his side’s unimpressive home record in the competition could be their undoing.Abdu Maikaba’s men have won only one of their 3 home matches in the competition, losing twice in the process.“In the past, Akwa United have not won any match on the continent at home but we won this year. Also in the past, Akwa United have not gone beyond the first round of the competition but we did that this year.“So I think this is the season to change everything and gradually we are doing that.“I believe we can do it and go into the group stage (of the CAF Confederation Cup),” he said.The match between Akwa United and Al Hilal of Sudan is slated for 4pm on Wednesday at the Godswill Akpabio International stadium in Uyo.Audio Playerhttps://www.busybuddiesng.com/wp-content/uploads/2018/04/Kelly-Kester-April-17.mp300:0000:0000:00Use Up/Down Arrow keys to increase or decrease volume.RelatedAkwa United Star Kelly Kester Firmly Focused On NPFL TitleAugust 22, 2018In “Nigeria”CAF CL: Lobi Not Under Pressure Ahead of Sundowns Showdown – Kelly Kester (AUDIO)January 10, 2019In “Champions League”NPFL: Kelly Kester “Honoured” To Join ‘Very Ambitious’ Kano Pillars (AUDIO)September 19, 2019In “NPFl”
Robert Voets/Warner Bros. Entertainment Inc. © 2017 WBEI. All rights reserved.(LOS ANGELES) — Actor Bill Paxton died of stroke days after undergoing surgery to fix an aortic aneurysm and repair a heart defect, according to his death certificate.The 61-year-old actor died on February 25, just 11 days after undergoing surgery to repair the aneurysm and replace a valve in his heart.His death certificate also revealed that the longtime actor, star of films like Twister and Aliens, was born with a form of heart disease called bicuspid aortic valve. It is a birth defect characterized by the aortic valve having only two small leaflets that help regulate blood flow in the heart instead of the usual three.The defect is associated with increased risk of aneurysm, stroke or heart failure. It is one of the most common cardiac birth defects and is estimated to be present in two percent of the population, according to the Cleveland Clinic.Paxton’s death certificate does not specify the cause of his fatal stroke or whether it was related to his birth defect.Paxton’s representative did not immediately respond to ABC News’ request for additional comment about the cause of death.In an earlier statement, his family said the actor and Texas native died due to complications from surgery.Copyright © 2017, ABC Radio.
