Neu: LinTech Light Control mit Bluetooth Smart® und Mesh-Netzwerk-Technologie

Flexible Lichtsteuerung für tausende Geräte mit LinTechs Bluetooth®-Low-Energy-Modulen Berlin, 11. März 2016. Mit LinTech Light Control über Bluetooth® Low Energy (BLE) bietet der Berliner Bluetooth®-Spezialist LinTech Herstellern eine einfache, zeit- und kostensparende Möglichkeit, drahtlos vernetzte Lichtlösungen mit Tausenden von Lampen oder LEDs zu realisieren. Das LinTech-Light-Control-System basiert auf LinTechs bewährten BLE-Modulen BTM-800 und BTM-840 mit Protokoll- und Applikationssoftware inkl. Demo-App und unterstützt die Mesh-Network-Technologie. LinTech Light Control unterstützt zahlreiche Anwendungen, darunter LED-Treiber (1-4 Kanäle), Lichtsteuerungen, Leuchten, ein- und mehrfarbige LED-Lampen sowie Lichtwerbung. Die verwendeten Bluetooth®-Smart-Module BTM-800 und BTM-840 von LinTech zeichnen sich durch einfachste Integration, transparente Datenübertragung, extrem geringe Abmessungen (BTM-840: 11 x 11 mm, BTM-800: 20 x 12 mm) und einen sehr niedrigen Energieverbrauch aus. Sie funken mit einer Reichweite von ca. 60m und unterstützen auch sogenannte Mesh-Netzwerke, können also Informationen untereinander weiterleiten. Auf diese Art und Weise kann eine Vielzahl von Teilnehmern ohne zusätzliche Verteilerknoten erreicht werden. Bei Lichtsteuerungsanwendungen erlaubt diese Technologie den Aufbau von großen Netzwerken mit Tausenden von LEDs oder Lampen, die zentral oder in einzelnen Gruppen gesteuert werden können. LinTech Light Control nutzt dafür das CSRmesh®-Protokoll des Chipsatzherstellers CSR (jetzt Qualcomm), welches die kabellose Steuerung des Mesh-Netzwerkes über ein bluetoothfähiges Gerät (BLE) ermöglicht. Dafür wird kein externes Gateway benötigt. LinTech Light Control kann im Mesh-Netzwerk bis zu 65.535 Geräte adressieren. Außerdem hat LinTech eine Demo-App für den Aufbau und Konfiguration des Mesh-Netzwerkes und die Lichtsteuerung entwickelt. Die App ist für iOS und Android verfügbar. posted by HR-Gateway

Bluetooth gets physical with new fitness certifications

#SuryaRay #Surya The Blutooth Special Internet Group has seen the coming quantified-self revolution and has released two new certifications aimed at devices that track running and cycling. The group, which certifies Bluetooth accessories such as your headset or the radio that connects your wireless keyboard to your computer, two years ago began addressing the need for a lower-power version of the standard to connect fitness monitors such as a Nike+ FuelBand. The two new standards are approved for sensors that will measure elements such as running cadence, stride length, total distance, or cycling speed, distance and pedal cadence to Bluetooth-enabled devices like smartphones, sports watches and cycling computers. Presumably this will boost accuracy in fitness monitoring devices. For example, some devices have a hard time adjusting their calories or effort metrics for running because they don’t take into account a longer or shorter running stride when compared to walking. Unfortunately, until the emergence of Bluetooth Low Energy makers of the Fitbit (see disclosure) and even the Nike Run profile had to resort to proprietary connection that had a lower energy profile. The net result is those devices require specialized dongles to connect to a computer as opposed to just automatically interfacing with the Bluetooth chip already on board. Hopefully as Bluetooth Low Energy goes mainstream, and the SIG adds more accurate sensor profiles to the Bluetooth ecosystem, those who still have proprietary standards will be more inclined to switch. After all, having your fitness devices on a common standard is a win for consumers. _Disclosure: Fitbit is backed by True Ventures, a venture capital firm that is an investor in the parent company of this blog, Giga Omni Media.
