Bluetooth Low Energy (BLE) or Bluetooth Smart is the low energy version of Bluetooth and integrated into the Bluetooth standard v4.0. The presentation briefs about the BLE and its architecture.
Presented at Robert Bosch Centre for Cyber Physical Systems at Indian Institute of Science, Bengaluru
Slides are mainly on the major security flaws that existed in the Bluetooth 4.0/4.1 (released 2010) specifically Bluetooth Low Energy(BLE) (a.k.a Bluetooth Smart) specification. BLE was introduced as part of Bluetooth 4.0 targeting low power devices which is quite different from classic Bluetooth. Later part contains major security enhancements that are introduced in BLE 4.2
A talk I gave to Hackware v0.7, v0.8, Hackers & Painters, NUS Hackers, One Maker Group and iOS Dev Scout to introduce the audience to basic Bluetooth Low Energy concepts followed by code explanations.
Part 1 of my presentation at Hackware v0.7 (Arduino and Android only) can be seen here. https://www.youtube.com/watch?v=pNnwXPatzjc
Part 2 (Raspberry Pi, iOS and BLE Sniffer) can be seen here. https://www.youtube.com/watch?v=UDNkrlfW9Sg

With an installed base approaching 4 million nodes IO-Link is THE protocol for communication down to the sensor and actuator level. This presentation will be covering what a typical IO-Link solution consists of, how it interfaces to the control system and the benefits that can be derived from this increased level of communication with IO-Link devices. These include: easier handling of measurement signals, remote and automatic device parameterisation, smart sensor diagnostic functions, safety over IO-Link whilst also being an enabler for Industrial IoT and Industry 4.0 strategies.

The prime concern of this project is to develop a system that is more friendly for all but especially blind, elderly(senile) people so that they can use it with more ease as it is self-controlled. It will also reduce human efforts to great extent. It is used for maximizing user’s comfort offering an easy way to personalize home.

LST Vocoder Product Synopsis:
The LST Vocoder Module from Linkstar Technologies Ltd is a product inspired from a previous
version of a Vocoder module. Linkstar has successfully designed and developed a newer
generation Vocoder integrating multiple features required in a Communications environment.
The new LST Vocoder series has integral features beyond the realm of any available Vocoder
product. The LST Vocoder is integrated with interface and peripheral needed for a product
manufacturer, without need for additional peripheral circuits. The Vocoder configurations and
functionality are “User Software Configurable”, and also allows user to port “Proprietary
Algorithms” to the Module, through the “Evaluation and Programming Kit”. This reduces
redundant hardware to an end product. The LST Vocoder is manufactured to stringent quality
standards, making it extremely robust and reliable.
