Single Mode Bluetooth LE Stack

Bluetooth Low Energy is a wireless Personal Area Network (PAN) technology designed and marketed by the Bluetooth Special Interest Group (SIG) aimed at applications in the healthcare, fitness, security, and home entertainment industries where low power wireless transmission with long battery life are required.

GlobalEdge’s Bluetooth Low Energy Single Mode Host Stack is a small footprint software stack that is easily portable to a wide range of embedded devices. This stack is compliant to Bluetooth Specification version 4.0 adopted by Bluetooth SIG.

Key Features include:

  • Supports Bluetooth Core 4.0 specification
  • Supports Central, Peripheral, Observer and Broadcaster roles
  • Supports only Piconet scenarios, ie. device can be in any one of the above mentioned devices roles at a given point of time
  • The Central Role supports connecting to multiple peripheral devices
  • Compile time configuration of roles and optional features to meet low foot print requirements
  • Platform Abstraction Layer to keep the stack implementation platform independent with respect to both interfaces and libraries
  • Provides flexibility for the Platform Abstraction Layer to decide the method in which core stack functionalities can be executed. For instance, the stack can be executed in the context of a thread, a timer/interrupt or in the context of main loop
  • HCI Transport Layer Abstraction to support adding different physical transport interfaces like UART, SPI, USB, etc.
  • Debug mode provided to ease porting and integration
  • Btsnoop packet capture format supported


Given below are some of the application areas that can be addressed with GlobalEdge BLE Stack:

  • Health Care Devices
  • Sports and Fitness Devices
  • Internet Connectivity
  • IOT devices
  • Beacon Emitters
  • Sensors

IoT Gateway

With the proliferation of cloud computing platforms, wireless communications, and low power semiconductor devices along with low cost sensor technology, it is now possible to capture data at very high rates and accuracy and send this data via various networks to a central cloud computing system for storage, processing and analytics. This information, garnered from large amounts of data, provides value addition to people and organizations alike.

The areas of IoT that would positively impact personal life include “Connected Home” and “Connected People” technologies where systems are used to monitor homes and learn about the habits of people living within them. Based on learnt habits, the system can then predict a person’s behavior, adjust the environment accordingly, and provide event information to other relevant systems. An example of such a system being sold today is the Nest Learning Thermostat that is part of the Wink Home Automation system.

While IoT has vast applications in the industry, one of its foremost applications is in improving safety and efficiency. By saving lives and reducing costs, this technology literally pays for itself over the course of its deployment.

Communication plays a key role in collecting and conveying data between IoT nodes and the servers in the cloud. Various methods of communication are used both at the physical layer and at the protocol layer.



One of the key components of an IoT communication system is a gateway device that transcodes and forwards data from edge-nodes to servers on the cloud. The gateway could communicate with edge-nodes over one or more wired or wireless networks. An Intelligent IoT gateway will provide additional local services to devices that are connected to it. Services like device discovery, device management, security, clustering and reliability when provided by the gateway can address some of the challenges faced by large scale IoT deployments.

When deploying IoT infrastructure that uses multiple wired and wireless communication protocols and is sourced from multiple vendors, using an Intelligent IoT Gateway could considerably ease the pain, both in terms of setup time and management.

At GlobalEdge, we have been working on developing Intelligent IoT Gateways that provide the benefits discussed in this paper. As part of our Automotive and Industrial Automation practices, these gateway devices also support networks specific to these industries like CAN, Fieldbus, Profibus, Modbus, etc., thus, helping to bring the benefit of IoT into these industries.

Sensor Integration & Testing

The Internet of Things (IoT) is an important development in today’s world. It enables sensors or embedded devices to be interconnected over the Internet. IoT 2.0 will be presented by the enormous quantity of heterogeneous and networked embedded devices that generate intensively “Big data”. The massive amounts of data being exchanged today, and at the current scale, makes it extremely challenging to compute and analyze. As a result, valuable information gets hidden. The IoT depends on collecting vast amounts of data from various sensors that may be deployed across regions.

At GlobalEdge, we focus on:

  • Integrating these sensors into the smallest semiconductor devices running with or without an OS.
  • Developing algorithms to condition the incoming data for smarter analysis.
  • Testing services for various sensors.

Our work in this area is differentiated by a few factors that include:

  • Working on IoT before the proliferation of the word
  • Our experience of about a decade of experience in this area which makes one of the pioneers of the concept
