LSR has just released source code for a new cloud-connected demo for its Sterling-LWB for WICED reference platform! With this release, customers can test out how to connect the Sterling-LWB for WICED to a TiWiConnect cloud server. Section five of the user guide, Sterling-LWB Cloud Sensor Demo Featuring TiWiConnect, has been updated with the latest demo. This section demonstrates the use case of a cloud-connected sensor.

 

LSR, now a Laird business, developed a sample project that can be used with the Sterling-LWB for WICED expansion carrier board for real-time reporting of accelerometer, gyro, and magnetometer sensor data from an attached STM32F411 Discovery Board to a web and mobile application. The sample code for use with WICED Studio can be downloaded from the Sterling-LWB “Software Downloads” tab (930-0079) of the LSR website. The project source code provides developers an overview of the steps involved when developing a typical BLE+Wi-Fi enabled sensor including:

  • Defining and implementing custom BLE profiles for communicating with a mobile app
    • Simple Sensor Profile
    • Wi-Fi Configuration Profile
    • LIFT Configuration Profile (for provisioning cloud API access)
  • Steps required to assign Wi-Fi credentials to the device over a BLE connection
  • Steps required to assign cloud authentication credentials to the device over a BLE connection
  • Basic driver for interfacing with sensors over I2C and SPI bus and LED control
  • Steps required to post sensor data to a cloud API via HTTP (HTTPS option included)
  • Steps required to receive remote cloud API commands to perform an action (e.g. toggle LEDs)
  • Persistent storage of credentials to Device Configuration Table (DCT) in Flash

Last week LSR, a Laird Business, attended Electronica 2016. In addition to announcing the upcoming 60 Series, we also proudly featured our Cypress based Wi-Fi modules. Just last month we announced two new solutions, the Sterling-LWB5 and Sterling-LWB for WICED. These new solutions, based on Cypress radios, expand LSR's Sterling family of Wi-Fi + Bluetooth multi-standard modules, joining the popular Sterling-LWB 2.4 GHz certified module. Both the Sterling-LWB and Sterling-LWB5 utilize latest-generation silicon technology that Cypress acquired from Broadcom in 2016. The Sterling-LWB5 uses the powerful Cypress BCM43353 chipset to create one of the very first commercially available certified modules that offers IEEE 802.11ac capabilities for ultra-high data rate 5 GHz band Wi-Fi connectivity.

Innovative Alternatives to AT Command Sets

Leveraging the simplicity of TiWiConnect LIFT device-to-cloud software for embedded Wi-Fi® product design

With the current white-hot trends of the Internet of Things (IoT) and Machine-to-Machine (M2M) communications, there is a strong push on product developers to convert their current products into “connected products” by integrating Wi-Fi or another wireless technology. While the technology and capabilities of Wi-Fi modules have progressed significantly in recent years, there remains a common perception that an “AT-like” ASCII command set is the best way for a host to control a Wi-Fi module over a serial interface.

 

The goal of this white paper is to walk through the benefits and inherent limitations of traditional ASCII-based command sets for integrating Wi-Fi for cloud-based systems, and detailing how new software approaches can provide significant advantages in development time and efforts for those engineering teams that lack deep experience in Wi-Fi development.

"Don't I need LINUX to add Wi-Fi to my embedded design?"

Leveraging a fully integrated WLAN module for embedded Wi-Fi product design


Embedded system designers face many challenges when selecting the right components to meet functional, budgetary, and regulatory requirements, especially when it involves wireless technologies. Until recently, adding Wi-Fi meant learning and implementing complex software subsystems just to provide a seemingly simple wireless network connection. This typically would involve a deep dive into embedded operating systems such as Linux, complex development environments to compile Wi-Fi drivers, rebuilding kernels, and countless hours spent wrestling with tools unrelated to your actual product functionality.

 

With the latest System-on-Chip (SoC) technologies, the complexity of Wi-Fi has been pushed into the wireless module, allowing developers to focus on their application data instead of designing a platform to support Wi-Fi.

"Is there an App for that?"

Leveraging the Cloud to add powerful Mobile App connectivity to your Products

 

Whether driven by customer feedback, competitive pressures, or opportunities to streamline business processes and minimize costs, more and more product developers are being tasked with adding a smartphone connection to enhance their product offering.  In reality, it’s a version of short-hand to speak in terms of simply “adding an App” to a product.   In most cases, the product requirements are really asking for the product to become part of a cloud-connectivity system, which leverages cloud-servers and the internet connectivity of phones, tablets, laptops, and of course, your product to provide remote monitoring and control capabilities.

 

The goal of this white paper is to walk through the elements of building a cloud-connectivity system to support remote App connectivity for your product, so you can have a robust and exciting solution to share when your customer, sales professional, or your CEO asks, “Is there an App for that?”  As the elements of a cloud solution are defined, key design considerations that a product development team will need to address are also highlighted.  Lastly, the white paper will provide a simple, intuitive framework for defining the capabilities you will need your design to include.
