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.
