Le Thingstream Click Board™ est un Click Board™ de passerelle IoT avec le SDK client Thingstream préinstallé. Cela permet à l'appareil de se connecter au réseau mondial MQTT Thingstream et aux outils de connectivité dès sa sortie de la boîte. La connectivité mondiale est obtenue en se connectant au réseau GSM le plus puissant disponible sur plus de 600 réseaux dans le monde. Ce Click Board™ permet d'apporter facilement la connectivité Thingstream aux ordinateurs et aux microcontrôleurs embarqués en utilisant simplement l'interface UART ; celle-ci peut être configurée et gérée à l'aide d'un ensemble minimal de commandes AT bien documentées.
Le Thingstream Click Board™ est pris en charge par une bibliothèque compatible mikroSDK, qui comprend des fonctions qui simplifient le développement logiciel. Ce Click Board™ est un produit entièrement testé, prêt à être utilisé sur un système équipé du socket mikroBUS™.
The Thingstream Click Board™ enables low-cost, low-power IoT connectivity and simple software integration with the Thingstream MQTT broker and cloud-based data management platform. It is designed to be connected to existing production or prototype baseboards with a mikroBUS socket. In addition, This Click board™ also comes with a start-up package comprising free Thingstream account activation, an embedded Thingstream SIM and three months of free global cellular connectivity. The device is activated by a redemption unique to the embedded SIM.
Each Thingstream Click Board™ comes with three months of full access to the Thingstream global MQTT network and connectivity software tools and Data Flow Manager with up to 500 MQTT messages per month from the moment of activation.
How Does The Thingstream Click Board™ Work?
The Thingstream Click Board™ is equipped with the SIM868, an 802.11b/g/n quad-band GPS/GLONASS/GSM location tracking and mobile communication module from SIMCom. This allows the device to connect to the Thingstream global MQTT network over GSM. Thingstream Click enables rapid development of intelligent IoT applications and simplified connectivity with cloud platforms using just a tiny set of AT commands and a flow-chart style application builder (Data Flow Manager), removing the complexities of web, hardware, and communications-related development. This Click board™ is preconfigured with all of the necessary protocols and communications settings to connect with the Thingstream global MQTT network and Data Flow Manager. This is implemented via the Thingstream client SDK, which can be used for the development of the firmware located on the onboard STM32F407 MCU. Results can be achieved quickly without a deep understanding of software engineering and web programming.
To find out more about AT commands and how to Click board™ see the following guides:
- AT Command Set manual
- Quick User Guide
Thingstream Click is equipped with various LED indicators. Separate LEDs are used to indicate the presence of a power supply, the network status and pulse per second indication (1PPS).
This Click board™ also contains a universal RGB LED for other feedback relating to the status of the Thingstream Click. This Click board™ requires 5V power rail for proper operation.
Besides the onboard USB connector, all of the mikroBUS™ pins on this Click Board™ are routed to the appropriate pins of the onboard STM32F407 MCU. That way, it is ensured that users will have plenty of space for future upgrades and development. This enables a broad range of custom applications, including support for I2C and SPI communication interfaces.
All available interfaces can be made available to the mikroBUS header. By default, the board only supports UART communication using AT commands. Other interfaces like SPI, I2C, PWM and Analog can be supported by firmware updates. If you require this functionality, please contact the Thingstream team.
This Click board™ uses 3.3V logic level only. To be able to use it with MCUs that use 5V logic level on their communication lines, a proper level-translation circuit should be used.
THINGSTREAM CONNECTIVITY PLATFORM
The Thingstream connectivity platform provides out-of-the-box, global IoT connectivity. As the only provider of truly global, low-power IoT connectivity, Thingstream's platform enables devices to simply connect to the strongest GSM network available, almost anywhere in the world and communicate using MQTT Messaging. Thingstream provides coverage for over 190 countries across 600+ networks worldwide, providing access to its single largest IoT network.
Thingstream's connectivity platform enables two-way intelligent communication between device and IoT application and with proven scalability, the platform is ideal for delivering mass IoT deployments. It doesn't use TCP-IP and therefore, with no IP (Internet) dependency, things are inherently more secure and connectivity is delivered via a proven high availability, high performance global messaging platform.

Software Support
We provide a library for the Thingstream Click Board™ on our LibStock page and a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.
Library Description
Library provides functions for powering up device, sending commands and controlling devices, and functions for parsing data read from GPS module.
Key Functions
