How Does The Go to Cloud (G2C) Click board™  Work?

The Go to Cloud (G2C) Click board™ allows connection to the feature-rich Click Cloud platform, over the WiFi network. Go to Cloud (G2C) click is envisioned so that users can easily add cloud connectivity and develop their own cloud-based applications, using only a set of simple AT commands, without having to delve into the complexity of web, hardware, and communications related development. Thanks to this simplified approach, everyone can benefit using the Click Cloud solution with Go to Cloud (G2C) click, since this Click board™ has all the necessary protocol and communication settings already implemented within its firmware. This saves a lot of time that would be otherwise wasted on the firmware development, and to adapting it to work with some third-party solution. Not to mention that such an effort would also require embedded and web programming proficiency, along with several other engineering skills. G2C click, on the other hand, works in unity with Click Cloud solution, right out of the box.

Go to Cloud (G2C) click performs several tasks on its side, which are required to connect to the Click Cloud platform. To establish the connection, an access to a WiFi network with Internet connectivity is required. For a reliable WiFi network connection, the Click board™ utilizes the ESP WROOM-02 WiFi module, a well-established integrated WiFi solution.

The Click board™ uses a powerful MCU to manage the connection parameters, initialize the ESP-WROOM-02 WiFi module, and establish the connection with the Click Cloud platform. This allows to set up the connection in just a few simple steps, issuing a set of short AT commands, such as the SSID, password, device_ID, and so on. The complete documentation with in-depth explanation of each AT command and its response can be found in the AT Command Manual.

Besides the AT commands that are used to set up basic connection parameters, there are also AT commands that allow storing of the connection parameters, including the connection password, network SSID, device_ID, and other relevant connection data. These parameters can be stored in the non-volatile memory of the Go to Cloud (G2C) click. It is possible to restore them by a single macro command, resulting in a very simplified connection procedure.

The functionality of the Go to Cloud (G2C) click will be constantly improved in the future. Therefore, Go to Cloud (G2C) click supports an upgrade of its firmware over the onboard USB connector. The firmware update process is very simple, using the familiar "HID Bootloader" software tool from MikroElektronika.

Go to Cloud (G2C) click is equipped with four LED indicators. They are used to indicate the presence of a power supply, the WiFi network connection, the USB connection, and the connection with the Click Cloud solution. These LEDs provide visual feedback about the status of the Go to Cloud (G2C) click. This Click board™ requires both 3.3V and 5V power rails for proper operation.

Click Cloud Solution

Click Cloud solution is very simple to use, and it relies on a very comprehensive and intuitive web-based Graphical User Interface (WEB GUI). It allows the rapid development of cloud-based applications, offering a set of well-documented functionalities, specially tailored to offer the best experience when used with the Click board™ line of products. However, It can be used with other MikroElektronika products, as well.

Click Cloud hosted by MikroElektronika provides a clean, intuitive, and logical concept, abstracting the Click board™ as a "device" with its "device manifest" that contains a set of pre-configured or custom-created sensors, actuators, and other devices, typically found on various Click boards™. This concept allows very simplified management with nice and clean data representation. An interactive online help within the WEB GUI offers a detailed explanation of each feature of the Click Cloud solution. Besides using the WEB GUI, there is also the possibility to access the Click Cloud over mobile apps, based on IOS and Android OS platforms.

You can discover more about the features offered by Click Cloud solution, at the official Click Cloud page.
