AnyNet 2G Click

AnyNet 2G Click is a cellular to AWS gateway device, which provides developers with the complete solution for various IoT applications, by using the AWS IoT and Cloud Storage services for the data storage, analyzing and processing.

This click board™ provides an easy and secure connection with the AWS over the air (OTA), by utilizing the equipped Quectel M95 module and Eseye ES4623 embedded SIM card, that can work with more than 235 cellular operators from all over the world. AnyNet 2G click can be used as an AWS IoT button with almost no configuration.

AnyNet 2G click comes supplied with the start-up package - free activation through the AWS, unique ID number of the embedded SIM card and six-month cellular connectivity services of up to 5000 messages to the AWS cloud. With the AnyNet 2G click, users get the unique level of integration with the AWS IoT services.

Note: Before the purchase of AnyNet 2G click, please contact Eseye and check for the coverage and support of embedded SIM cards from your local provider. Opening an AWS account and subscribing to Eseye marketplace is mandatory to work with this click board.

The antenna is sold separately.

How does the click work?

The cellular connection is established through the Quectel M95 2G module (also found on the GSM2 click) and the embedded ES4623 SIM card by Eseye company, used to enable communication and secure connection with the AWS IoT platform. The additional onboard Microchip MCU contains the firmware used to interface the GSM/GPRS module to UART, providing users with easy to use end-point AT commands.

AnyNet 2G click requires both 3.3V and 5V power supply pins from the mikroBUS™ to operate. The 5V rail is used to power up the Quectel M95 module itself through the LVD regulator, while the 3.3V rail is used for powering up the rest of the circuitry.

There are four LEDs used to display the connection status. Before the connection and communication with the AWS are possible, the setup procedure must be followed. For detailed step by step information, refer to the AnyNet 2G click user manual. The manual can be also found in the Downloads.

As already mentioned, onboard 2G module exposes a 9600 baud UART interface, providing users with easy to use AT commands. The user's data is publised to AWS IoT topics. To initiate the communication, a simple AT command string is used to open a topic for publishing user data. An Unsolicited Response Code from the module indicates that the data has been received from a topic to which the module has been requested to subscribe. All the information about how to use AT commands can be found in the AT commands reference.

IoT Button

The Click board™ has the IoT Button feature - a pin routed to the INT pin of the mikroBUS™ Setting this pin to a HIGH logic level is considered as IoT Button press. AWS IoT gateway recognizes three types of messages: short press, long press, and double-click.

The AWS IoT Button pin is based on the Amazon Dash Button hardware. The functionality of this pin is designed for developers to get started with AWS IoT, AWS Lambda, Amazon DynamoDB, Amazon SNS, and many other Amazon Web Services.

IoT Button pin can be coded in cloud service to perform various tasks, such as remote control for Netflix, a switch for Philips Hue light bulb, a check-in/check-out device for Airbnb guests and so on. It can also be integrated with the third-party APIs like Twitter, Facebook, Twilio, Slack or even custom applications.

Firmware updates for the 2G module can be provided over the air. The updates may include additional functionality and improved stability. For any additional technical questions regarding the firmware on this module, contact Eseye technical support.

The AnyNet 2G click features

• Connects development projects globally through 235+ cellular networks across 75+ countries and securely sends data to the AWS account.
• Supplied with a start-up package, including FREE Activation through AWS and a six-month cellular connectivity service of up to 5,000 messages onto the AWS Cloud.
• Provides security features for developers to remotely and securely activate, authenticate and certify the prototype device Over-the-Air directly from the AWS Cloud.
• Instantly meets Cloud security rules and gives immediate scalability as projects grow.

Onboard settings and indicators

Software support

We provide a library for the AnyNet_2G Click on our LibStock page, as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Library Description

The library is composed of driver and API layers both available from user space. Lower driver layer carries generic AT command parser, API layer carries simplified user-friendly function calls.

Key functions

api_anynet2g_queryICCID- Provides ICC ID necessary for registration

api_anynet2g_checkStateAWS- Returns current state of the module

api_anynet2g_openTopicAWS- Opens Topic

Examples descriptions

The example shows how to properly initialize module and use API function calls. All information from the module is logged using UART so two UART modules are necessary for the example. In case that your system has only one UART module, Software UART is also usable for data logging. Also, it is necessary to have an account on Amazon for successful testing.
 

void applicationTask()
{ 
// MODULE INIT
    anynet2g_cmdSingle( "AT" );
    api_anynet2g_firmwareID();
    api_anynet2g_queryICCID();

    api_anynet2g_checkStateAWS( _ANYNET2G_GET );

// OPEN TOPIC 0 AND PUBLISH
    api_anynet2g_openTopicAWS( _ANYNET2G_SET, "0", "MY_TOPIC" );
    api_anynet2g_publishTopicAWS( _ANYNET2G_SET, "0", "MIKROE", "" );
}

In addition to API calls, example carries additional functions for GPIO pin control provided during the driver initialization.

Keep in mind that AnyNet 2G click currently doesn't support Hardware Flow control so implementation of UART interrupt is a must, also timer interrupt is needed.

The full application code, and ready to use projects can be found on our LibStock page.

Other mikroE Libraries used in the example:

• UART
• Conversions
• C_String

Additional notes and information

Depending on the development board you are using, you may need USB UART click, USB UART 2 click or RS232 click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all Mikroelektronika compilers, or any other terminal application of your choice, can be used to read the message.
