5G NB IoT Click

How does it work?

The Cinterion® ENS22 IoT wireless module marries future 5G connectivity with expanded coverage and enhanced security features to connect and protect industrial IoT solutions. Delivering data speeds up to 27 Kbit/s downlink and 63 Kbit/s uplink, the ENS22 IoT module is ideal for long life data-only solutions such as utility meters and smart city solutions.

5G NB IoT Click features an integrated NB-IoT transceiver, multi-band mobile cellular devices. The module can operate over 698-960 MHz and 1695-2180MHz with a 200 kHz system bandwidth. It is designed to communicate with mobile network operator (MNO) infrastructure equipment using the 3GPP NB-IoT radio protocol.

The Cinterion ENS22 IoT module platform offers a suite of NB-IoT connectivity solutions optimized specifically for IoT applications and prepared to support release 14 without the need to migrate to a new chipset. It delivers Five Band LTE (3, 5, 8, 20, 28) connectivity with deep indoor coverage and extended range in rural areas. The module offers a built-in IP stack which supports a range of internet services protected by an enhanced security concept.

Incremental Firmware Over The Air (FOTA) updates allow revision of only the portion of code that needs updating, saving power and bandwidth to extend the life span of IoT solutions. The module’s simplified power supply design and advanced management system extends battery lifetime and improves TCO.

This Click board™ is equipped with the USB type C connector. It allows the module to be powered and configured by a personal computer. The FT230X IC requires drivers in order to work. FTDI offers drivers for all major OSes on their official driver download web page. Also, Windows OS drivers are included in the download section, below.

5G NB IoT Click have fully-integrated Li-Ion or Li-Polymer battery charger witch in combination with module up to 10 ~ 15 years of battery life allow user using it completely standalone and battery powered ony.

J1 jumper can be used for power consumption monitoring.

Software Support

We provide a library for the 5G NB IoT 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

Library provides control over on pin and ability to send commands through UART module.

Key functions:

• void c5gnbiot_send_cmd ( uint8_t *cmd ) – Function for sending commands to device
• void c5gnbiot_set_on ( uint8_t state ) – Generic function for setting on pin status

Examples description

The application is composed of three sections :

• System Initialization – Initialization of UART MODULE and additional pins
• Application Initialization – Turns on device and sends initial commands
• Application Task – Checks some device parameters by sending AT commands

void application_task ( )
{
    c5gnbiot_send_cmd( &AT_CGATT[0] );
    Delay_ms( 5000 );
    c5gnbiot_send_cmd( &AT_CEREG[0] );
    Delay_ms( 5000 );
}

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

Other mikroE Libraries used in the example:

• UART

Additional notes and informations

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.

mikroSDK

This Click board™ is supported with mikroSDK – MikroElektronika Software Development Kit. To ensure proper operation of mikroSDK compliant Click board™ demo applications, mikroSDK should be downloaded from the LibStock and installed for the compiler you are using.
