The LTE Cat.1-EU Click Board™ (For the UK and Europe) is a Click Board™ based on Thales Cinterion® ELS61 wireless module that delivers highly efficient Cat 1 LTE connectivity for M2M IoT solutions offering seamless fallback to 2G and 3G networks. The best-in-class solution enables M2M optimized speeds of 10Mbit/s download and 5Mbit/s uplink, making it ideal for the vast number of M2M and industrial IoT applications that are not dependent on speed but that require the longevity of LTE networks while still providing 3G and 2G connectivity to ensure total population and geographic coverage as LTE rolls out.
The LTE Cat.1-EU Click Board™ is supported by a mikroSDK compliant library, which includes functions that simplify software development. This Click Board™ comes as a thoroughly tested product, ready to be used on a system equipped with the mikroBUS™ socket.
NOTE: It is necessary to emphasise that Voice over LTE feature (VoLTE) is supported only on ELS61-USA (AT&T, VoLTE, and CSFB) and ELS61-E (CSFB) wireless modules. Special note for the 4G network: Before buying this product, be sure to check if the modules' LTE bands match the 4G capabilities in your country.
How Does The LTE Cat.1-EU Click Board™ Work?
The LTE Cat.1-EU Click Board™ is equipped with the ELS61 wireless module from Thales. The main difference between these two modules are the supported frequency bands, which comply with each region's regulations. A complete list of supported bands for each module and other relevant info about the module itself can be found in the ELS61 series modem datasheet.
The ELS61-EU module featured on the LTE Cat.1-EU Click Board™ comes with a Java® embedded virtual machine leveraging a robust ARM11 architecture that allows device manufacturers to utilize the massive to reduce complexity and speed application integration. The latest Java ME 3.2 client runtime platform reduces total cost of ownership (TCO) and time to market by sharing internal resources such as memory, a large existing codebase, and proven software building blocks. The module uses Multi MIDlet Java execution to host and run multiple applications and protocols simultaneously.
The UART bus of the ELS61 series module is connected to one side of the level shifter, while the other side (shifted) is connected to the respective mikroBUS™ UART pins. However, the ELS61 series module is designed as the traditional DCE device (Data Communication Equipment) offering the full UART pin count, including the hardware flow control pins (CTS, RTS). These pins are routed to the mikroBUS™ CS (CTS) and the INT pin (RTS) and can be used in the MCU software if the hardware flow control is needed.
An extended security concept with the latest TLS/SSL engine provides secure and reliable TCP/IP connectivity. Its sophisticated sandbox modeling and layered architectures simplify device management and allow simultaneous progress of network operator approvals and application code development for a shorter time to market. The LTE Cat.1 module delivers long product lifespans up to seven years, efficient bandwidth and power utilization plus a feature set that meets the rigorous requirements of M2M IoT solutions including extended operating temperatures from -40°C to 85°C.
The LTE Cat.1-EU Click Board™ ensures easy integration and a fast time to market for innovative solutions, and it also provides a dependable connectivity platform with the support needed for a fast time to market and a value you can trust.
Given these features' possibilities, the LTE Cat.1-EU Click Board™ can be used for various applications such as metering, tracking and tracing, remote surveillance, connected signs, fleet management and mHealth.

NOTE: Pins for SPI and I2C are not connected by default on mikroBUS™ since the module is always acting as master which is not allowed for Click board™, but can be enabled by adding 0 ohm resistors to jumpers from J1 to J6 on the back side.
Software Support
We provide a library for the LTE Cat1 Click on our LibStock page and a demo application (example), developed using Gemalto a Thales company compiles. The demo can run on all the main MikroElektronika development boards.
Library Description
The library covers all the functions to control LTE Cat. 1 Click board™. The library carries generic command parser adopted for AT command based modules.
Key Functions
void ltecat1_cmd_single ( uint8_t *p_cmd )- Sends provided command to the module function.uint16_t ltecat1_set_handler( uint8_t *p_cmd, uint32_t timeout, ltecat1_handler_t p_handler )- Handler assignation to the provied command function.void ltecat1_module_power ( uint8_t power_state )- Enables or disables module power function.
Example Description
The application is composed of three sections :
- System Initialization - Initializes all necessary GPIO pins, UART used for the communcation with GSM module and UART used for infromation logging
- Application Initialization - Initializes driver, power on module and sends few commands for the default module configuration.
- Application Task - running in parallel core state machine and checks for call flag. If call detected parser will hang up call.
void application_task ( )
{
char rsp_com[ 50 ] = {0};
// GSM
// CORE STATE MACHINE
ltecat1_process( );
if (0 != call_flag)
{
ltecat1_cmd_single( <ECAT1_ATH[ 0 ] );
Delay_ms( 3000 );
call_flag = 0;
}
}
void ltecat1_default_handler( uint8_t *rsp, uint8_t *ev_args )- Default handler.
The full application code, and ready to use projects can be found on our LibStock page.
Other mikroE Libraries used in the example:
- UART
- Conversion
- String
Additional Notes and Information
Depending on the development board you are using, you may need USB UART Click Board™, USB UART 2 Click Board™ or RS232 Click Board™ 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
The LTE Cat.1-EU 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.
