Das LTE Cat.1-US Click Board™ basiert auf dem drahtlosen Modul Thales Cinterion® ELS61, das hocheffiziente Cat 1 LTE-Konnektivität für M2M-IoT-Lösungen bietet und einen nahtlosen Fallback auf 2G- und 3G-Netzwerke ermöglicht. Die branchenführende Lösung ermöglicht M2M-optimierte Geschwindigkeiten von 10 Mbit/s Download und 5 Mbit/s Uplink und ist damit ideal für die große Zahl von M2M- und industriellen IoT-Anwendungen, die nicht von der Geschwindigkeit abhängig sind, aber die Langlebigkeit von LTE-Netzwerken erfordern, während sie gleichzeitig 3G- und 2G-Konnektivität bietet, um eine vollständige Bevölkerungs- und geografische Abdeckung bei der Einführung von LTE sicherzustellen.
How Does The LTE Cat.1-US Click Board™ Work?
The LTE Cat.1-US Click Board™ is equipped with the ELS61 wireless module from Thales. There are two click boards to cover two different regions: LTE Cat.1-EU click for the Europe region, which features the ELS61-E module, and the LTE Cat.1-US click for the North American region, which features ELS61-US module. The main difference between these two modules are the supported frequency bands, compliant with the regulations for each region. A complete list of supported bands for each module, along with other relevant info about the module itself, can be found in the ELS61 series modem datasheet.

The Cinterion ELS61 module that is featured on LTE Cat.1-US click comes with a Java® embedded virtual machine leveraging a powerful ARM11 architecture which 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 code base and proven software building blocks. The module uses Multi MIDlet Java execution to simultaneously host and run multiple applications and protocols.
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 (RTS) and the INT pin (CTS) 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. Cinterion LTE Cat.1 modules deliver 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-US 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 all the possibilities these features offer, the LTE Cat.1-US 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 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 Cat.1-US Click Board™k 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 covers all the necessary functions to the LTE Cat.1-US Click Board™. 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 command 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 a 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
The LTE Cat.1-US 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.
