Hardware Overview
How does it work?
4G LTE&GNSS Click is based on the LENA-R8 (LENA-R8001M10-00C), a multi-mode LTE Cat 1bis module with wide network support from u-blox. This cellular module has 14 LTE bands and four GSM/GPRS bands, delivering universal network connectivity and comprehensive global coverage. Its integrated u-blox GNSS functionality positions it as a premier choice for global tracking and telematics applications, where precision and reliability are paramount. The LENA-R8's capability to support connectivity and location services natively simplifies the deployment of devices in cloud-based ecosystems, offering streamlined solutions for Connectivity as a Service (CaaS) and Location as a Service (LaaS). This makes it an invaluable component for developers seeking to create smaller, more efficient solutions without compromising GNSS performance or global accessibility. Beyond its global LTE Cat 1bis connectivity, the LENA-R8 excels in facilitating a wide array of IoT applications, particularly in the tracking and telematics domains. Its compatibility with a broad spectrum of LTE and 2G bands ensures optimal roaming coverage across different geographical regions, enabling the creation of IoT devices that are truly global with a single product SKU. The module's high level of integration includes support for MQTT Anywhere services on the Thingstream platform, enhancing its utility for seamless global roaming. It also boasts concurrent reception capabilities for up to four GNSS (GPS, GLONASS, Galileo, and BeiDou), with GPS and Galileo being the default configuration. This multifunctionality, combined with dedicated interfaces for the cellular modem and GNSS subsystems, allows for independent operation and flexible usage, optimizing performance and power efficiency. The LENA-R8's support for CellLocate, a network-based location service, further underscores its versatility and suitability for a wide range of high-performance, location-dependent applications. The LENA-R8 communicates with the host MCU using the UART interface with commonly
used UART RX and TX pins with the hardware flow control pins UART CTS, RTS, RI (Clear to Send, Ready to Send, and Ring Indicator). It operates at 115200 bps by default configuration to transmit and exchange data with the host MCU. Besides UART pins, this Click board™ also uses an RST pin as an abrupt hardware reset of LENA-R8. This reset is performed without storing the current parameter settings, and a clean network detach. The LENA-R8 also includes a USB High-Speed 2.0 compliant interface with a maximum 480 Mbit/s data rate. The module itself acts as a USB device and can be connected to any compatible USB host. The interface is available for communication with the external host application processor (AT commands, data, FW update by means of FOAT), FW update by means of a dedicated tool, and diagnostics. In addition, on the back side of the board, there is a USB BOOT jumper that allows you to select the Boot mode. By placing it at position 1, the FW update by the dedicated tool over the USB interface is enabled, and at position 0 for boot in normal operating mode. In addition to its integrated Power (PWR) button for manual activation, the LENA-R8 module can be powered through an external PWR pin. Furthermore, the module has two distinct LED indicators to convey critical operational status information visually. The yellow LED, labeled NI, serves as a network status indicator, offering immediate feedback on the module's connectivity status within a network. This is crucial for troubleshooting and confirming successful network integration. Similarly, the red LED, labeled TP, acts as a time pulse indicator, emitting a precise signal to denote time synchronization events. This is especially beneficial for applications requiring high timing accuracy, such as time-sensitive data collection or GPS-based positioning. The board features u.Fl connectors for LTE and GNSS antennas, accommodating accessories like the LTE Flat Rotation Antenna and the GNSS Active External Antenna, in combination with an IPEX-SMA cable
for flexible and efficient connectivity options. This setup ensures optimal signal strength and quality for local and satellite communications. Notably, the GNSS antenna connection includes a power selection feature, allowing users to adjust the antenna's power supply according to specific requirements, enhancing the precision and reliability of satellite navigation. Additionally, the board is equipped with a nano SIM card holder that supports both 1.8V and 3.0V SIM cards, ensuring compatibility with a wide range of cellular networks and allowing users to select the most appropriate service provider for their particular use case. This Click board™ also uses the TPS7A7002, a Low-Dropout Regulator (LDO) from Texas Instruments, to generate the required 3.8V power supply necessary for the module's optimal operation. This power is derived from the 5V mikroBUS™ power rail or a USB connection if available, ensuring versatility in power sourcing. The board has several test points for further diagnostics and operational adjustments. TP1 is dedicated to diagnosing the module's internal conditions, providing a typical output of 1.8V when the cellular component of the module is activated. This allows for real-time monitoring of the module's power state. TP2 presents the same function as the PWR pin, TP3 as Reset, and TP4 as USB Boot. TP5 and TP6 connect the GNSS UART, enabling serial communication between the internal u-blox M10 GNSS chipset and an external host. This feature allows for direct data exchange and configuration between the GNSS module and the host device, enhancing the module's functionality and flexibility in GNSS applications. This Click board™ can operate with either 3.3V or 5V logic voltage levels selected via the VCC SEL jumper. This way, both 3.3V and 5V capable MCUs can use the communication lines properly. Also, this Click board™ comes equipped with a library containing easy-to-use functions and an example code that can be used as a reference for further development.

* @brief 4G LTE GNSS Click Example.
*
* # Description
* Application example shows device capability of connecting to the network and
* sending SMS or TCP/UDP messages, or retrieving data from GNSS using standard "AT" commands.
*
* The demo application is composed of two sections :
*
* ## Application Init
* Initializes the driver, restarts the device, and after that tests the communication by sending "AT" command.
*
* ## Application Task
* Application task is split in few stages:
* - C4GLTEGNSS_CONFIGURE_FOR_NETWORK:
* Sets configuration to device to be able to connect to the network (used only for SMS or TCP/UDP demo examples).
*
* - C4GLTEGNSS_WAIT_FOR_CONNECTION:
* Waits for the network registration indicated via CREG URC event and then checks
* the connection status (used only for SMS or TCP/UDP demo examples).
*
* - C4GLTEGNSS_CONFIGURE_FOR_EXAMPLE:
* Sets the device configuration for sending SMS or TCP/UDP messages or for retrieving data from GNSS
* depending on the selected demo example.
*
* - C4GLTEGNSS_EXAMPLE:
* Depending on the selected demo example, it sends an SMS message (in PDU or TXT mode) or TCP/UDP message or
* waits for the GPS fix to retrieve location info from GNSS.
*
* By default, the TCP/UDP example is selected.
*
* ## Additional Function
* - static void c4gltegnss_clear_app_buf ( void )
