硬件概览
它是如何工作的？
4G LTE 2 Click基于u-blox的LARA-R6001D，是一款支持LTE Cat 1 FDD和LTE Cat 1 TDD无线接入技术（18个LTE频段）、同时支持3G UMTS/HSPA和2G GSM/GPRS/EGPRS回退的多频段和多模式模块，提供了完美的全球连接解决方案。这个Click板™代表了一个仅支持数据的解决方案，具有全球覆盖和所有相关移动网络运营商认证，除了不支持语音/音频应用之外，提供了极大的灵活性。多接口和功能使LARA-R6001D非常适合需要中等数据速度、出色覆盖范围和流媒体数据的各种应用，如资产跟踪、远程监控、销售终端等。该模块需要3.8V的电源供应。因此，Click板™集成了德州仪器的TPS7A7002集成降压（DC-DC）转换器，提供稳定的3.8V电源，能够在输入电流峰值出现时（通常在设备启动时）减少电
压下降。模块点火（上电）引脚，标记为PWR并路由到mikroBUS™插座上的RST引脚，使电源可以开关。LARA-R6001D使用UART接口与MCU通信，通常使用UART RX和TX引脚，硬件流控引脚UART CTS、RTS、RI（发送清除、准备发送和响铃指示器）。它默认配置为115200 bps，通过u-blox提供的AT命令与主机MCU传输和交换数据。除了UART接口，LARA-R6001D还提供了使用I2C接口作为I2C主机的可能性，可以通过I2C总线规范与I2C本地设备通信。这个Click板™还配备了一个USB Type-C连接器，仅用于诊断目的，其中模块充当USB设备，可以连接到任何具有兼容驱动程序的USB主机。在使用的引脚中，这个Click板™还具有两个额外的LED指示灯：黄色LED标记为STATUS，都路由到mikroBUS™ AN引
脚（STS）。LTE蜂窝网络使用空间复用天线技术，允许使用多个天线以获得更好的接收。因此，除了主天线和用于视觉上指示网络连接状态的LED，以及红色LED标记为TX用于指示模块的传输状态之外，这个Click板™还使用了次要多样性RX天线，从而实现更好的信号接收。除了SMA连接器，4G LTE 2 Click还配有一个Nano-SIM卡槽，提供多种连接和接口选项，以及几个标记为TP1到TP3的测试点，可以轻松重新启动和测试模块。这个Click板™可以通过VCC SEL跳线选择3.3V或5V逻辑电压级别。这样，既可以使用3.3V逻辑电平的MCU，也可以使用5V逻辑电平的MCU正确使用通信线路。然而，这个Click板™配备了一个包含易于使用的函数和示例代码的库，可用作进一步开发的参考。

应用程序输出
1. 应用程序输出 - 在调试模式下，“应用程序输出”窗口支持实时数据监控，直接提供执行结果的可视化。请按照提供的教程正确配置环境，以确保数据正确显示。
2. UART 终端 - 使用UART Terminal通过USB to UART converter监视数据传输，实现Click board™与开发系统之间的直接通信。请根据项目需求配置波特率和其他串行设置，以确保正常运行。有关分步设置说明，请参考提供的教程。
3. Plot 输出 - Plot功能提供了一种强大的方式来可视化实时传感器数据，使趋势分析、调试和多个数据点的对比变得更加直观。要正确设置，请按照提供的教程，其中包含使用Plot功能显示Click board™读数的分步示例。在代码中使用Plot功能时，请使用以下函数：plot(insert_graph_name, variable_name);。这是一个通用格式，用户需要将“insert_graph_name”替换为实际图表名称，并将“variable_name”替换为要显示的参数。

* @file main.c
* @brief 4G LTE 2 Data Click Example.
*
* # Description
* Application example shows device capability of connecting to the network and
* sending SMS or TCP/UDP messages using standard "AT" commands.
*
* The demo application is composed of two sections :
*
* ## Application Init
* Initializes the driver, restarts the module and tests the communication.
*
* ## Application Task
* Application task is split in few stages:
* - C4GLTE2DATA_CONFIGURE_FOR_NETWORK:
* Sets configuration to device to be able to connect to the network.
*
* - C4GLTE2DATA_WAIT_FOR_CONNECTION:
* Waits for the network registration indicated via CREG URC event and then checks the connection status.
*
* - C4GLTE2DATA_CONFIGURE_FOR_EXAMPLE:
* Sets the device configuration for sending SMS or TCP/UDP messages depending on the selected demo example.
*
* - C4GLTE2DATA_EXAMPLE:
* Depending on the selected demo example, it sends an SMS message (in PDU or TXT mode) or TCP/UDP message.
*
* By default, the TCP/UDP example is selected.
*
* ## Additional Function
* - static void c4glte2data_clear_app_buf ( void )
* - static err_t c4glte2data_process ( void )
* - static void c4glte2data_error_check( err_t error_flag )
* - static void c4glte2data_log_app_buf ( void )
* - static err_t c4glte2data_rsp_check ( void )
* - static err_t c4glte2data_configure_for_network( void )
* - static err_t c4glte2data_check_connection( void )
* - static err_t c4glte2data_configure_for_example( void )
* - static err_t c4glte2data_example( void )
*
* @note
* In order for the examples to work, user needs to set the APN and SMSC (SMS PDU mode only)
* of entered SIM card as well as the phone number (SMS mode only) to which he wants to send an SMS.
* Enter valid values for the following macros: SIM_APN, SIM_SMSC and PHONE_NUMBER_TO_MESSAGE.
* Example:
SIM_APN "internet"
SIM_SMSC "+381610401"
PHONE_NUMBER_TO_MESSAGE "+381659999999"
