硬件概览

它是如何工作的?

Wireless SUN Click基于Rohm Semiconductor的BP35C5,这是一款超紧凑的Wi-SUN FAN兼容无线通信模块。BP35C5已通过ARIB和FCC的无线电法律认证,因此可以在920MHz频率下使用,采用二进制GFSK调制方法,在日本和美国使用。它还包括一个Wi-SUN软件堆栈,可以在不同的传输模式(20、10或1mW)下进行高效操作。此外,由于它具有内置的安全功能,并支持模块端的通信加密和安全密钥更新,因此可以在不需要复杂控制的情况下有效地进行安全通信。正如之前提到的,该模块使用Wi-SUN FAN(Field Area Network)网状网络协议,由一个称为边界路由器的父中继器、一个称

为路由器的中继器和一个称为叶子的终端组成。由于其中继功能(跳频功能),它可以覆盖广泛的范围。因此,可以建立最多1000个单位的网状网络-支持信道跳频的多跳网状网络,具有通过自动路由(能够自动切换路由)避免无线干扰的能力。这个特点使它非常适合社会基础设施应用,如交通和路灯,建立覆盖整个城市的远程管理系统。该Click board™使用UART接口与MCU通信,具有常用的UART RX、TX和硬件流控制引脚UART CTS和RTS(发送和接收)。默认情况下,它以115200 bps的速度与主机MCU进行数据传输和交换。此外,额外的板载测试点TP1和TP2通过串行线调试接口为用户提供了完整的

调试和编程功能,可通过SWD接口引脚(SWCK和SWD)进行编程和调试。除了适当的接口,该Click board™还具有一些其他特性。一个连接到mikroBUS™插座的RST引脚的复位按钮将模块置于复位状态,而标有STATUS的蓝色LED指示灯表示广播传输状态的LED指示灯。该Click board™只能在3.3V逻辑电压电平下操作。在使用不同逻辑电平的MCU之前,必须通过适当的逻辑电压电平转换进行。然而,该Click board™配备了一个包含函数和示例代码的库,可供进一步开发时参考。

 * @file main.c
 * @brief Wireless SUN Click Example.
 *
 * # Description
 * This example demonstrates the use of Wireless SUN click board by showing
 * the communication between the two click boards configured as BORDER and ROUTER.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and configures the click board by performing a hardware reset
 * and a clear parameters feature, and setting the device network name, device role to
 * BORDER or ROUTER depending on the application mode. In the end, it saves settings and
 * reboots device.
 *
 * ## Application Task
 * Depending on the selected application mode, it reads all the received data and parses
 * the received TCP/UDP messages (BORDER mode) or waits for the connection, reads the parent
 * global address, and then starts sending a desired TCP/UDP messages to the parent every
 * 3 seconds (ROUTER mode).
 *
 * ## Additional Function
 * - static void wirelesssun_clear_app_buf ( void )
 * - static err_t wirelesssun_process ( void )
 * - static err_t wirelesssun_rsp_check ( void )
 * - static void wirelesssun_wait_for_connection ( void )
 * - static void wirelesssun_get_parent_gbl_address ( uint8_t *gbl_addr )
 *
 * @note
 * By default, the BORDER application mode is selected. comment out the DEMO_APP_BORDER macro
 * definition in order to switch the application mode to ROUTER.
