Demo功能

1、基于我司的現(xiàn)場(chǎng)Nordic52840的PCBA構(gòu)建的藍(lán)牙m(xù)esh中所有節(jié)點(diǎn)為同一類型，任一節(jié)點(diǎn)都可以控制網(wǎng)絡(luò)中所有設(shè)備
2、任一節(jié)點(diǎn)的加入及去除不影響整個(gè)網(wǎng)絡(luò)的工作。
3、在節(jié)點(diǎn)中通過一個(gè)節(jié)點(diǎn)publish一個(gè)切換當(dāng)前l(fā)ight狀態(tài)的指令，當(dāng)訂閱的設(shè)備收到此信息后直接trigger一下light的狀態(tài)

需要設(shè)備

1、需要5個(gè)我司的5個(gè)PCBA
2、需要手機(jī)按照mesh的APP后代配網(wǎng)用

實(shí)現(xiàn)方法

基于light_switch的example來實(shí)現(xiàn)，在client的demo中移植server部分的功能，并將server中l(wèi)ight中的功能按照新的PCBA重新配置GPIO
同時(shí)需要注意原來demo中關(guān)于GPIO配置驅(qū)動(dòng)有著局限性問題（只能配置為P0,且LED的多個(gè)GPIO需要是連續(xù)的，需要重新修改驅(qū)動(dòng)）

具體步驟

（1）移植server部分代碼

/* Generic OnOff server structure definition and initialization */
APP_ONOFF_SERVER_DEF(m_onoff_server_0,
                     APP_CONFIG_FORCE_SEGMENTATION,
                     APP_CONFIG_MIC_SIZE,
                     app_onoff_server_set_cb,
                     app_onoff_server_get_cb)

/* Callback for updating the hardware state */
static void app_onoff_server_set_cb(const app_onoff_server_t * p_server, bool onoff)
{
    /* Resolve the server instance here if required, this example uses only 1 instance. */

    __LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "Setting GPIO value: %d\n", onoff)

    //hal_led_pin_set(BSP_LED_GREEN, onoff);
    LED_Toggle();
}

/* Callback for reading the hardware state */
static void app_onoff_server_get_cb(const app_onoff_server_t * p_server, bool * p_present_onoff)
{
    /* Resolve the server instance here if required, this example uses only 1 instance. */

    *p_present_onoff = hal_led_pin_get(BSP_LED_GREEN);
}
static void models_init_cb(void)
{
    __LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "Initializing and adding models\n");

    for (uint32_t i = 0; i < CLIENT_MODEL_INSTANCE_COUNT; ++i)
    {
        m_clients[i].settings.p_callbacks = &client_cbs;
        m_clients[i].settings.timeout = 0;
        m_clients[i].settings.force_segmented = APP_CONFIG_FORCE_SEGMENTATION;
        m_clients[i].settings.transmic_size = APP_CONFIG_MIC_SIZE;

        ERROR_CHECK(generic_onoff_client_init(&m_clients[i], i + 1));
    }
    app_model_init();
}

（2）手機(jī)配置過程

每個(gè)設(shè)備有三個(gè),element包含client和server

client的配置如下，所有節(jié)點(diǎn)的client的publish的組地址定為0xc000

server的配置如下，所有節(jié)點(diǎn)的server的訂閱的組地址client的publish地址一致，為0xC000

(3)功能測(cè)試

實(shí)現(xiàn)了預(yù)想功能，仍一節(jié)點(diǎn)按下按鍵后，剩余所有節(jié)點(diǎn)切換light開發(fā)狀態(tài)
