Sibles 廣播

Sibles 廣播提供基于 GAP 廣播 API 的簡單 API。 用戶可以配置部分參數(shù)然后可以開始廣播。

• 配置廣播模式以確定廣播行為。
  • SIBLES_ADV_CONNECT_MODE，啟動(dòng)可連接廣播以建立鏈接。
  • SIBLES_ADV_BROADCAST_MODE，啟動(dòng)不可連接的廣播廣播。
  • SIBLES_ADV_DIRECTED_CONNECT_MODE，為專用鏈接建立啟動(dòng)定向廣播。
• 為每種模式配置參數(shù)，例如間隔、持續(xù)時(shí)間和是否重復(fù)。
• 將廣播數(shù)據(jù)和掃描響應(yīng)數(shù)據(jù)設(shè)置為提供的結(jié)構(gòu)。

這是示例：

// Declare app advertising context
SIBLES_ADVERTISING_CONTEXT_DECLAR(g_app_advertising_context);
 
// Listen the advertising status changed and request.
static uint8_t app_advertising_event(uint8_t event, void *context, void *data)
{
    switch (event)
    {
        case SIBLES_ADV_EVT_ADV_STARTED:
        {
            // Check current started advertising mode
            sibles_adv_evt_startted_t *evt = (sibles_adv_evt_startted_t *)data;
            rt_kprintf("ADV start resutl %d, mode %d\r\n", evt->status, evt->adv_mode);
            break;
        }
        case SIBLES_ADV_EVT_ADV_STOPPED:
        {
            // Check current stopped advertising mode
            sibles_adv_evt_stopped_t *evt = (sibles_adv_evt_stopped_t *)data;
            rt_kprintf("ADV stopped reason %d, mode %d\r\n", evt->reason, evt->adv_mode);
            break;
        }
        default:
            break;
    }
        return 0;
}
