BLE设置广播时间

#define TGAP_LIM_ADV_TIMEOUT                    1   //!< Maximum time to remain advertising, when in Limited Discoverable mode.Default 180 seconds. (n * 1 seconds)

比如设置60s广播时间

GAP_SetParamValue(TGAP_LIM_ADV_TIMEOUT,60);

运行效果

 

 重新开启广播是因为，广播关闭以后会进，重新开启了广播（如果想停，关闭广播即可）

static void hidEmuStateCB(gapRole_States_t newState, gapRoleEvent_t *pEvent)
{
    switch(newState)
    {
              case GAPROLE_WAITING:
            if(pEvent->gap.opcode == GAP_END_DISCOVERABLE_DONE_EVENT)
            {
                PRINT("Waiting for advertising..\n");
            }
            else if(pEvent->gap.opcode == GAP_LINK_TERMINATED_EVENT)
            {
                PRINT("Disconnected.. Reason:%x\n", pEvent->linkTerminate.reason);
            }
            else if(pEvent->gap.opcode == GAP_LINK_ESTABLISHED_EVENT)
            {
                PRINT("Advertising timeout..\n");
            }
            // Enable advertising
            {
                uint8_t initial_advertising_enable = TRUE;
                // Set the GAP Role Parameters
                GAPRole_SetParameter(GAPROLE_ADVERT_ENABLED, sizeof(uint8_t), &initial_advertising_enable);
            }
            break;
    }
}
