蓝牙初始化:

void do_ble_init(void){
    // Initialize BLE controller
    LOGI(TAG, "do_ble_init ");
    ble_controller_init(configMAX_PRIORITIES - 1);
    //Initialize BLE Host stack
    hci_driver_init();
    bt_enable(bt_ready_cb);
    bt_set_name("LVS-Lush122-XT");
    bt_gatt_service_register((struct bt_gatt_service *)&dis);
    notify_attrs = &ble_attrs[1];
    bt_conn_cb_register(&conn_callbacks);
    ble_start_advertise();
}

蓝牙接收到的数据处理:

    }
        ret_str[3]=';';
        do_ble_notify(conn, ret_str, strlen(ret_str));//设备蓝牙回复当前电量

    }
    
    else if(CDM_CMP(cmd,"Light")){      //灯光闪烁开关
        if(data[0]=='o'&&data[1]=='n'){

        sleep_start();   
    }

    else if(CDM_CMP(cmd,"OTA")){         //蓝牙发送  OTA;   进入OTA
    LOGI(TAG, "OTA");

    wifi_setup_sta();
    ota_time= hal_timer_now_s();          //记录OTA开始的时间
    char ota_ret[20]="OTA_START";

    }

    else if(CDM_CMP(cmd,"WIFI")){          //蓝牙配网指令: "WIFI:账号,密码;"
    LOGI(TAG, "SET WIFI ");

    }
    }
    vTaskDelay(100 / portTICK_RATE_MS);

    //do_ble_notify(conn, ret_str, strlen(ret_str));
}

对蓝牙下发的指令进行解析,根据解析后的指令经行震动马达和灯光的控制:

void mada_task(void *arg){         //mada模式

uint32_t duty = 0;
int i=0;
while(1){
    if(!ble_connect&&(charge_status == DISCHARGE)){                        //四档离线模式
        if(Grade==0) motor_g_set_vibrate(0);
        if(Grade==1) motor_g_set_vibrate(8);
        if(Grade==2) motor_g_set_vibrate(12);
        if(Grade==3) motor_g_set_vibrate(16);
        if(Grade==4) motor_g_set_vibrate(20);
    }
    else if(ble_connect&&(charge_status == DISCHARGE)&&Preset==0){          //蓝牙在线模式
        motor_g_set_vibrate(vibrate);
        if(vibrate==0)led_status_flash(0);                                     
    }
    else if(ble_connect&&(charge_status == DISCHARGE)&&Preset!=0){
        memcpy(currentPreMod,presetMod[Preset-1],8);
        for(i=0;i<8;i++){
        duty =currentPreMod[i]*100;
        motor_g_set_duty(duty);
        current_Preset=currentPreMod[i];
        if(light_flag){led_status_flash(115-current_Preset);}                   //9种预设模式灯光,在此实现跟马达同时变化
        vTaskDelay(300 / portTICK_RATE_MS);
        LOGI(TAG, "presetMod:%d",currentPreMod[i]);
    }
    }
    else {motor_g_set_vibrate(0);Grade=0;vibrate=0;}
    vTaskDelay(100/portTICK_RATE_MS);
}
}

9种预设模式变化频率,可以在此调整每个模式下的震动频率变化

const uint8_t presetMod[9][8] =
{
        { 100, 20, 100, 20, 100, 20, 100, 20 },     //Mod1
        { 50, 100, 50, 100, 50, 100, 50, 100 },     //Mod2
        { 40, 60, 80, 100, 100, 80, 60, 40 },       //Mod3
        { 100, 25, 100, 25, 100, 25, 100, 25 },     //Mod4
        { 75, 100, 75, 100, 75, 100, 75, 100 },     //Mod5
        { 20, 100, 60, 100, 60, 100, 30, 60 },      //Mod6
        { 75, 30, 20, 30, 100, 30, 25, 60 },        //Mod7
        { 100, 100, 100, 100, 100, 100, 100, 100 }, //Mod8
        { 38, 100, 80, 47, 28, 20, 28, 44 },        //Mod9
};

自动低功耗休眠任务:

void sleep_task(void *arg){           //大于1200S无震动,进入休眠模式
static int times=0;
while(1){
//LOGI(TAG, "start sleep");
    if(Grade==0&&vibrate==0&&(charge_status == DISCHARGE)&&Preset==0) times++;
    else times=0;
    if(ota_flag) times =0;

   //LOGI(TAG, "times:%d",times);

    while(times>1200) {        
        hal_hbn_init(&key_weakup_pin, 1);
        hal_hbn_enter(0);}
    while(ota_flag&&(hal_timer_now_s()-ota_time>300)){
        hal_hbn_init(&key_weakup_pin, 1);
        hal_hbn_enter(0);
    }
        vTaskDelay(1000 / portTICK_RATE_MS);
}

}
