hello_client_advertisement_report rate slows down badly

I modified hello_client to get a master listening to advertisements sent by another CYW20737 client (every 250ms)

Initially hello_client_advertisement_report is called every 250ms, but after 30 seconds this rate slows down, and gets only called once every 5..15 seconds. The client is still sending it every 250ms, verified by Android.

To be sure I also disabled all traces by: bleapp_trace_enable=0;

Any idea what is causing the drastic slow down?

Hi,

I could not find the sampe which you are describing above. However all BLE samples have wiced_bt_cfg.c file in the same folder.

This file has timing parameter for adv and scan interval.

   .ble_advert_cfg =                  /**< BLE advertisement settings */

    {

        .channel_map                     = ( BTM_BLE_ADVERT_CHNL_37 | BTM_BLE_ADVERT_CHNL_38 | BTM_BLE_ADVERT_CHNL_39 ),    /**< Advertising channel map (mask of BTM_BLE_ADVERT_CHNL_37, BTM_BLE_ADVERT_CHNL_38, BTM_BLE_ADVERT_CHNL_39) */

        .high_duty_min_interval          = WICED_BT_CFG_DEFAULT_HIGH_DUTY_ADV_MIN_INTERVAL,          /**< High duty undirected connectable advert minimum advertising interval (default: WICED_BT_CFG_DEFAULT_HIGH_DUTY_ADV_MIN_INTERVAL) */

        .high_duty_max_interval          = WICED_BT_CFG_DEFAULT_HIGH_DUTY_ADV_MAX_INTERVAL,          /**< High duty undirected connectable advert maximum advertising interval (default: WICED_BT_CFG_DEFAULT_HIGH_DUTY_ADV_MAX_INTERVAL) */

        .high_duty_duration              = 60,                                                       /**< High duty advertising duration in seconds (0 for infinite) */

        .low_duty_min_interval           = WICED_BT_CFG_DEFAULT_LOW_DUTY_ADV_MIN_INTERVAL,           /**< Low duty undirected connectable advert minimum advertising interval (default: WICED_BT_CFG_DEFAULT_LOW_DUTY_ADV_MIN_INTERVAL) */

        .low_duty_max_interval           = WICED_BT_CFG_DEFAULT_LOW_DUTY_ADV_MAX_INTERVAL,           /**< Low duty undirected connectable advert maximum advertising interval (default: WICED_BT_CFG_DEFAULT_LOW_DUTY_ADV_MAX_INTERVAL) */

        .low_duty_duration               = 60,                                                       /**< Low duty advertising duration in seconds (0 for infinite) */

        .high_duty_directed_min_interval = WICED_BT_CFG_DEFAULT_HIGH_DUTY_DIRECTED_ADV_MIN_INTERVAL, /**< high duty directed adv minimum advertising interval (default: WICED_BT_CFG_DEFAULT_HIGH_DUTY_DIRECTED_ADV_MIN_INTERVAL) */

        .high_duty_directed_max_interval = WICED_BT_CFG_DEFAULT_HIGH_DUTY_DIRECTED_ADV_MAX_INTERVAL, /**< high duty directed adv maximum advertising interval (default: WICED_BT_CFG_DEFAULT_HIGH_DUTY_DIRECTED_ADV_MAX_INTERVAL) */

        .low_duty_directed_min_interval  = WICED_BT_CFG_DEFAULT_LOW_DUTY_DIRECTED_ADV_MIN_INTERVAL,  /**< Low duty directed adv minimum advertising interval (default: WICED_BT_CFG_DEFAULT_LOW_DUTY_DIRECTED_ADV_MIN_INTERVAL) */

        .low_duty_directed_max_interval  = WICED_BT_CFG_DEFAULT_LOW_DUTY_DIRECTED_ADV_MAX_INTERVAL,  /**< Low duty directed adv maximum advertising interval (default: WICED_BT_CFG_DEFAULT_LOW_DUTY_DIRECTED_ADV_MAX_INTERVAL) */

        .low_duty_directed_duration      = 30,                                                       /**< Low duty directed advertising duration in seconds (0 for infinite) */

        .high_duty_nonconn_min_interval  = WICED_BT_CFG_DEFAULT_HIGH_DUTY_NONCONN_ADV_MIN_INTERVAL,  /**< High duty non-connectable adv minimum advertising interval (default: WICED_BT_CFG_DEFAULT_HIGH_DUTY_NONCONN_ADV_MIN_INTERVAL) */

        .high_duty_nonconn_max_interval  = WICED_BT_CFG_DEFAULT_HIGH_DUTY_NONCONN_ADV_MAX_INTERVAL,  /**< High duty non-connectable adv maximum advertising interval (default: WICED_BT_CFG_DEFAULT_HIGH_DUTY_NONCONN_ADV_MAX_INTERVAL) */

        .high_duty_nonconn_duration      = 30,                                                       /**< High duty non-connectable advertising duration in seconds (0 for infinite) */

        .low_duty_nonconn_min_interval   = WICED_BT_CFG_DEFAULT_LOW_DUTY_NONCONN_ADV_MIN_INTERVAL,   /**< Low duty non-connectable adv minimum advertising interval (default: WICED_BT_CFG_DEFAULT_LOW_DUTY_NONCONN_ADV_MIN_INTERVAL) */

        .low_duty_nonconn_max_interval   = WICED_BT_CFG_DEFAULT_LOW_DUTY_NONCONN_ADV_MAX_INTERVAL,   /**< Low duty non-connectable adv maximum advertising interval (default: WICED_BT_CFG_DEFAULT_LOW_DUTY_NONCONN_ADV_MAX_INTERVAL) */

        .low_duty_nonconn_duration       = 0,                                                        /**< Low duty non-connectable advertising duration in seconds (0 for infinite) */

    },

Modifying these parameter which is relevant for you may help.

Regards.
