nRF Stop scanning coded phy beacon

[saurabh_embrill]

Hello,

Currently using nrf connect sdk version 3.0.0 and nRF5340,
After some random time my device stop scanning coded phy beacon, it not coming in scan callback,
I attached my configuration related to scanning,

Thanks and regards,
Saurabh.

#define CONFIG_BT_LE_SCAN_TYPE  BT_LE_SCAN_TYPE_PASSIVE         /**< Scan type (BT_LE_SCAN_TYPE_ACTIVE or BT_LE_SCAN_TYPE_PASSIVE). */
#define CONFIG_BT_LE_SCAN_OPT  BT_LE_SCAN_OPT_CODED  /**< Bit-field of scanning options. */
#define CONFIG_BT_GAP_SCAN_INTERVAL BT_GAP_SCAN_FAST_INTERVAL_MIN   /**< Scan interval (N * 0.625 ms). */
#define CONFIG_BT_GAP_SCAN_WINDOW   BT_GAP_SCAN_FAST_WINDOW   /**< Scan Window (N * 0.625 ms). */

static struct bt_le_scan_param scan_param = {
    .type = CONFIG_BT_LE_SCAN_TYPE,
    .options = CONFIG_BT_LE_SCAN_OPT,
    .interval = CONFIG_BT_GAP_SCAN_INTERVAL,
    .window = CONFIG_BT_GAP_SCAN_WINDOW,
    .interval_coded = CONFIG_BT_GAP_SCAN_INTERVAL,
    .window_coded = CONFIG_BT_GAP_SCAN_WINDOW,
    .timeout = 30000, /** Scan stop after 5 minutes. 10.9 is (Maximum) */
};

struct bt_le_scan_cb scan_cb_struct = {
    .recv = ble_scan_cb,
    .timeout = ble_scan_timeout_cb,
};

static void ble_scan_timeout_cb(void)
{
    LOG_INF("scan stop timeout restart bluetooth scanning");\
    k_work_submit(&start_scan_work);
    // ble_start_scanning();
}

// Register callback function
err = bt_le_scan_cb_register(&scan_cb_struct);

// Start scanning
err = bt_le_scan_start(&scan_param, NULL);

Hi,

There is a known issue in the SoftDevice Controller where sometimes stopped generating advertising reprots when doing extended scanning (like scanning coded PHY). This is fixed in nRF Connect SDK 3.1.0, so i recommend updateing to that or later.
