A phenomenon in which NUS's Central stops midway while performing a BLE scan.

[David_Kim]

hello.

I have two NUS Centrals running at the same time. BLE Scan continues to run during standby.

static void scan_start(void)
{
    ret_code_t ret;

    printf("> Scanstart ");
    ret = nrf_ble_scan_start(&m_scan);
    APP_ERROR_CHECK(ret);

    Bsp_led_indication_Scanning_clr();
    ret = bsp_indication_set(BSP_INDICATE_SCANNING); // connection LED
    APP_ERROR_CHECK(ret);

}

The problem is that when the peripheral PCB is turned on while the two Centrals are performing BLE Scan,
One connection is made to the Central, and the other one stops while scanning.

There is no problem with other operations, only the BLE Scan stops.

Why is this like this?

Also, is there a way to check whether BLE SCAN is operating and restart it if BLE SCAN is stopped?
