There is this https://github.com/NordicSemiconductor/IOS-Pods-DFU-Library/pull/374 PR, which introduces the same flag as I added recently to Android DFU Library. For now you may use this branch, I’ll try to release the new version for iOS today.

The issue you have is the same as #234. The problem is, that on some phones, mainly Samsung with recent Android versions, the direct advertising performed by the bootloader misses the phone, and in result the phone never connects. From the log above I see, that your bootloader is advertising with the same address as in the app mode, and as you use Legacy DFU, most probably (unless you change something in the fw), it’s using direct advertising. For me this looks like a bug on those phones. Perhaps they use the same controller (Bluetooth chip), or the root cause is somewhere in the stack. For you to make it work you need to:

Use other phone, e.g. from Pixel family.
Looks like your device is not bonded. In my opinion, that will work when you use bonding, as then connection to devices advertising directly should work.
To allow updating from Samsung phone, you need to modify your app or bootloader on the device. Either you make the app (buttonless service) not to pass peer data to the bootloader, or you modify the bootloader to always use address +1. When you modify one of them, use the new API available in 1.11.0: https://github.com/NordicSemiconductor/Android-DFU-Library/blob/d1de47b24ca600f4273afc8ed1cb48dca45e9b4d/dfu/src/main/java/no/nordicsemi/android/dfu/DfuServiceInitiator.java#L289-L310 That will make the library scan for the bootloader. I guess you already did it.

Hint how to modify the buttonless service on your device is below. You need to comment out the dfu_app_peer_data_set(conn_handle);:

/**@brief Function for preparing the reset, disabling SoftDevice, and jumping to the bootloader.
 *
 * @param[in] conn_handle Connection handle for peer requesting to enter DFU mode.
 */
static void bootloader_start(uint16_t conn_handle)
{
    uint32_t err_code;
    uint16_t sys_serv_attr_len = sizeof(m_peer_data.sys_serv_attr);

    err_code = sd_ble_gatts_sys_attr_get(conn_handle,
                                         m_peer_data.sys_serv_attr,
                                         &sys_serv_attr_len,
                                         BLE_GATTS_SYS_ATTR_FLAG_SYS_SRVCS);
    if (err_code != NRF_SUCCESS)
    {
        // Any error at this stage means the system service attributes could not be fetched.
        // This means the service changed indication cannot be sent in DFU mode, but connection
        // is still possible to establish.
    }

    m_reset_prepare();

    err_code = sd_power_gpregret_set(BOOTLOADER_DFU_START);
    APP_ERROR_CHECK(err_code);

    err_code = sd_softdevice_disable();
    APP_ERROR_CHECK(err_code);

    err_code = sd_softdevice_vector_table_base_set(NRF_UICR->NRFFW[0]);
    APP_ERROR_CHECK(err_code);

    // Prevent application from sharing Peer Data with Bootloader
    //dfu_app_peer_data_set(conn_handle);

    NVIC_ClearPendingIRQ(SWI2_IRQn);
    interrupts_disable();
    bootloader_util_app_start(NRF_UICR->NRFFW[0]);
}

If you already have devices in production with the default implementation, you need to allow users to update it either with a button (when buttonless service is not used, the bootloader will advertise with address+1, so scanning for DfuTarg device is required. Start DFU for the new found device), or use a phone that works. When I tested it, it worked 100% on some phones and only sometimes failed on others, but I don’t have Samsung S9 with me.
