Can't scan extended advertise packets using nrf-ble-driver

[Ivlampiy223]

I use:

• pca10059, connectivity_4.1.1_usb_with_s140_6.1.1.hex
• nrf-ble-driver-4.1.1-win_x86_32

I am trying to scan BLE advertise. I have a problem that ALL packets that i recieve have <31 bytes of data. It is wrong, because i see more data from devices in nRF Connect.

In result i cant parse BLE_GAP_AD_TYPE_COMPLETE_LOCAL_NAME or BLE_GAP_AD_TYPE_SHORT_LOCAL_NAME from devices that use extended advertise. I get name only from scan response packets, but it takes a lot of time. How to get full packets?

Here is my scan config:

SCAN_INTERVAL = 0x00A0,
SCAN_WINDOW = 0x00A0,
SCAN_TIMEOUT = 0x0

uint8_t scan_buffer_data[BLE_GAP_SCAN_BUFFER_EXTENDED_MIN] = { 0 };
ble_data_t mAdvReportBuffer = {
    scan_buffer_data,
    BLE_GAP_SCAN_BUFFER_EXTENDED_MIN
};
const ble_gap_scan_params_t mScanParam = {
    1,
    0,
    1,
    BLE_GAP_SCAN_FP_ACCEPT_ALL,
    BLE_GAP_PHY_1MBPS,
    (uint16_t)SCAN_INTERVAL,
    (uint16_t)SCAN_WINDOW,
    (uint16_t)SCAN_TIMEOUT,
    { 0 }
};

First start scan call:

uint32_t error_code = sd_ble_gap_scan_start(adapter, &mScanParam, &mAdvReportBuffer);

Next scan call in event handler:

errCode = sd_ble_gap_scan_start(adapter, NULL, &mAdvReportBuffer);

Hi

What beacon application is it that you're trying to scan? Do you have the beacon's application code?

The nRFConnect app also uses data from the scan response packet in order to get all the information, as there isn't enough room in a single advertising packet for all that information.

Best regards,

Thank you for answer, Simon!

I am using nRF Connect advertiser and other applications. That was my mistake that i didn't get extended packets. I thought that nRF Connect shows really raw data under "RAW" button. There wasn't extended packets. I tried to create really extended packet and it works perfectly.

So the problem is that i'm getting scan responses slower than nRF Connect app. How to configure it for best perfomance?
