No device name in advertising data.How to get device name?

[daoms]

nRF52 DK,software is nRF5_SDK_12.3.0_d7731ad,I'm using the example of "ble_app_multilink_central". SoftDevice is "s132_nrf52_3.0.0_softdevice.hex"

The BLE device is advertising.

My central(DK Board) cannot get the device name.The function "adv_report_parse"  is failed by "can't parse the data".

So I check the "adv_report.data",it is "0201 0603 1940 0411 069E CADC 240E E5A9 E093 F3A3 B501 0040 6E",obvious there is no name in it.And the "scan_rsp" is always 0,means it is just the advertising data.

But I already set active scan as below

static const ble_gap_scan_params_t m_scan_params =
{
.active = 1,
.interval = SCAN_INTERVAL,
.window = SCAN_WINDOW,
.timeout = SCAN_TIMEOUT,...

In nRF Connect ,it is able to scan the device and show its name just by scan(not connected).

So 

1.When no name in advertising data,how to get the the device name? Send a "scan_request "?How to do that?

2.The function "SD_BLE_GAP_DEVICE_NAME_GET" is used for what?What does the DEVICE mean?

Thanks very much.

Are you sure that your device has an advertising name?

 

If you try to compile the ble_app_blinky example found in SDK\examples\ble_peripheral\ble_app_blinky, it is initialized with a name (Nordic_blinky), which is the name that the multilink example is looking for.

No there isn't a advertising name in  its advertising data.

1.So maybe the device name is in its scan_response_data(SCAN_RSP=1),but why ACTIVE_SCAN doesn't work?

2.After connected,it should be abe to get the DEVICE NAME,so how to send the request?

[Edvin]

Do you have scan response data?  What do you mean with active_scan not working? Do you not get any scan responses from the central?

 

I suspect you would have interest of the ble_app_multilink_central example found in:

SDK\examples\ble_central\ble_app_multilink_central

 

Look in the function on_adv_report(...) in main.c, which checks the advertising report for the name. See if you can use this.
