device name

[JayPRab]

Hi,

• I am developing a device using the PCA10028 Dev Kit
• It is configured as a BLE Central, SDK 7.2, SD 120
• I am starting out with the example "ble_app_hrs_c_s120_pca10028"
• I have a DIFFERENT device that advertises as follows:
• It says "SHNxxxxxxxx" where the "xxxxxxxx" is the MAC address of the chip
• This allows me to know that the device is one of mine, since it prepends the SHN to the MAC adderss
• When I scan using nRF Toolbox's UART, I can see my device as SHN3E96E1AE, for example
• Below that, it also shows me the MAC address: EE:47:3E:96:E1:AE
• My question is this:
  • How do I get the SHN3E96E1AE in my BLE Central device?
• I can get the MAC address just fine
• I can also get the RSSI
• but I can't find the SHN....
• I don't even know what to call that, when I search on line
• When I obtain the Device Name from the advertising info, I get "NRF51822"....

Thanks for your help!

Hi,

The advertised name can be parsed from the advertising data in the advertising report, as shown in ble_app_multilink_central example:

case BLE_GAP_EVT_ADV_REPORT:
    {
        data_t adv_data;
        data_t type_data;

        // Initialize advertisement report for parsing.
        adv_data.p_data = p_ble_evt->evt.gap_evt.params.adv_report.data;
        adv_data.data_len = p_ble_evt->evt.gap_evt.params.adv_report.dlen;

        err_code = adv_report_parse(BLE_GAP_AD_TYPE_COMPLETE_LOCAL_NAME,
                                  &adv_data,
                                  &type_data);
        if (err_code != NRF_SUCCESS)
        {
            // Compare short local name in case complete name does not match.
            err_code = adv_report_parse(BLE_GAP_AD_TYPE_SHORT_LOCAL_NAME,
                                      &adv_data,
                                      &type_data);
        }
    }

Best regards,
Jørgen

It should all be documented in the SDK and softdevice API reference documentation. Note that this is a very old version of our SDK. I would recommend upgrading to a newer version.

Yes, I know it's old, Jorgen...

After we get this stable we intend to move to a more recent version

Thanks for ALL you VERY prompt help!
