Unable to print BLE devices Complete local Name?

[sankeerthan]

Hi, I am trying to print ble device names around my board by scanning and i am able to print some devices and i am unable to print other device names even though they are advertising but by printing through device address i am able to print all the devices addresses,even though it has complete local name available i am unable to print it's name.

please tell me why if i print addresses i am able to see that device but why not by printing device name?? Thank you

Hi,

Not all devices have a device name. A device name is not mandatory. In nRF-Connect devices without a name are shown as N/A. I suggest using the adv_report_parse() function from the ble_app_hrs_c example in the SDK to check if the device have a valid device name.

Hi, ya some devices with N/A they are not advertising through name that is fine but for some devices i am able to see device name in nRF-Connect but not through my board(nRF52840) while scanning.

Thank You.

What SDK version is this ? Are you basing your code on the ble_app_hrs_c example? What kind of devices are you not able to find?

Try to do something like this:

Code snippet:

//search for advertising names
err_code = adv_report_parse(BLE_GAP_AD_TYPE_COMPLETE_LOCAL_NAME, &adv_data, &dev_name);
if (err_code == NRF_SUCCESS)
{
           
    NRF_LOG_RAW_HEXDUMP_INFO(dev_name.p_data,dev_name.data_len);
.
.   
.

i am using ble_app_hrs_c_pca10056_s140(nRF52840) and SDK is 14.0.0,and i am uable to fine devices like prontos,Remotes(which are ble devices).

But you are able to find the device addresses of these devices?
