Natenczas Wojski in UDS

[tldr]

I ran across my devices reporting 

Natenczas Wojski

from a UDS service that was included when running a sample HRS 
https://www.bluetooth.com/specifications/specs/user-data-service-1-1/

others have taken screen captures of it and asked of its existence/purpose.
https://github.com/dotintent/FlutterBleLib/issues/527 

I have looked all over the trees looking for this name and I do not see it.

Does anyone know why this name is being broadcast as default from nrf samples?

joke from RFconnect?

I dont see much on the forums about UDS.

I could not change the name using the code...and we're being pointed towards hrs sample.

Hi, 

Which NCS version and sample are you using?

Could you provide the path for the sample?

The peripheral_hr doesn't include the UDS service.

Please elaborate in more detail on how to reproduce the issue. 

Regards,
Amanda H.

[tldr]

This is a project that I created from multiple samples, I believe it came in with prj.conf

CONFIG_BT_BAS=y

CONFIG_BT_HRS=y

I will check more later when I can test.  I'm using v2.6.0.

Connect with nrfconnect app, connect to device, goto server tab.  0x181C is there with these silly defaults.  Or maybe I'm picking it up elsewhere, let me know I can tear it apart a bit more to try and isolate it.

I don't see that with the NCS v2.6.0 peripheral_hr. 

You could try to reflash service from the top right corner. 

[tldr]

peripheral_hr isn't what I started with.  There's another unknown service 0000aaa0-0000-1000-8000-aabbccddeeff that I can't account for either.

DK_LIBRARY or SAMPLES_DEFAULTS or something is implementing these services...and I didn't really do too much.

there is no reflash service in that three dot drop down.  I see a refresh and that doesn't help.

Ok.  Not fun troubleshooting this.

CONFIG_BT=y
CONFIG_BT_BROADCASTER=y
CONFIG_BT_OBSERVER=y
CONFIG_BT_PERIPHERAL=y

my code is a peripheral, broadcaster, and observer.  I don't know what is adding this UDS service.  I guess I will try to reproduce in peripheral_hr 

¯\_(ツ)_/¯ i didn't pull any outside code.

I may just live with it for now.  Just FYI there's other people seeing this name / service and confused by it too.  If you want the full code, I can send it privately.  I'm using an NRF5340DK and the thingy53.

Where do you get the sample? Could you share the link or Could you upload the project via Insert-> Image/Video/files from the toolbar?

[tldr]

I pulled out all the HRS and battery stuff, I still see a (predefined) Heart Rate and (predefined) Current Time Services.

[tldr]

I just ran C:\ncs\v2.6.0\zephyr\samples\bluetooth\peripheral_hr and it shows these predefined services and UDS with these names?  Im confused how this could be.  I did a diff on the peripheral_hr files they are the same.

Hi, 

I have tested your project and peripheral_hr, and don't get like your figures. 

You probably load the GATT server setting in the app. You could disable it from the left corner of the app -> Configure GATT server -> Disable

[tldr]

THANK YOU!!!  I don't know what the GATT server is for or how I enabled it, but that was it!

[Amanda Hsieh]

Good to know it works.
