Hi @unicorn200066

I could not find "MyBleServer" device on my iphone

Can you confirm that you're still unable to find it when searching with the nRFConnect or the LightBlue apps? Or are you using your own iOS code?

[unicorn200066]

Thank you for your reply
yes，I found nothing in nRFConnect app, I wonder if I made a wrong uuid or I forgot something in my code. I run the code with win10 OS and pyCharm IDE, is there anything I need to fix.

Hi kevincar
I checked in nRFConnect again, I found my computer's name in it and the device information is 180A.
I found that the service's uuid is the same with my code set, however, it showed that it's an unknown Service, not the name of "MyBleServer" defined in my code, why is that?
Plus, how can I let my iphone know this device as the name I defined.
Thank you so much!

Yes, the method for applying the service name to the device is operating system dependent. In other words, Linux, MacOS, and Win10, all apply the name differently and isn't always broadcast the same. The code was last tested on Win11.
