Hi Nikos,

[quote user="Nikosant03"]what is the practical usage of this property in Device Name characteristic?[/quote]

You could use it to set or get the device name. There are many similar discussions and use cases on the Devzon.

[quote user="Nikosant03"]why does it exist and how it could be helpful for me?[/quote]

That is one of the characteristics in the Generic Access service which is defined in here. It depends on how/what you want to use it. You can search on Devzon to see other people's use cases.

Thank you Amanda, but still, it is not clear to me what is the practical usage of this property in Device Name characteristic?

I mean, why does it exist and how it could be helpful for me?

Thanks in advance

Hi,

To change the name being advertised as well, you will need to disable, re-initialize, and start advertising again, after you have changed the characteristic with sd_ble_gap_device_name_set().

Hi Amanda and thank you for your answer,

So the Device Name characteristic is actually used to change the name that the device is advertising?
