Agree with you, especially on the serial number. This should be random generated, for instance derived from NRF_FICR->DEVICEADDR or any other unique register to avoid any issues by connecting two "equal" devices to the same system. I'll create a bug for this.

*edit*: There is a function for randomizing the serial number present in app_usbd_serial_num.c, which is used if you set your app_usbd_string_config.h::APP_USBD_STRING_SERIAL_EXTERN 1 and "APP_USBD_STRING_SERIAL g_extern_serial_number"

Cheers,

Right, which is why it is strange that the serial number is defined in an SDK config file.

Individual devices are identified by serial number. You want that feature as soon as you connect more than one to the same computer.

Even for the serial number?

Side question, is the serial number field meant for identifying individual devices or for identifying a product?

Hi,

Unfortunately, there isn't an option to do so. You'll have to edit the _config.h file. You could wrap it around a #ifndef APP_USBD_STRINGS_MANUFACTURER \ #define .... \ #endif.

Best regards,

Håkon

Is there a way to set these without editing the SDK files? There doesn't seem to be a macro settings that is set up to prevent redefinition if I try to to define them on my own.

Hi,

It's set in the file app_usbd_string_config.h, in this path:

$SDK/examples/peripheral/usbd_audio/config

Cheers,
