Set USBD_SERIAL on runtime

[Constantin]

Hi,

we would like to set the USBD_SERIAL according to the device serial, which will be an abbreviated version of the MAC address. I've checked the code and can only find Macros for the setting the APP_USBD_STRING_SERIAL. Is there a way to set a via runtime?

Kind regards,

C.W.

Hi,

Try calling app_usbd_serial_num_generate() in main(), and make sure you in sdk_config.h have

APP_USBD_STRING_SERIAL_EXTERN set to 1

APP_USBD_STRING_SERIAL set to g_extern_serial_number
