Function Documentation

void app_usbd_serial_num_generate ( void  )

Function for generating a default serial number string based on FIRC->DEVICEADDR.

After calling this function, the serial number is ready for the USB driver.

The generated serial number shows up as a 12-hexidecimal-digit string with no delimiters (e.g 123456ABCDEF). The byte string is also printed on the PCA10059 dongle. It is also used as the default advertising address in the SoftDevice.
