Dear reader,
I'm making my first steps with the DA14580 chip and I use the DSPS code to communicate between a smartphone and a micro-controller that is connected to a PAN1740 (a.k.a. DA14580-01).
I would like to change the name of the device and add the lower 4 bytes of the unique ID of the DA14580.
What is the correct way of changing the NVDS record? Is this the only place to change? Is there a function to read the unique ID?
Anyone who could give direction on how to achieve this within the current release of the DSPS code for the DA14580?
Cheers,
Roland

Hi roland,
In all the SDK5 application you can change the advertising string and the device's name in the NVDS by changing the user_config.h file and the corresponding definition USER_ADVERTISE_DATA and USER_DEVICE_NAME. About thedevice's unique ID i suppose that you mean the bd address of the device, you can change it from theCFG_NVDS_TAG_BD_ADDRESS。nvd处理function is the custom_nvds_get_func() function in the nvds.c file which is called by the jump table, for the bd address get invokation case if the bd address isn't populated by the OTP (nvds_read_bdaddr() gets the be address value from the OTP) and is filled with zeros then the NVDS value (hard coded value in fw) takes place in the NVDS structure.
