Hi All,
I wonder what are the best options to have persistent storage for QN9090.
As there is no EEPROM, the only way is using one or a few of the FLASH sectors.
I can't find any sample code for data storage.
Or .. Should I use external EEPROM?
Thanks,
Mike

Hi MikeCalm,
About the internal flash operation, we have the SDK which contains the flash_demo, that project will help you to finish the flash program, erase, read operation.
You can download the SDK code from this link:
Choose board as QN9090DK6 , and download SDK_2.6.1_QN9090DK6.
You can find the flash code in folder:
SDK_2.6.1_QN9090DK6\boards\qn9090dk6\driver_examples\flash
But, as you know , the on chip flash has the endurance limit:
If your eeprom data is write frequently, I suggest you to use the external EEPROM with I2C interface.
Wish it helps you!
If you still have questions about it, please kindly let me know!
Best Regards,
Kerry
