flash_word_erase and flash_word_write just before initializing BLE?!

[Alex Co]

Hi

I have a sample nrf51822 non BLE program (based on flashwrite_example) that successfully writes and reads flash (last flash page) in a loop, incrementing the number that is written. So, it (finally) works well...

Now I would like to put that code in a nrf51822 program that uses BLE/SDv7.

Imagine that per program execution I just need to access flash (erase and write) one time and always before calling ble_stack_init();

Is it safe to use that code to rewrite flash last page (4 bytes) before calling ble_stack_init(); or should I use the ble compliant functions (e.g sd_flash_page_erase)?

Thanks a lot.

When the softdevice is enabled, the softdevice API for accessing flash should be used (sd_flash_page_erase/sd_flash_write).

Note: for writing and handling data storage in flash, the libraries FDS (Flash Data Storage) and  Flash Storage are there to make it easier.

I am using sdk6... no way to use newer one due to uC rev and "unknown behaviour"

But it is ok, I am going to use sd_flash_page_erase/sd_flash_write

Thanks
