how to add the feature of flashwriter to app_ble_beacon?

[zouxh]

I have a PCA10040 board and use the development soft of SEGGER Embedded Studio for ARM 4.50.

I ran the project  \nRF5_SDK_15.3.0_59ac345\examples\ble_peripheral\ble_app_beacon

and \nRF5_SDK_15.3.0_59ac345\examples\peripheral\flashwrite successfully.

Now I want creat a new project having both feature of flashwriter and app_ble_beacon.

I added the source of flashwriter to app_ble_beacon,and passed the building, but it is always appeared error.

I don't know how to modify them.

Best regard

Hi,

Access to the NVMC is restricted as long as the softdevice is enabled because flash operations may block the Softdevice and thus interfere with timing-critical protocol events. So the flashwrite implementation which relies on direct access to the NVMC is not compatible with Bluetooth applications.  I recommend reading through the Flash memory API chapter of the Softdevice specification for a bit more background on this limitation.

When the Softdevice is present you can use the  sd_flash_*() APIs instead. You may also consider using fstorage/fds on top to manage the flash storage, especially if you intend to store data to flash frequently.

Best regards,

Vidar
