https://devzone.nordicsemi.com/f/nordic-q-a/36670/flash-memory-layout-for-nrf52832-with-mesh-and-bootloaderI am transitioning a project from normal BLE to BLE mesh. Flash space might be an issue. Here is the flash layout I have so far. Purple is for nordic items and yellow is for my items.

You can have a look at <a href="https://raw.githubusercontent.com/NordicSemiconductor/nRF5-SDK-for-Mesh/b7384b5a500da2357591679f95d53ca175fe1c80/doc/getting_started/how_to_nordicSDK.md">this&nbsp;document.</a></p> <p>Usually the flash manager put the defrag page right after the bootloader. Please have a look at flash_manager_defrag_init()</p> <p>You need to configure&nbsp;FLASH_MANAGER_RECOVERY_PAGE_OFFSET_PAGES to give space for your application plus the fstorage if you use fstorage.&nbsp;</p><div style="clear:both;"></div>
