    thank you for your answer.i used a softdevice(7.1).and i used"ble_flash_block_write" in ble_flash.c directly.the data was written right when the code run after "ble_flash_block_write".but when i continued running the code.and i watched memory was clear.maybe data was cleared by sdk or sd.and do you have any demo code or other solution for me.thanks
