https://devzone.nordicsemi.com/f/nordic-q-a/36454/flashwritei need use flashwrite in my code, but i found sometims when i write data in flash, the BLE connecting sometimes is borken, i used this funciton flash_word_write(uint32_t * address, uint32_t value) it was said when you need to use softdevise , you needen-USTelligent Community 13Mon, 16 Jul 2018 06:39:00 GMThttps://devzone.nordicsemi.com/thread/140156?ContentTypeID=1Mon, 16 Jul 2018 06:39:00 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f8be0934-e894-4f47-b8e5-90fc07676043Adrian Eggenberger<p>Hi</p> <p>If you use a softdevice you need to use the dedicated flash access functions the softdevice provides itself. Normally these are the functions &quot;sd_flash_write&quot; and &quot;sd_flash_erase_page&quot;. The specification for these functions can be found in the Nordic InfoCenter in the Softdevice documentation.</p> <p>Keep in mind that these two functions only start the write/erase operation. Once the operation has been completed (or failed) the softdevice interrupt is triggered and a event can be read from the event queue of the softdevice.</p> <p>The Nordic&#39;s SDK provides some higher level libraries for flash access with or without softdevice usage (check out fstorage library in the SDK). These high level API can be used, but it&#39;s also possible to use the softdevice functions directly as we do in our projects.&nbsp;</p> <p>Maybe one additional remark. If the BLE is active there is a chance that a flash operation may fail.
