If for some reason you need to use 1600 then I suggest you stop the scanning when you write to flash and start it again when done writing to flash.</p><div style="clear:both;"></div>RE: nRF52840, nRF5_SDK_15.1.0, running SD , problems using nrf_fstora_sd with scan interval and scan window high like 1600.https://devzone.nordicsemi.com/thread/151767?ContentTypeID=1Fri, 05 Oct 2018 07:38:40 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a70d871a-8987-4952-867e-e6c177d25ba8CRIM<p>Weird! it is working fine with 0X0A0 at both parameters?? Also most of the examples I have seen they have the same value, maybe I have to take a look at the specification and how to optimise the two parameters to the application running. I am just not quite sure how high I can go without loosing the flash function specific 1600ms is not working.&nbsp;</p><div style="clear:both;"></div>RE: nRF52840, nRF5_SDK_15.1.0, running SD , problems using nrf_fstora_sd with scan interval and scan window high like 1600.https://devzone.nordicsemi.com/thread/151762?ContentTypeID=1Fri, 05 Oct 2018 07:24:28 GMT137ad170-7792-4731-bb38-c0d22fbe4515:079bd80a-fa4d-4125-9e96-2cd24e0ddea2Hakon<p>SCAN_INTERVAL and SCAN_WINDOW can&#39;t be the same value, otherwise the soft device will never have time to write to the flash. SCAN_WINDOW needs to be lower than SCAN_INTERVAL.</p><div style="clear:both;"></div>RE: nRF52840, nRF5_SDK_15.1.0, running SD , problems using nrf_fstora_sd with scan interval and scan window high like 1600.https://devzone.nordicsemi.com/thread/151723?ContentTypeID=1Thu, 04 Oct 2018 18:59:16 GMT137ad170-7792-4731-bb38-c0d22fbe4515:24350557-7790-47bb-b111-0865a407ab47CRIM<p>The error code was not saying anything it just announced &quot;flash operation failed&quot; . The error only happens when using the 1600 (1000/0.625) ms in SCAN_INTERVAL and SCAN_WINDOW, changing the two variables to 160ms (0xA0)ms the flash operation is working fine. I was trying everything to make it work with 1600 an finally after a lot of test I was passing by the SCAN parameters several times but compared to other examples they was higher, then I tried to change the SCAN parameters to a value used in other examples and the flash operations was working. The 1600ms was some remersens<span></span> from a project I&nbsp; inherited from another project and I can fine live with the change in SCAN parameters, I was just curios if I had overlooked something otherwise it is a limitation in the SCAN parameters when using the flash and SD together.&nbsp;</p><div style="clear:both;"></div>RE: nRF52840, nRF5_SDK_15.1.0, running SD , problems using nrf_fstora_sd with scan interval and scan window high like 1600.https://devzone.nordicsemi.com/thread/151590?ContentTypeID=1Thu, 04 Oct 2018 07:55:00 GMT137ad170-7792-4731-bb38-c0d22fbe4515:2f000b45-ae01-40ee-a031-d84924b4748bHakon<p>Hello,</p> <p>try to set SCAN_WINDOW to 0x0050.
