 我在 `main.c` 檔案開頭使用了 `k_cycle_get_32();` 函數取得時間，然後在 `ble_bond.c` 檔案中使用相同的函數再次取得時間。兩次取得的時間相減後，我發現 `0x000163DF` 之後發生了一次清除操作。如何手動執行此清除操作？實驗表明，這會影響按鍵掃描時間。目前版本為 NCS v2.9.2，項目為 nrf_desktop。</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Thu, 12 Mar 2026 03:07:34 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/127303/settings-taking-too-long-to-load-can-affect-the-scan-key-time" /><item><title>RE: Settings taking too long to load can affect the scan key time.</title><link>https://devzone.nordicsemi.com/thread/563068?ContentTypeID=1</link><pubDate>Thu, 12 Mar 2026 03:07:34 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:f9dc0066-beaa-457a-8623-16123c6b379f</guid><dc:creator>Michael Lin</dc:creator><description>&lt;p&gt;This part involves client-side code, so it&amp;#39;s not convenient to disclose it here.

&lt;p&gt;I am glad to hear that.

&lt;p&gt;Can you elaborate on what you are measuring and what the problem is? Settings&amp;nbsp;only need to be loaded once after reset. Also, from what I can see you measure the time from entering main() until that task is performed, but other operations are also done during this time. I am also unsure about the topic: &amp;quot;Settings taking too long to load can affect the scan key time&amp;quot;. Can you elaborate on this, both what you do and what the problem is (also, what is &amp;quot;key scan time&amp;quot;?)&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
