</pre>
</details>
<details><summary>Q: How to connect to wifi?</summary>A: FirstlyRefer to <a target="_blank" rel="nofollow noreferrer noopener" class="external text" href="https://docs.pikvm.org/first_steps/">Optional setting up Wi-Fi</a><br>If you want to connect PiKVM to a Wi-Fi network, insert you need to tell the C1220 button batterydevice ESSID and password before first boot.run To do this, mount the first partition of the memory card (FAT32) and edit or make the following command: rw sudo nano /boot/configpikvm.txt #Then change the file there. Do not remove line: '''dtoverlayFIRSTBOOT=i2c1 or FIRST_BOOT-rtc1 for first time booting,pcf8563just add your wifi settings like this:<pre>FIRSTBOOT=1WIFI_ESSID='mynet'' to '''dtoverlayWIFI_PASSWD=i2c-rtc,ds1307''p@s$$w0rd' </pre> #Test RTC #Display There is a possibility that, in countries that support CH13, the current time of the Raspberry Pi date #Write the time of Raspberry Pi device will not connect. You will need to configure your router to DS1307 sudo hwclock disable channels 12-w #Read the time of DS1307 sudo hwclock -r ro14 or disable Auto scan mode so it will connect.
