@Eric-Katzfey Oh, do you mean I can see the "RTC time" by timedatectl, but it doesn't mean voxl2 has the RTC? I see. Thank you for your answer.

    How to sync RTC to UTC in voxl2?posted in Ask your questions right here!Hello, I am using voxl2. Whenever I connect the battery, the device resets the RTC(Real Time Clock) to 1970-01-01. This is understandable. My issue is that I tried to sync the RTC to UTC using several ways, but I couldn't. Can I know the how to sync the RTC to the UTC?  I tried to use "$ sudo timedatectl set-local-rtc 0", it didn't work. 
  Another approach is using hwclock, but it didn't work either. 
  The last approach is the below command, but I met permission denied, even though I am a root user. 
  How can I RTC to UTC? Thanks, 
 Kay

    How to enable BBR in VOXL2?posted in Ask your questions right here!Hello, I would like to improve the network performance in VOXL2 and I found out about the BBR. - https://blog.apnic.net/2020/01/10/when-to-use-and-not-use-bbr/

 I thought I could use the BBR because VOXL2's OS was ubuntu 18.04 and its kernel version was above 4.9. However, I encountered the error message below. Is there a way to apply the BBR to VOXL2?
