@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.

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

@Moderator Oh, thank you so much for sharing it. I'll check it!

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/
• https://www.linuxbabe.com/ubuntu/enable-google-tcp-bbr-ubuntu

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?
