We have several RPC/RSLA4AGX64-B102S-20 Orin AGX devices flashed with jetpack 6.1 that came with Quectel RM520N-GL modems installed (firmware RM520NGLAAR01A08M4G_01.204.01.204).
Here are some issues we are facing:
Slow ping compared to previous hardware version (TX2):
When we attempted to deploy our stack to the Orin while it was on LTE (which we need to be able to accomplish), we would lose our local ping to our wireguard, and the deploy would hang and never complete.
The resolution we found was to lower the MTUs from 1500 to 1300 in our /etc/docker/daemon.json file, our .yml file, and in the wireguard config file.
With these changes we were able to deploy while the orin was on LTE. This change also resolved being able to run a chat feature in our UI.
However, now our pings while a machine is on LTE are so much slower and we are sacrificing timing in communication with the machines.
Our next issue is:
Unable to access the internet using the hotspot connection:
In the same line of LTE/modem issues, we have the Orin’s connected over LTE. We use a t-mobile SIM card and have tested the cards on other devices and experienced no issues.
When I connect my phone (or any other client device) to the hotspots hosted on the Orin/ LTE and attempt to go to any internet site- such as google - nothing happens. However we are able to ping (http://www.google.com/) or 8.8.8.8 from the Orin.
We have tried adjusting our iptables with no luck so far. We haven’t found anything on the forums yet. Wondering if you might have any suggestions?
