Issues Setting Up Ad-Hoc Network with Orin Nanos Jetpack 6.0 - BSSID Mismatch

Hi everyone,

I’m setting up an ad-hoc (IBSS mode) network between two Orin Nanos to send UDP packets between them. I’m using iw to set up the network, and while both devices are up and running with the same SSID (AdhocTest), the BSSIDs are different.

I’ve manually assigned static IPs to both devices, and I’ve checked with iw dev wlan0 info and iw dev wlan0 link, everything seems fine except for the BSSID mismatch.

Has anyone encountered this issue or knows how to resolve it?

Thanks!

Hi,
Please share how to set up developer kits to replicate the issue. So that we can check further.

Sure! I upgraded to a fresh copy of JetPack 6, did sudo apt-get update and upgrade. At this point everything should be up to date. Then I typed in the following commands in terminal on both devices:

  1. sudo ip link set wlan0 up (it was already up, this is just to make sure wlan0 is turned on)
  2. sudo iw wlan0 set type ibss
  3. sudo iw wlan0 ibss join “AdhocTest” 2462
  4. sudo ip addr add 192.168.1.1/24 dev wlan0

At this point, iw info looked correct on both devices. Then, to make sure the hardware MAC address is correctly resolved, I ran sudo arp -s 192.168.1.x [MAC address] on both devices. ip routing is also showing the correct route. However, neither devices can connect to each other.

Hi,
Please try this to set static IP and see if it works:

Q: How to set up static IP address?

And do yo connect the two Jetson Nano developer kits to LAN via Ethernet? Or two devices are directly connected through a RJ45 cable?

I will try this tomorrow. I want all devices to be connected via wlan, so I’m not using wired connection at the moment.
