Wi-Fi Standards around Roaming

Does Jetson TX2 support 802.11k?

Acordding to Wireless compliance guide (https://developer.nvidia.com/embedded/dlc/Jetson-TX1-OEM-Wireless-Compliance-Guide), Jetson TX2 has Broadcom BCM4354(Cypress CYW4354) Chip and the chip supports 802.11k for fast roaming, but I’m not sure Jetson TX2 supports 802.11k.

Where can I verify this?

No, only 802.11a/b/g/n/ac are supported, you can find the info in module datasheet. http://developer.nvidia.com/embedded/dlc/jetson-tx2-series-modules-data-sheet

802.a/b/g/n/ac is shown in “radio type”, but 802.11k standard is not for radio type (physical topic) but radio resource management(software? topic). Many datasheet have no entry about 802.11 standards except radio type such as 802.11a/b/g/n/ac/ax, then doesn’t the machine support 802.11k really?

Thanks for the note, let me check with internal team for this. Will update once available.

Hi shntar, 802.11k is supported.

Thanks for the comment. Then 802.11k is enabled by default?
(Is the function supported on only hardware or hardware and software, this question is suitable only in the latter case)

I still have trouble with roaming between APs, next I’ll ask to AP vendor (they formerly said to check the device supporting 11k).

The wifi driver on BCM4354 supports the 802.11k protocols, i think maybe you can check with Broadcom first for deeper questions of chip/sw, the official answer will have no doubt.
