Does Omega2 wireless chip support 802.11s mode?
-
I'd like to know if Omega2 supports 802.11s wireless mode for building mesh applications. What wireless driver does it use and what is
iw dev
command output on OpenWrt?

I have no experience with the WarpCore driver, which is the (proprietary) driver the official Onion FW uses.
But if you use vanilla OpenWrt on the Omega2, the driver is
mt76
which definitely does support 802.11s.What I don’t know, because I have little WiFi knowledge, is wether the MT7866 SoC has the needed HW to allow
mt76
to support 802.11s.But I can provide
iw dev
on a Omega2 running Wifi withmt76
:# iw dev phy#0 Interface wlan0 ifindex 4 wdev 0x2 addr 40:a3:6b:c1:XX:XX ssid XXXXXXX type AP channel 11 (2462 MHz), width: 20 MHz, center1: 2462 MHz txpower 13.00 dBm multicast TXQ: qsz-byt qsz-pkt flows drops marks overlmt hashcol tx-bytes tx-packets 0 0 1009 0 0 0 4 377291 1109
Does not look overly telling to me. But experimenting a bit with what
iw
has to offer I'd guessiw phy
could be more interesting, especially the "mesh point" mode listing# iw phy Wiphy phy0 max # scan SSIDs: 4 max scan IEs length: 2257 bytes max # sched scan SSIDs: 0 max # match sets: 0 max # scan plans: 1 max scan plan interval: -1 max scan plan iterations: 0 Retry short limit: 7 Retry long limit: 4 Coverage class: 0 (up to 0m) Available Antennas: TX 0x1 RX 0x1 Configured Antennas: TX 0x1 RX 0x1 Supported interface modes: * IBSS * managed * AP * AP/VLAN * monitor * mesh point Band 1: Capabilities: 0x17e HT20/HT40 SM Power Save disabled RX Greenfield RX HT20 SGI RX HT40 SGI RX STBC 1-stream Max AMSDU length: 3839 bytes No DSSS/CCK HT40 Maximum RX AMPDU length 65535 bytes (exponent: 0x003) Minimum RX AMPDU time spacing: 4 usec (0x05) HT TX/RX MCS rate indexes supported: 0-7 Frequencies: * 2412 MHz [1] (13.0 dBm) * 2417 MHz [2] (13.0 dBm) * 2422 MHz [3] (13.0 dBm) * 2427 MHz [4] (13.0 dBm) * 2432 MHz [5] (13.0 dBm) * 2437 MHz [6] (13.0 dBm) * 2442 MHz [7] (13.0 dBm) * 2447 MHz [8] (13.0 dBm) * 2452 MHz [9] (13.0 dBm) * 2457 MHz [10] (13.0 dBm) * 2462 MHz [11] (13.0 dBm) * 2467 MHz [12] (13.0 dBm) (no IR) * 2472 MHz [13] (13.0 dBm) (no IR) * 2484 MHz [14] (13.0 dBm) (no IR) valid interface combinations: * #{ IBSS } <= 1, #{ managed, AP, mesh point } <= 4, total <= 4, #channels <= 1, STA/AP BI must match HT Capability overrides: * MCS: ff ff ff ff ff ff ff ff ff ff * maximum A-MSDU length * supported channel width * short GI for 40 MHz * max A-MPDU length exponent * min MPDU start spacing Supported extended features: * [ RRM ]: RRM * [ CQM_RSSI_LIST ]: multiple CQM_RSSI_THOLD records * [ CONTROL_PORT_OVER_NL80211 ]: control port over nl80211 * [ TXQS ]: FQ-CoDel-enabled intermediate TXQs

Thank you! Yeah, it looks like it supports 802.11s peering. If it works in practice, that's awesome.
