My suggestion is to use 802.11s (load ath10k_core with rawmode=1 - for example add it as parameter for ath10k_core to in the *ath10k file in /etc/modules.d/) instead of adhoc/ibss when using a recent QCA988* firmware. You have to set the mesh_ttl=1 and mesh_fwding=0 when you want to use bmx instead of the 802.11s mesh protocol(s). The wireless configuration could for example look like this: config wifi-iface 'wmesh0' option device 'radio0' option ifname 'mesh0' option network 'mesh' option mode 'mesh' option mesh_id 'myownmesh' # change this option disabled '0' option mcast_rate '18000' option macaddr '02:11:22:33:44:55' # change this option mesh_ttl 1 option mesh_fwding 0 option encryption 'none' But don't expect encryption to work with authsae/wpa_supplicant. I also heard that IBSS should work with the qca6174 (TLV) firmware but I never tested it and therefore cannot confirm it. If you really want IBSS with QCA988x then you have to try the firmware fork of Ben Greear [1]. But it was never really working for me and also still had bugs in AP mode which were only fixed in the official firmware from QCA. Don't forget that you still need the driver patches from Ben Greear.

Re: [OpenWrt-Devel] Ath10k mesh with OpenWRT question
Hi, At some point I was able to get IBSS running with an ath10k radio (QCA988X) using firmware-2.bin_999.999.0.636 [1]. I couldn't test it thoroughly, but it ran for some days in a production BMX6 mesh. I also tried Ben Greear's CT firmware, with no success. If you are starting a network from scratch, however, go for 802.11s instead of IBSS, as Sven said. Kind regards, Roger [1] https://github.com/kvalo/ath10k-firmware/tree/master/QCA988X/main 2015-12-19 10:26 GMT+01:00 Sven Eckelmann: > On Friday 18 December 2015 14:14:38 Zach Sherin wrote: > > I'm trying to use bmx6 to mesh together some routers but keep coming up > > against roadblocks trying to get the wireless chipsets into IBSS mode.

We do see the occasional crash that appears due to CE engine issues. IBSS on CT (and maybe other firmware) doesn't support encryption though, so possibly mesh is still a better idea.
