Linux: WL1835MOD

Other Parts Discussed in Thread: WL1837MOD

Tool/software: Linux

I have issues with building a 802.11s mesh network with Beaglebone Black Wireless. It is a proof of concept for an operational device where we want to use the WL1837MOD.

I read the document: swaa166.pdf - WiLink™ 8 WLAN Software - 802.11s Mesh . But when I beuild it with Yocto or with the descriptions of TI with build-utilities if have issues.

One of the issues is the wpa_supplicant.conf with mode=5. He doesn't recognize mode 5.

When I look more close to wpa_supplicant defconfig. I have the impression that is not made for 802.11s mesh but rather for the P2P type of mesh. I see in the defconfig no CONFIG_SAE for instance.

Does anybody know how to build wpa_supplicant for 802.11s mesh?

Thanks.
Paul Becue.

    Hi,

    Is your wpa-supplicnat built with the following in it's .config?

    CONFIG_MESH=y
    CONFIG_SAE=y

    If not, then please enable it and rebuild.

    BR,

    This is in my defconfig:
    # 80211s mesh
    CONFIG_MESH=y
    CONFIG_80211_COMMON=y

    and
    CONFIG_SAE is automatically added by the Makefile:
    wpa_supplicant/Makefile:
    ifdef CONFIG_MESH
    NEED_80211_COMMON=y
    NEED_SHA256=y
    NEED_AES_SIV=y
    NEED_AES_OMAC1=y
    NEED_AES_CTR=y
    CONFIG_SAE=y
    CONFIG_AP=y
    CFLAGS += -DCONFIG_MESH
    OBJS += mesh.o
    OBJS += mesh_mpm.o
    OBJS += mesh_rsn.o
    endif

    and the repo ref is:
    R8.7_SP3-devel-ti+gitAUTOINC+ee8fbdb840-r9b
    with:
    # Tag: R8.7_SP3
    SRCREV = "ee8fbdb840d95e048f58fb62bf3b5472041b5417"
    BRANCH = "upstream_25_rebase"
    repo:
    git://git.ti.com/wilink8-wlan/hostap.git;protocol=git;branch=${BRANCH}
    This is the build I used in Yocto for my wpa_supplicant build.

    Thx
