Part Number: WL1831MOD
Other Parts Discussed in Thread: WL1831, WL1835

Hello,

           I am trying to configure wilink WL1831 IC with imx6 processor.

My wifi is working properly but bluetooth is not working.

I have set kim, uart and btwilink in device tree of linux 3.14.28 and apply the ti patches.

when I run hciconfig hci0 up command I get below logs ---

Please guide me how can I solve this problem --

    Please, make sure you are using the correct UART/tty port. In addition to the instructions at 'http://processors.wiki.ti.com/index.php/WL18xx_First_Time_Getting_Started_Guide_(IMX6)',

    TI WL18xx related patches applied in kernel and file system related artifice build in file system.

    /lib/firmware/ having TIInit11.8.32.bts file
    /lib/firmware/ti-connectivity having wl1271-nvs.bin wl18xx-conf.bin wl18xx-fw-4.bin

    /usr/sbin/wlconf/ and /usr/sbin/wlconf/official_inis files are proper

    /dev/hci_tty and /dev/ttymxc4 nodes are present

    cat /proc/kernel/debug/gpio shown kim with gpio1_IO10.

    Any thing I am missing, please guide.
