Can, you provide details of the Kernel, TI SDK and host processor being used?

Thanks

Hi,

Hi ,
Are you able to run following commands ?

cd /usr/share/wl18xx
./ap_start.sh

Hi,

I found my conf file in system/etc/wifi

Here, I run the script after on the wifi.

I got some message in screen the "wifi connected true"

I got some warning when execute dhcpd.conf through the ap_start.sh

And one more thing i got firmware error when i changed anything in hostapd.conf file after reboot.

And also i was not configured added wps in the hostapd config.

I have the doubt.

Actually, default ctl_interface is "var/run/hostapd"

But, i fount hostapd in "data/misc/wifi"

May i replace this path to default path.

And always, interface is "wlan1" and ctrl_interface is "wlan0" when i change this and reboot i got error.

Why i am asking this, i want to configure the hostapd.conf file for start the script.

Thanks,

VinothS.

Hi,

Log after run the script. wlan0 was enabled. But, i dhcp not executed.

Thanks & Regards,
VinothS,

Hi ,
You are running a very old version of WiLink8 driver . I suggest you update to R8.7_SP1 : processors.wiki.ti.com/.../WL18xx_System_Build_Scripts

check ap_start.sh script and see if udhcpd path is set ok . After running the script you should see wlan1 interface created

Hi

We are running Android Marshmallow in i.MX6 with WL1831MOD chipset where Wi-Fi device as well as hotspot works, but sometimes we are getting below error and then it never works - strange thing we observed is if we reflash it works and once below error occurs it never works again till reflash. Please help

We followed below link and got it working earlier

Thanks

HI after booting the board enable the hotspot.

Check the folder : data/misc/wifi/hostapd.conf. If it present check the parameters.

If it not present you have to check hostapd/Android.mk

L_CFLAGS += -DCONFIG_CTRL_IFACE_CLIENT_DIR=\"/data/misc/wifi/sockets\"
L_CFLAGS += -DCONFIG_CTRL_IFACE_DIR=\"/data/misc/wifi/hostapd\"

 

If it problem same problem came you have to check data/misc/wifi/hostapd.conf this folder

VinothS

Thanks Vinoth for the Quickest reply.

BTW we are not sure about the scenario of the error, wifi works in the board and after sometime or some number of reboots - it suddenly starts throwing this issue and then onwards it wont work until reflash

I have below piece of code in the Android.mk and hostapd.conf is available in the board once i start the hotspot
# Use Android specific directory for control interface sockets
L_CFLAGS += -DCONFIG_CTRL_IFACE_CLIENT_DIR=\"/data/misc/wifi/sockets\"
L_CFLAGS += -DCONFIG_CTRL_IFACE_DIR=\"/data/system/hostapd\"

One more point i would like to give is, during non working time (not just hotspot) both hotspot as well Wi-Fi Device also fails

hostapd.conf

root@sabresd_6dq:/ # cat /data/misc/wifi/hostapd.conf
interface=wlan0
driver=nl80211
ctrl_interface=/data/misc/wifi/hostapd
ssid=MX6AP
channel=6
ieee80211n=1
hw_mode=g
ignore_broadcast_ssid=0
wowlan_triggers=any
wpa=2
rsn_pairwise=CCMP
wpa_psk=7ad5cf9ac0340176235463e9500366a4182ff2083ec091aa89596f7669846220
root@sabresd_6dq:/ #

and below error keeps coming once error scenario occurs

wlcore: firmware chunk too long: 1702126383
wlcore: firmware chunk too long: 1702126383
wlcore: firmware chunk too long: 1702126383

Hi,

please check this is valid directory or not.

L_CFLAGS += -DCONFIG_CTRL_IFACE_DIR=\"/data/system/hostapd\"

hostapd  not present in this directory data/system/hostapd

So, you have to give the path like that for enable the hostapd

L_CFLAGS += -DCONFIG_CTRL_IFACE_DIR=\"/data/misc/wifi/hostapd\"

Hi Manoj,

I got this type of error in many time and many situation.
Follow my step to fix this to run this command.

"Hostapd -B data/misc/wifi/hostapd.conf"

If error is come the problem is hostapd.conf file.
You will better notice some simple parameter also.
If you are giving same after like that also it;s gives same error(ex: wowlan_triggers=any).

Check your source code also for hotspot.
"system/netd/server/Softapcontroller.cpp"
