Hi Soumya,

On this topic, here is update from command line:

By using svc and wpa_cli, we can enable & disable WiFi from command line and it works well along with Ethernet enabled. However, WiFi can't keep its IP address after connected to an access point if Ethernet is ON. The IP address on "wlan0" will be dropped between several seconds and 1 minute after it's assigned, on my TI Panda 4430 board.

This shows a stability issue in this mode. For the log from my serial console, please refer to attachment, especially this line:

root@pandaboard:/ # [ 230.582550] cfg80211: Calling CRDA to update world regulatory domain

Because after it shows, the IP address on wlan0 is lost. This is observed on build 479, Android 4.3.1. Since on our latest Android 4.4, WiFi is currently unavailable:

https://bugs.launchpad.net/linaro-android/+bug/1255639

Then we can check this issue again once above bug got fixed.

FYI.

Thanks.

Best Regards Botao Sun

Hi Vishal,

Do you think we need a bug in Launchpad to track this issue?

Thanks.

Hi Botao, I have checked twice the image with panda 4460 board:

1. basically, when eth0 cable is plugged in hw, and wifi is not turned

on from UI, # busybox ifconfig -a not shown the wlan0 only eth0 up and accessing network. 2. when you turn on wifi it will ask you password, after assign password, wifi shown connected (but inactive), # busybox ifconfig -a shown the wlan0 candidate but no inet address, and mask. 3. when unplugged the eth0, wlan0 is get inet address and musk, and connected.

on the other hand wifi is working well, there is no issue with Youtube playback, or enable from UI, after assign Password.

so, both are not up at the same time.

this stuff is observed from since Android version: 4.3

@Botao, what is your opinion ?

Thank You. Best Regards Soumya Basak.

OK, with more tests, the problem is, if no Ethernet cable attached, WiFi works, otherwise, it shows the error I mentioned in previous 2 emails.

Is it a "work-as-design" stuff or a bug? If we keep it likes this, then in order to test WiFi, I have to disable Ethernet first, then restore it after the test is done.

Thanks.

Hi Soumya,

The WiFi doesn't work on 13.10 release image either:

https://android-build.linaro.org/builds/~linaro-android-member-ti/panda-lina...

On my TI Panda 4460 board, same behaviour observed, and following output shows:

Would you double check it on your side? Based on the output of "ifconfig", there is no IP assigned to wlan0 interface:

Hi Soumya,

Please take a look at WiFi status on TI Panda 4460, with Linaro Android build 479:

http://snapshots.linaro.org/android/~linaro-android-member-ti/panda-linaro/4...

http://snapshots.linaro.org/android/~linaro-android-member-ti/panda-linaro/4...

http://snapshots.linaro.org/android/~linaro-android-member-ti/panda-linaro/4...

You can use "wget" to download them in your local terminal if the web page can't be shown up.

I ask because I just found WiFi doesn't work via GUI on my side, following log shows in serial console:

[ 25.692474] wl1271: loaded [ 26.373870] smsc95xx 1-1.1:1.0: eth0: link up, 100Mbps, full-duplex, lpa 0x45E1 [ 27.608551] wl1271: firmware booted (Rev 6.3.0.0.77) [ 27.629058] ADDRCONF(NETDEV_UP): wlan0: link is not ready [ 29.750000] ADDRCONF(NETDEV_CHANGE): wlan0: link becomes ready [ 29.803771] wl1271: Association completed. [ 29.951232] init: sys_prop: permission denied uid:1003 name:service.bootanim.exit [ 30.969970] cfg80211: Calling CRDA to update world regulatory domain

The access point can be shown successfully in the list, and I can click and enter password as well, but then above output shows, with "Disabled" under the access point name on my screen.

Based on our test result spreadsheet, it should at least work on 13.10 release image. I'm going to try it soon.

Thanks.

Best Regards Botao Sun

Hi Soumya,

Let's continue on this topic. I just raised a new bug about this:

https://bugs.launchpad.net/linaro-android/+bug/1267475

On our 13.12 release image, it doesn't work on TI Panda 4430, whatever Ethernet cable attached or not, "Failed to connect to network" message shows.

Would you help to double check it?

@Vishal, do you know the root cause behind those "UNKNOWN COMMAND" message? I ask because the WiFi automation test script is using wpa_cli to conduct the test.

Thank you.

Best Regards Botao Sun

we will validate the issue once the wifi on Panda is up and running.
