Hi !

About half a year ago I created my own infolink emulator and patched some js code on my UE40EH5307 to use my infolink instead of infolink.pavv.co.kr. My emulator writes access logs of all queries made by tv.
Recently I reviewed the logs and found very strange behaviour. At random time every night tv blindly wakes up.
Then I created simple cmd script for addition behaviour study.

Code: Select all

:1
set OK=N
for /f "tokens=*" %%a in ('ping -n 1 192.168.2.3 ^|find "Reply from 192.168.2.3"') do (
set OK=Y
)
if /i %OK% EQU Y (
 echo + %DATE% %TIME%>>tv.log
) else (
 echo - %DATE% %TIME%>>tv.log
)
sleep 10
goto :1

It pings TV every 10 seconds and writes + or - sign to log file with date and time.

here is sample log of this script :

Code: Select all

Log from my infolink emu :

I havent visually noticed TV was up at 04:49.
Why does it wake up every night ? What kind of tasks require OS boot ?

hi,

i think this is because OTN upgrade. If you switch OTN off in service menu, TV shouldn't fill up your logs at night

btw, what emulator do you have? i think ppl are interesting in this more detailed...

Long ago I disabled OTN in service menu. I'll recheck when able - who know if it somehow was reset to default.

I posted it here before under another nick.
You can look at the code if you want: http://www.sendspace.com/file/6127ec

Main purposes :
1) stop undeclinable automatic updates of smarthub and widgets
2) remove dependency of external servers in Korea. They often become unavailable or very slow.
3) Remove forced partner widgets and replace them with user chosen.
4) Remove big-icon widgets such as SocialTV, FamilyStore,...

I run this emu on my openwrt wireless router.

@dec0ding, have you lost your login data (password?)

Actually i don`t know any other reason for nightly wake-ups than OTN upgrade checking. Also delayed instal in menu-help-software upgrade should be off.
