can u help me with this one? the guide doenst seem so clear... how to compile gctwimax n etc @_@

i heard dat if we abruptly turn off pi it will corrupt the sd card? is it true?
anyone here did a DIY safe shutdown or off button for their pi? please guide n share here. thanks very much

hey guys so i tried use my raspi model B+ and compile the gctwimax as per instruction from this site https://answers.launchpad.net/ubuntu/+sourc...question/195514

however at the end i got an error wen i try use my yes4g dongle n it says Drive /dev/sr0 does not contain audio
so in the end i cant even connect to internet using my yes4g dongle coz of this... if any sifu willing to help me i m really appreciate... thanks in advanced

yup tried all 4 usb ports still same result.... i use an external power pack 10000 mah with 1A 5V output to supply power for the pi... have u any idea y it became like that? i mean wats yes4g dongle have to do with audio files?

thank you sir for ur verdict. do i need to connect the usb n do a reboot and check the log? or just connect the usb once i m in desktop mode?

hello guys just wan update so as u all know i m currently trying to make my raspi work with my yes4g dongle... i been following this link:
http://9m2pju.blogspot.com/2012/07/linux-a...imax-modem.html
but end up in vain... i still result in lots of errors... so after a while i m trying to figure out whats the error behind it and i found out everytime i will have error during this step:
# to make without dbus uncomment the next line remove the CFLAGS option
make CFLAGS=-DWITH_DBUS, or
make
sudo make install

all this time i only copy paste the commands n scripts but i notice i usually stuck here everytime... usually wen i enter command "make CFLAGS=-DWITH_DBUS" it will show some sort of error... and in the end i just go ahead n put make and then sudo make install... plus it also said in the link "# to make without dbus uncomment the next line remove the CFLAGS option" wat does this means? do i need to edit script or some sort? uncomment some lines in script? pls help me with this project sifus!

hey guys currently i m working on a profject for portable 4g broadband modem out of raspi. currently work in progress... added on shutdown reset buttons... also add a wifi adapter as an access point... planning to 3d print casing for this...

yea mix of here n ter instructions across google
btw i noticed dat wenever i try to run the pi without hdmi pluged in it wont start properly n the wifi dongle that i install doesnt start up too. any1 can help with this? how can i make the pi run as usual without hdmi thingy? since i wan make a portable router it wont be practical if i need to plug in hdmi dosplay everytime i need to use it? any help much appreciate

weird thing is wen i plugges in hdmi n turn it on it will work perfectly fine. but wen i m not using hdmi n turn it on i can see the yellow n red flashing n it seems like its booting but after a while it will just lights up red... n even the blue led from my wifi dongle doesnt lights up too...

hey guys so here a bit update that i wan share with u guys abt my raspi broadband router project... as some of u guys ady noe i was planning to make a portable ones using my powerbank but unfortunately ters an issue regarding the PSU adapter n etc and eventually i can only make it work only by plugging in hdmi... so i decided to change my plan and use a dc adapter off from the wall in mean time hoping i could figure out way to make this thing portable. so here a pic of quick n dirty diy of my raspi broadband router up and running...

its a 10,000 mah powerbank with an output of 5v 2A...

I actually use the same cable now n it works fine so cable shldnt be a problem... ters a dude told me dat the hdmi cable help to earth the freq from the power bank so dats y it only function well if i hav hdmi cable plugged in...

Dongle can use d-link dwa 123 11n... i use it n works great only dat u need to install driver 1st...

hey guys so i finally fin my raspi router project that i been doin for past few weeks. so here some pics...


maybe later in future i might sand a bit the casing so it looks nicer. btw rep for altan for providing 3d print service
btw i was planning to add few of leds so that it indicates that the internet connection is available... i read a few articles here n ter n found out that i could add led to the gpio pins but that requires some serious coding n scripts... i m just a student n not even in IT nor programming
so if any sifus here could share their knowledge related to this? thx very much!

well then mind share it here?

currently i use script that would check if it could ping internet connection every 2 mins... if it couldnt ping the connection means the service is down n it will reboot... so i was thinking if ter could be a script that could light up led wen the pi could ping the internet connection... so i think it would be great way to indicate if the connection is OK or not.... sorry for the noob explanation lolz

so heres wat i found from net:

sudo mkdir /opt/check_lan
sudo nano /opt/check_lan.sh

Then enter the follow bash script:

#!/bin/sh

# cron script for checking wlan connectivity
# change xxx to whatever IP you want to check.
IP_FOR_TEST="xxx"
PING_COUNT=1

PING="/bin/ping"
IFUP="/sbin/ifup"
IFDOWN="/sbin/ifdown --force"

INTERFACE="wimax0"

FFLAG="/opt/check_lan/stuck.fflg"

# ping test
$PING -c $PING_COUNT $IP_FOR_TEST > /dev/null 2> /dev/null
if [ $? -ge 1 ]
then
logger "$INTERFACE seems to be down, trying to bring it up..."
if [ -e $FFLAG ]
then
logger "$INTERFACE is still down, REBOOT to recover ..."
rm -f $FFLAG 2>/dev/null
sudo reboot
else
touch $FFLAG
logger $(sudo $IFDOWN $INTERFACE)
sleep 10
logger $(sudo $IFUP $INTERFACE)
fi
else
# logger "$INTERFACE is up"
rm -f $FFLAG 2>/dev/null
fi



Then in a cron job you can run this script every 2 minutes.
sudo nano /etc/crontab and enter the following at the bottom

*/2 * * * * root /opt/check_lan/lan.sh >/dev/null

thanks for ur verdict sifu... i have no basics in programming n codings so to build a scripts like dat would be very unlikely. so far i only copy n paste from the net only
