Nokia 770 Monitor Mode is working!

just read it on the developer list and tried it right away, and yes it works. So since firmware 51-13 (should be the latest) we have working monitor mode.

Since you need the Linux wireless tools to set monitor mode (iwconfig wlan0 mode monitor) and the 770 comes without them I complied and packed them. Download them here.

NMAP and Bluetooth Keyboard

so I just uploaded a packaged version for the 770 of NMAP. Its a really cool thing to have on the 770. Especially since I now (Dec. 2005) own a cool Bluetooth keyboard (Stowaway Think Outside) which I got as a birthday present from my girl friend. It, together with an xterm console, really makes your 770 more usable. I started installing all the necessary shell utilities and now its just a cooler device. Also the keyboard applet is far from perfect right now. I have problems getting enter/return working sometimes. Also the power save mode kicks in too often.

click to get full size

here is a much nicer screenshot of xkbdbthid I took it using mst. Which is a nice networked screenshot tool. Also it tells you to only bind to 127.0.0.1 (localhost) you can access it from any computer on the network.

xkbd-bthid

...is my latest Bluetooth tool. It's a soft-HID device as I call it. This is a Bluetooth HID Keyboard software implementation. It turns your Linux box, PDA or tablet into a Bluetooth HID Keyboard. This is the same thing some of the newer cellphones have, now we have it for Linux!

This is the very first release, so expect it to be buggy. For example it doesn't support MacOSX by now (because I don't have a Mac) since MacOSX requires a other sub protocol (blablabla).

Check the xkbdbthid site and my Nokia770 page for downloads and instructions.

This is actually just my first HID tool, some more stuff is coming up but I just don't have any time now so I first release this cool thing for you.

Feedback is more then welcome as always!

Happy New Year, here is IpHome 0.2! Actually this was just a test tool but so many people downloaded it and I got some emails with feature request - so I decided to put in more features. Now you can cycle through all interfaces which are up and have a IP address assigned. Just tap the plugin display panel to switch to the next interface.

Download it from my 770 section.

iphome IpHome is a small and simple hildon homepage plugin that shows the current IP and TX/RX bytes and errors. Its meant to be a first try homepage plugin, also I am an information fetishist so I like to know whats going on on the network :-] I also want to keep an eye on the network because of the wireless speed issues.


For those who don't know what hildon is, its the GUI system used by the Nokia 770.

Download is in my Nokia770 section, have fun.

770: wireless speed issues

while playing around in my home network I noticed that wireless is kind of slow, I only have 1.5Mbit DSL so I didn't noticed it before. But now I tried to download stuff from my laptop via FTP and boy this sucks. I did a few tests with different security settings, since I use WPA and WPA is done in software, I though this could be the problem. Here are the results:

setup
    WRT54GS - with wrt-dd #22 prefinal4
    computer running Debian with proftpd (xinetd)
    N770 with Opera as ftp client
tests
    WPA-PSK TKIP+AES
    ftp ~80KB/s (cpu maxed out)

    WPA-PSK TKIP
    ftp ~150KB/s (cpu maxed out)

    WPA-PSK AES
    can't connect

    WEP 104bit
    ftp ~400KB/s (peek ~560KB/s)

    WEP 40bit
    same as for 104bit

    NONE
    same as for WEP

I didn't try WPA-EPA (radius). Also I noticed that the download destination also impacts the speed. When writing to memory I couldn't get more then 160KB/s, so all test downloads were done to MMC.

770: be nice to enjoy

after all the bashing against some of the 770 bugs I again have something nice to say about it. I finally installed FBReader and a bunch of e, pdfs and html-books. Now I use it as a handy reference manual, search ability is so great (let's quick check which RFC xyz was specified in). It's not perfect yet (perfect does not exist...).

To enjoy your 770 even more you need to be really nice and: don't open multiple websites at the same time (most of the sites just have too much junk and make opera eat your memory), be patient if things seem to hang it will recover faster if you don't try to switch apps, open the menu or change back to normal screen. Disabling flash in opera is also a good idea (I don't like it anyway - sometimes only for games).

Also by now I prefer the 770 over my h6315 for listening to podcasts. The 770 doesn't completely freeze when playing mp3s. It now happened multiple times that it suddenly stopped playing, every time I thought damn it it crashed again. But it didn't I only drained the battery to the ground - I guess thats a good sign :-)

eBook Reader

ebook reading really seems to be the killer application for tablets and/or big-screen PDAs (if there is a difference between them besides the lack of PIM tools). InternetTabletTalk [1, 2] amongst many seem to think this way. Also yesterday at a friends birthday party (90% IT workers aka GEEKs) we had a short discussion about PDAs, portable media players and friends. Many of us came to the conclusion that we want a viewing devices. This means mainly: PDFs, HTML and insert popular ebook format here. Everybody complained about their favorite device either the screen is to small or unreadable outside, the device is too slow when rendering content, storage is to limited or DRM sucks to badly. Also what about watching movies on the same device? Na - we don't want that, that just makes the device to multi purpose and that never works out well.

As a comment to Russell's review, I really think Internet access is the killer application for the Nokia 770. All the other features are just add-ons. Of course you need the special viewers (web browser, rss reader, audio streaming client and all the different format readers).

Finally what I would like to know is, if people carry around their 770 during the day (when you are not at home/office)? Are you carrying it around with your cellphone or do you keep it at home close to your couch and fast wifi access? I personal only take it to places where I know wifi is available for me.

770 crashes

a rather sad report about my 770, I apologise to all 770 developers in advance for hurting their feelings (I know how it is like when somebody complains about your software).

The web browser (Opera) continues to crash on me with random sites also sites not always make it crash, its a random thing (digg.com is a good example). I tried to reproduce it but its to random, sorry no decent bug report.

The file manager is slow as hell (with big directories) - I guess this has to do with the pre-fetching which I noticed with obexftp (accessing files on your cellphone). Also I got many very long hangs (no display update or reaction to user input) and crashes, mostly while browsing large directories. The memory usage seems to be pretty insane too.
    I get around using the file manager for browsing large directories by using opera (url=file:///).

Device just rebooted/reseted while playing with WPA-PSK - I really guess it was just a coincidence. This happened while setting up WPA-PSK on my parents Linksys WRT54GS (wrt-gg). I had opera and xterm running and the connectivity-settings panel open. Suddenly the device silently reboots (no low memory waring as usual when you do nasty things with opera). No data lost! Just a normal reboot. I tried to reproduce it again - but no luck. Maybe just some problem with the wireless driver where it dead-locked itself and some kernel watchdog killed and resurrected the device (I was heavily messing with the access point settings). This never happened to me with any Linux box I wasn't messing around in the kernel.

Anyway I still totally like this thing also everybody always comes over to look at it :)

More feedback is on the way... I still need to investigate some of the things I want tell you folks.

Being a 770 user...

when I first got my Nokia770 I started right away with hacking (developing and porting applications) rather then actually using it. I started being just a user over the Thanksgiving weekend. Some user things I noticed where:

We have Flash/Shockwave support, thats kind of nice. I actually didn't expect this. Also web browsing is really nice, just sitting on the couch watching TV and surfing on the tablet. But unfortunately the browser (Opera) is sometimes a little picky and crashes or just eats memory when going to some of my favorite sites.

A PDF reader, yes there is one on the 770. Don't reading the product manual really pays of - if you like surprises :)

Now for some bad things, the email client. I think I remember somebody complaining about the lack of SMTPS (SMTP with SSL) support. Yes, this is unbelievable the email client doesn't support SSL for outgoing mail, why? This makes the mail client totally useless and just a waste of storage space. Maybe the idea behind the email client is a email reader because IMAP supports SSL. Anyway Opera nicely renders my webmail page (IMP/Horde), so it's not to bad.

Some remarks about the filemanager, especially about the OBEX browser (this is the thing that gives you access to the files on your phone). The OBEX part is supper aggressive, it not only gets the current directory information it also goes into subdirectories. If you browse directories with a lot of subdirectories and files, the filemanager sometimes is just blocked totally because of all the pre-fetching.

Also you can't directly use files from OBEX sources, I wanted to play a MP3 from my phone on my 770 but the audio player complains. I thought I could just use the big SD card in my phone as network storage for my 770, but I guess I have to finally finish btfs to get this functionality.

One last thing, I noticed that the wireless antenna (802.11/WiFi) seems to be pretty good for such a small device.
