    If you run "Upgrade Pandora OS" now you'll get a somewhat significant kernel update to 3.2.57. Main thing is improved powersaving while lid is closed, but also there is updated wifi driver. As bad as the internal wifi is, it can do monitor mode and packet injection, I've tested it with Kismet (can package it for the repo if anyone needs it) and it seems to work well. I've also fixed ad-hoc mode along the way and was able to network 2 pandoras without an access point. Note that power saving won't work in both monitor and ad-hoc modes, so it'll drain the battery pretty fast.

    It's a bit experimental, there were many changes so it would be nice if everyone tested things they usually use and reported back if something is wrong.

    Here is the changelog:

    Forgot to say this stuff needs some testing as there were quite a lot of changes (first post now updated). So go forth and test!

    Indeed!  One of the reasons I love the Pandora more :) (still actively being supported!)

    Thank you! I know you say that the added 10-20% power saving is only while the system is idle, but does it help at all with the lid closed and minimal CPU usage, such as playing an MP3?

    hmm.. I could not upgrade because I have a 17Mb .thumbnails folder on my internal card. This reminds me of my Debian, where I had like 5GB of cached images.

    This is save to run:


    find ~/.thumbnails -name '*.png' |xargs -I{} rm {}

    Also symlinked it to an SD card.

    will tinker now with the new config.

    It means the Pandora can now play audio that only serious audiophiles can tell is better.

    Well, it certainly hasn't fixed the Wifi at all - I'm downloading with PNDManager at 64Kb/sec on my 10Mb connection, and nothing else in the house can use the Wifi while the Pandora is downloading as it takes all the bandwidth.

    So no noticeable changes here.

    It's not a wifi fix, it's a wifi feature add.

    ZXDunny: hasn't fixed your wifi ;)

    Mine is still good.. Although I do get crazy speeds from the repo sometimes.. All over the place.. But generally it's pretty good

    Since the case on mine was changed it now gets stable 500-700 kb/s speeds.


    Don't know what changed but it is really enjoyable to update stuff from the repo now.

    That is awesome! The power save mode will really help me! Thanks for continuing to update the Pandora even after the announcement of the Pyra :) I am happy the updates will keep on coming.

    Nice power saving!

    My 1GHz unit now consumes only ~80mW with the lid closed, while it used to be ~110mW, an improvement of ~27%. That means its standby time goes from ~6 days to ~8days!

    On my ReBirth unit the difference is much less noticeable. It goes from ~94mW to ~85mW, an improvement of ~10%. Its standby time goes from ~7 days to ~7.5 days.

    Both of my units have the power led disabled.
