Overview

Bug Labs released an updated file system for the BugLabs Y.T. on May 31st 2011. This file system release included upgrading to Linux Kernel version 2.6.35, as well as a number of updates to modules/tools, and projects, which is detailed in the R2.1.0 changelog.

Errata

Connman network connections: Connman can sometimes fail to connect to a base station on the first attempt, when running test-connman connect <network_id>. This can be worked around by doing multiple calls to connect. Very rarely, connection will still not work after the 3rd attempt. In those cases connman should be restarted, by running /etc/init.d/connman restart, waiting 60 seconds, then running test-connman connect <network_id> again.

Wireless does not connect on boot with the Stinger: When booting with the stinger without ethernet and power plugged in, wireless does not autoconnect. This is due to a conflict between connman and other apps, where eth0 is automatically given an IP address even if no ethernet cable is available. In that case connman mistakenly assumes eth0 is running OK, and does not connect. To work around this: boot with the power off. Then plug it in once wireless is connected, or use /usr/lib/connman/test-connman restart to restart connman.

Ad-hoc wireless mode is not supported in the networking GUI: Well, no excuses for this one, and no simple work-around. We can't do everything perfectly the first time, even though we try.

Monitor looks bad/strange/small: We now set monitor setting based on the EDID information that the monitor self-reports. Some old monitors return broken EDID strings, or sometimes xorg server does not like valid settings that should work. This may result in the video driver choosing a lower setting, and in rare cases float in the upper left or right corner. If completely corrupt EDID data is returned, the display will default to 1024x768. Workaround for this (small) family of problems are available on their own wiki page.

Networking GUI App is hard to enter info on: Unless dragged carefully, the Networking GUI can be a pain to use. We recommend you click the show password button before entering the access point passphrase. When you click in the passphrase entry field, the on screen keyboard will come up. Scroll down to see the passphrase entry field (by using the scroll bar in the upper right hand side of the screen, under the close window X). We are working on some new GUI solutions, but for now you're going to have to scroll a little bit.

USB -> RS232 driver for PL2303 not available: If you try to use a PL2303 USB to Serial (aka RS232) converter device, we did not include the drivers for them. We recommend the FTDI USB to Serial converter since they are a bit better. Contact us via email, if you really, really need to use a PL2303 device.

Plugging the stinger into a running bug might reboot it: Due to a minor powersystem bug, plugging a Bug Stinger into a BugBase TY may rboot the BugBase for some individual bases. This is a known issue to be fixed in further hardware revisions.
