Wrote a quick & dirty python wrapper for the bluez-utils bccmd command to set a the btaddr of an bluetooth hci device. The native bccmd syntax is awkward, so that i found it handy to have a script which accepts normal formated btaddr as an argument and does some error checking and status infomation.

Usage:

root@linux:~/devel/tech/bluetooth/# ./setbtaddr hci0 01:0E:07:75:B7:12
Exec './bccmd  -d hci0 psset -r bdaddr 0x75 0x00 0x12 0xB7 0x07 0x00 0x0E 0x01'
hci0:   Type: USB
        BD Address: 01:0E:07:75:B7:12 ACL MTU: 192:8 SCO MTU: 64:8
        UP RUNNING
        RX bytes:86 acl:0 sco:0 events:9 errors:0
        TX bytes:33 acl:0 sco:0 commands:9 errors:0

Made my very own openwii version including debug routines. So i added a another status led to the chiip design and also added IO lines to the ATmega SIO pins. So now i have a drive chip which prints debug info via a serial line. So everybody who want to understand the dvd drive patching can watch this in serial console. The debug code retrieves the media status flag and prints some other status flags.

Since the 23c3 every interested researcher knew that is easy to compromise bluetooth sessions using the BTcrack tool.Thierry Zoller showed how it’s possible to retrieve link keys, The only problem was to get hands on a bluetooth sniffer device to get the raw bluetooth packets. Such devices are not available at consumer prices. But somehow Max Moser found a way to tranform a vanilla usb bt dongle into a bluetooth sniffer device. Don’t believe the hype…Now bluetooth security is dead.

Mini Howto:

#Backup old firmware
dfutool -d hci0 archiv backup.dfu
# Backup config
bccmd -d hci0 pslist -s 0x000F >> backup_cfg
# Check Vendor ID ( has to be 0x0a12)
bccmd -d hci0 psget -s 0x000f 0x02be
# Write new Product ID
bccmd -d hci0 psset -s 0x0002 0x02bf 0x0002

Wow cool stuff, a podcast playing only real awesome SID stuff, including some newer SID stuff from the last few years. No lamers talking inbetween just chiptunes. Great ! Check it out 8bit Mayhem

BTW my favorite tunes:

Maybe i should code a PSP based SID compilation demo…
