according to the ifixit teardown, at least on the first production run it looks like they used a Jorjin WG7310 WLAN controller that also includes BT and FM. it appears they simply left out the antenna and now that we have source, has anyone looked at how difficult it would be to cook in BT and FM support, assuming we install our own antennas?

How do you know that they left out the antennas?

well the antennas would have had to be detailed on the FCC filing and they were not. I can't imagine why they would pay extra to engineers to design in antenna routing for features they were never planning on using anyways. Then the cost of having the antennas put in the hardware would also be unnecessary......im fairly certain they were trying to cut every dollar out of it when possible, but i dont know for sure yet

The Nook Color has a similar chip and no antenna but Bluetooth still functions though with a range of only few feet. I don't know the correct physics terminology, but I believe the chip and the system board act as a primitive antenna. Of course, if the BT functionality operates through separate pins on that chip than the wifi then BT will only work if those data and power pins are properly connected into the system too.

heres something i just noticed.. in the init.rc it has this:

# do not launch the Radio Interface Layer daemon (RILd) service
# since there is NO modem on the board

#service ril-daemon /system/bin/rild
# socket rild stream 660 root radio
# socket rild-debug stream 660 radio system
# user root
# group radio cache inet misc audio sdcard_rw

but, then it has this:

service bluetoothd /system/bin/bluetoothd -n
socket bluetooth stream 660 bluetooth bluetooth
socket dbus_bluetooth stream 660 bluetooth bluetooth
# init.rc does not yet support applying capabilities, so run as root and
# let bluetoothd drop uid to bluetooth with the right linux capabilities
group bluetooth net_bt_admin misc
disabled

so it seems that it could support bluetooth.. i installed the bluetoothd binary, but in logcat at boot it says:

BluetoothHeadset( 1394): Could not bind to Bluetooth Headset Service
ActivityManager( 1394): Unable to start service Intent { act=android.bluetooth.IBluetoothHeadset }: not found

so im guessing the next thing is to mod the services.jar to include bt services?

just checking on the thread, if it has the hardware you would think this would be a big deal

the 2nd chip in the wifi module is the same as the WiFi/BT front end chip in the Nook Color. This is antenna switch, combining both the BT and WiFi connections to use only one antenna. See here and here and here.

If the BT portion is hooked up to a UART on the OMAP, and the BT power enable is wired or connected in tandem with the WiFi power, then BT should be possible.

It appears that the Bluez packages are missing. In the init.ompa4430.rc, this line is disabled:
#Permissions for Bluetooth
# chown bluetooth bluetooth ro.bt.bdaddr_path

but...
the following lines are enabled (this may be for WiFi and not BT):
#change permisisons for radio
chmod 0660 /dev/ttyS0
chown radio radio /dev/ttyS0
