Rajesh,
Isn't BT driver eventually a USB/serial driver ? and Wifi eventually a
SPI/mmc driver ?
So all that logic of power management still applies, However there
would be some specific chip specific power management options, which
is very specific to the BT/Wifi chip you use and modify your driv
Pavan,
Yes, I agree with your statement.
But I don't see any WiFi or BT doesn't work with android ! , The same
driver works with linux based UI not with android UI !
Can u name few issues which comes when integrating Android UI with linux
device drivers?
Best Regards,
Rajesh

Hi,
I can comment on the BT part and a bit about Wifi part.
For BT - You should have a BlueZ driver for your BT device, be it usb
or uart transport, it should work with BlueZ in general first. If that
is taken care, then android UI will work out of the box without
any[minimal] issues.
Please spe
Pavan,
We r using CSR based WiFi and BT , where WiFi is interfaced through SDIO
and BT through UART.
Thanks for the info on BT , I am not sure if it is a OpenBT stack BlueZ
stack , One more question do linux kernel downloaded from
www.kernel.orgcomes with OpenBT or Bluez?
From ur below word
Hi Rajesh,
Bluetooth is not exactly usb/serial driver. It depends on kind of bluetooth
support you have. If it is an usb (which usually is the case) then it is usb
driver , but it is an in built module, then it is dependent what interface
the module uses. It can be serial interface or spi or any o
Rajesh,
Linux -2.6.xx comes with BlueZ [current version is BlueZ4.x .. not
sure if kernel bluez also has a version...]
wifi.c modifications because something like an sdio driver might have
to insmod-ed before doing a DRIVER_START ? or the DRIVER_START in
itself might not be supported from your dr
HI,
I think Bluez is a official Blue tooth stack from kernel.org, If it is the
case then it should work without any issues, just now I checked for Bluez ,
it is official which mean default all kernels downloaded from
kernel.orgwill come with bluez , so why there is a chaos in
compatibility when i
Can you specify the problem that you currently having ?
Do you see a "hci0" socket interface created once you do a BT on ?
what does your init.rc file read ? about the service hciattach ?
what does your hciconfig -a say ? does it read the right version
information from the chip ?
regards,
Pavan

For WLAN, the drivers for several chipsets are included in Android,
including chips from TI, Broadcom, and CSR. The TI driver is used on
the ADP1, and the Broadcom driver is used in the Samsung i7500
(Galaxy.). For Android 1.0 and Cupcake, there were some hardcoded
assumptions in the Framework and
