You can make use of the wl127x-rfkill reference driver that comes along with android kernel (not vanilla). Check out drivers/misc/wl127x-rfkill.c - This is a little driver that exposes the GPIO via an rfkill interface. So, to drive high the BT_EN gpio (say GPIO number 100) - You need to have platform data into the wl127x-rfkill to have nshut_down as 100. Upon probe, you can toggle the gpio from user-space via echo 1 > /sys/class/rfkill/rfkill0/state. > How can i do that? > Regards, > Parth > > On Mon, Sep 19, 2011 at 7:24 PM, Pavan Savoy <pavan.sa...@gmail.com> wrote: >> >> On Mon, Sep 19, 2011 at 7:50 PM, parth shah <parthmshah2...@gmail.com> >> wrote: >> > Hello Friends, >> > >> > I have 3 UART on my board. i'm usinf UART2 for Bluetooth. >> > >> > How can i mapped that UART to Bluez stack so that i can run hciattach >> > commad? >> >> hciattach takes command line arguments for the UART in use, like >> hciattach /dev/ttyS1 => if UART2. >> >> > Also which driver does BT UART use in general? >> >> Also depends on the manufacturer argument for the hciattach, If no >> specific arg and "any" is used, hci_h4.c working along with hci_ldisc >> is used (drivers/bluetooth/ directory). >> >> > >> > Regards, >> > Parth >> > >> > -- >> > unsubscribe: android-kernel+unsubscr...@googlegroups.com >> > website: http://groups.google.com/group/android-kernel >> >> >> >> -- >> --Pavan Savoy >> >> -- >> unsubscribe: android-kernel+unsubscr...@googlegroups.com >> website: http://groups.google.com/group/android-kernel > > -- > unsubscribe: android-kernel+unsubscr...@googlegroups.com > website: http://groups.google.com/group/android-kernel -- --Pavan Savoy -- unsubscribe: android-kernel+unsubscr...@googlegroups.com website: http://groups.google.com/group/android-kernel
