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 driver ?
Your chip might need some firmware which needs to be downloaded before doing an up on interface ... things like that ... Does openBT has any kernel space components ? or is it just user-space ? regards, Pavan On Wed, Sep 16, 2009 at 2:36 PM, venu <vjosy...@gmail.com> wrote: > Hi Rajesh, > > Bluetooth is not exactly usb/serial driver.
