Re: shared hci transport

Hi Pavan,

A lot of recent BT chips intefaced by UART also tend to have another radio [mostly FM] on the same chip sharing the transport interface i.e the UART. [bcm4325 for example has bt, fm and wlan].

I just wanted to know, from the user-space the hci0 socket interface allows me to concurrently use the uart from several applications, but
is there a way in kernel to do the same ?

[say hci_h4 is also used by the fm core to understand some vendor specific commands ?]
or in an usb case - the fm has int endpoint for control data of fm [+ hci-event/cmd packets] and bulk for rds[+ acl] [assuming the audio data path - is isolated from all these ...]

this all depends on the actual transports. I would need the
specifications to tell you more on the right way to deal with it.

Regards

Marcel
