Subject: shared hci transport
Date: Wed, 26 Aug 2009 17:06:24 +0530 (IST) [thread overview]
Message-ID: <639511.66794.qm@web94914.mail.in2.yahoo.com> (raw)
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 ...]
regards,
Pavan
