Re: [Bluez-devel] [PATCH] Updated sco flow control feature

[Fabien Chevalier <fabchevalier@free.fr>]

Hello Jose,

The documents i used as reference are the ones from bluetooth SIG. I 
don't know who copied the others, but they are closely similar to the 
one from IEEE :-)
Concerning SCO flow control over UART link, it is stated nowhere it is 
mandatory nor optionnal. :-(

However, having a look at the Bluetooth 2.0+EDR spec (available on 
www.bluetooth.com), section 6.26 "Supported commands" describes the 
bitmask that lists the supported hci commands for a given 
implementation, stating that *It is implied that if a command is listed 
as supported, the feature underlying that command is also supported.*

And guess what ?.... in the bitmask there is a bit for the "Write 
Synchronous flow control enable" command. ;-)

*** cut here ***
    0 Read Hold Mode Activity
    1 Write Hold Mode Activity
    2 Read Transmit Power Level
    3 Read Synchronous Flow Control Enable
10
    4 Write Synchronous Flow Control Enable
    5 Set Host Controller To Host Flow Control
    6 Host Buffer Size
    7 Host Number Of Completed Packets
*** cut here ***

Having analysed all these informations, my guess is that it is 
synchronous flow control is 'optionnal', even for uart links.

Cheers,

Fabien
