How can I know BlueZ A2DP, AVRCP profile version.?

How can I know BlueZ A2DP, AVRCP profile version.?

[Chan-Yeol Park]

Dear all

How can I know BlueZ A2DP, AVRCP profile version.?

As far as I search on the web site, A2DP,AVRCP version is 1.0 respectively

But I expect BlueZ version is higher than we search.


Thanks!

For A2DP we support 1.2, or at least that's the spec version I've been  
using when doing the implementation. For AVRCP we've used the latest  
spec. version but since we don't have metadata transfer support yet we  
can only claim 1.0 conformance (the code might actually register a SDP  
record with a higher version so you'll need to modify that if you  
intend to do qualification).

I think that Johan and Luiz can give you more detailed answers here.
However normally BlueZ follows the latest specs., but in the case of
AVRCP I am sure we only implement some of the optional features.

Dear all

Does BlueZ Support A2DP as both Initiator and Acceptor role?

As far as I look-up the code , I could find A2DP as only INIT role. 

However both role are mandatory in A2DP 1.2, I believe BlueZ support both
role. 

If you know this role information, please let me know.

Thanks!

Yes. (after all, they are both mandatory in the spec.)

I'm not sure what code you have been looking at but BlueZ does a  
server AVDTP socket and a mechanism for handling incoming AVDTP  
commands (see audio/avdtp.c for more info).
