what is a Bluetooth profile?

[jeff4yee]

specificly, A2DP profile?

can it be implemented in J2ME and installed into symbian s60?

No, this cannot be done from within J2ME.

hi,
thanks for replying.
why is it cannot be done in J2ME?
any proof for your statement?

[traud]

was incorrect

Sorry, I stand corrected.

The A2DP Bluetooth profile is not based on eSCO but ACL (data) Bluetooth links and therefore based on L2CAP connections. If your target device has JSR-82 (Bluetooth API for Java) support, you might be able to support A2DP within J2ME.

However, this is a complex protocol and a lot of joy, i think:
+ A2DP > GAVDP > AVDTP > L2CAP
+ AVRCP > AVCTP > L2CAP.
If you go commercial with that, you have to apply for a Bluetooth SIG membership and go through conformance (qualification) testing, too.

Perhaps current implementation my be too slow for all of this. No ideo or experience.

MSI BluePlayer: A2DP for MIDP 2.0/CLDC 1.1/JSR-75/JSR-82 phones.

However, it is restricted to MSI A2DP headsets like their FS111 or FS510, so for all interesting in this, I would ask them for a license rather than do it again. They even went through Java Verified and Bluetooth Qualification.

PSM values of AVDTP/AVCTP might be an issue in JSR-82…
