Hi! Some vendor A2DP bluetooth codecs like FastStream or aptX Low Latency supports backchannel. Which means that they are bi-directional and in A2DP they supports not only (music) playback, but also receiving backchannel (microphone) voice. How to establish this bi-directional A2DP transfer with backchannel via bluez daemon? -- Pali Rohár pali.rohar@xxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-bluetooth" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
