Hello Have you experience A2DP connection lost or corruption, when a user changes A2DP configuration between mono and stereo, or between 44.1khz 48khz Though I check bluez receives Close Cfm from headset , and Bluez sends set_configuration to stereo headset. However Bluez get an error” "Stream End Point in Use( 19). -.-; I couldn’t understand why this error occurs. I guess you know this situation very well.. ^^ If possible, could you explain that scenario or give me other information?
