FYI, when I connected the BT Speaker(JBL flip 4) from Smart TV, it works well. |

Additional Note : From the call with Wooshin, 1. The Samsung and LG TV that can connect TV can be used for reproducing 2. FW: BMT 18(End User), Daily Build 10/21(ALT internal test) 3. STB Audio at the moment: Youtube can be used for the test 4. HDMI is connected between TV and STB |

Hi Mr Choi, we got a LG TV which can reproduce the "Samsung TV" phenomenon. the COD of the smartTV is 0x043C (AUDIO_VIDEO_VIDEO_DISPLAY_AND_LOUDSPEAKER) it should be an "SINK" device what I can do now is something like, in the function to check peer-mode if (btclass=0x043C && btname=LG webOS TV) return peer-is-source apk v124_test3 treat 0x043C as source-device test was ok but definitely a bad solution (I'm not sure what's the COD of your 2 smart TVs, if you test with the apk, please get the log for me) A2dpDeviceService rely on peer-device-mode very much I've no idea currently and will keep find out a better way (but can't guarantee) please also share to me if you have some idea |

Hi Mr. Choi, From the log it looks like swan still think the TV is a sink-device. apk v124_test4 change the way to detect the peer-mode from android framework BluetoothClass snippset. it checks the RENDER service to be sink-device and the CAPTURE service to be src-device please check if you can connect TV with this apk. moreover, test with our LG TV (OLED55B7T), once it is connected, we receive ACTION_PLAYING_STATE_CHANGED to STATE_PLAYING there's no STATE_PLAYING/STATE_NOT_PLAYING when you pause/play (test with youtube-on-TV) in this state, there's no audio output from youtube-on-swan the STATE_NOT_PLAYING is received after 1. disconnect manually with TV-UI 2. poweroff the TV 3. hit the swan BTN after this, youtube-on-swan can output audio |

Hi, Jim, I tested with test4.apk and I could connect the LG TV with SWAN. But, I couldn't connect the Samsung TV. Could you please check it? And, there is too many noise when I play Youtube on LG TV, did you hear any noise when you test it? |

Hi Mr. Choi, for Samsung TV no solution yet but some information update: 1. after few tries the TV never connect to SWAN, unplug and plug the power cable then it is ok. 2. the 2.4g bt/wifi coexistence seems not good, the audio quality is bad until I change to eth (and reboot) 3. update the FW from 1371 to 1385 but net tried yet. 4. Samsung-TV has the same behavior as LG-TV: always in playing after connected. |

Hi, Jim, Thank you for information. And, followings are test result on our side. - QN55Q80RAFXKR / Samsung / FW 1385 - Reset the network setting and connect the wired network But, I couldn't connect the Samsung TV and SWAN. I tested several times after power off/on. |

Hi, Jim, I tested with Yamaha YAS-109 which is a sound bar. The audio is playing without lag or jitter and also there is no sync issue. Samsung and LG TV have no issue with YAS-109. I think we should improve our device. |

|
Hello, Jim, Do you have the Synaptics reference B/D? If yes, could you please test with ref B/D? |
|

Hi Mr. I'm still working on it. A bug was found and fixed to improve the pairing. Please check if 125_test1.apk could pair the TV better. Now we're checking the noise issue. |
|
|
Hi, Jim, I tested with A2dpDeviceService_125_test1.apk but I still can't connect with Samsung TV. Could you please check the attached logcat? Thank you. |
|
|
Hi Mr Sangmin, from the log it is still ERR_AUTH_FAILURE, which should be fixed in 125_test1.apk please help to get more informations 1. set all debug level to 5 in /system/etc/bluetooth/bt_stack.conf 2. setprop persist.bluetooth.btsnooplogmode full 3. reboot and pair 4. after fair fail, share me the logcat and /data/misc/bluedroid/btsnoop_hci.cfa |

Hi Mr. Sangmin, from hcilog, we still can't locate the root cause the fail is "Simple Pairing Complete" timeout, before the fail, both side should accept the DHKey. this need air log to know which side didn't accept. do you have the equipment to catch the air log? besieds, I need one more information, could you please check the pair to Samsung-TV after unpair the RCU? |
|
|
Hi, Jim, I tested with other SWAN device and it works(pairing and play audio) well without A2dpDeviceService_125_test1.apk. I think the device I tested before has some problem on bluetooth. I'm sorry I didn't expect about it. This issue can be closed now. Thank you for your help. |
