| Summary | 0001047: [BFX_AT100][BTVV-1951] VOC is increasing for Voice Search on Smart3. | ||||
| Description | hi kerwin as send a mail, skb VOC is increasing about voice search fail. so I create a ticket 1 week before : 3 2 week before : 11 3 week before : 15 4 week before : 6 this week :15 Total 50. we need to explain or to solve this issue. please see a log. as specification, BT is disconnect within 18 hours. However, many SKB user have some problem about Voice search fail or don’t work RCU. So we need to make a plan for solving or explanation about this issue. 1. Which case does BT is disconnected except Idle Timeout ? 2. As explanation on mantis, BT is connecting within 10s. If it is right, why does SKB user meet many Issue about BT problem? You need to do brain storms about SKB VOC. Which case does we can’t connect to BT again? Please give your opinion as variety . since we need to explain it to SKB user about many case. 3. As you know , BT10 has some problem to connection. Please explain to us again with a technical note. Case TVstorm , BFX-AT100 is difficult to pairing with BA01 RCU , since it is searching with using BT address(oui) area in Dae-woo building. Since Intek Smart3 is used with HCI Module (MD-BRC101). So this module is used in a similar area. (401920-100001 ~ 401920-100044 , 401920-111480 ~ 401920-111520) According to, TVstorm applied Major Device Class in V15.520.8. we can distinguish BT device but although set filter as 0x400, we seem meet A2DP searching fail as talked upper, please explain it with a technical not for SKB manager. please agenda #1 , #2 . we need to feedback more fast. | ||||

hi kerwin according to SKB explanation, it is increasing VOC Item at 12/7. so we especially investigate a log from 12/7. after reboot box and repairing with RCU, It works well in many case. so Could you check whether if is this related to android BT Upgrade service ? |
|
|
Hi Jason, I am still checking for the logs and will update later. But I don't understand about you question about "BT Upgrade service". Foxconn don't have any process to update android BT service on Android P. Thanks ! |
|
|
Hi Jason, I found there is a tombstone in the log files which is similar with another issue on BTF. (https://mantis.cnsbg.foxconn.com/vaas/view.php?id=947) We already have a workaround solution on BTF to avoid audio server crash. It can be also applied to Android P. However, we don't have any update plan on Android P of ATV model, right ? I think the root cause is remaining capacity of battery is low. Smart3 is launched for more than 1 year, for some users it is the time to change battery. This is why VoC issue is increasing recently. Please check it with SKB and end users. Thanks ! |

hi kerwin although you find tomstone, I can't find it in a log. this issue is don't work for voice search and don't pairing with RCU again. you think also second issue(don't pairing) is related to your comment ( tombstone issue) ? as inform to you, we have a chance to upgrade in UHD4 . So please update it in advance. case ATV, We will have a chance to upgrade as android 10 soon. |
|
|
Hi Jason, Please search for keyword "android.hardware.audio@2.0-service" in tombstone files. And for sure, we will apply it to AOSP model since it is for NUGU voice. Thanks ! |
|
|
hi kerwin. sorry to bother you , my talking is for main.log. it don't find it in main.log. it isn't a big issue. please ignore my talking. mantis 947. We already fix it and commit to BitBucket, the fix will be included in next release. Can you give a commit item? since I have to leave some comment on SKB voc with an explanation. if happen audio crashed issue, RCU don't pairing again if RCU battery's capacity is full? |
|
|
Hi Jason, The workaround solution on BTF is to avoid audio server crash. Actually, root cause is "RCU battery" which results in RCU disconnected with STB. If RCU battery always has enough capacity, RCU will be always connected and we don't need the workaround solution. Thanks ! |

hi kerwin as you know it, we also make new fw for UHD4_522. So please apply this patch for UHD4_522. |

hi kerwin. SKB RCU Manager ask it to FXN below question. . skb manager think there is no problem about battery capacity. since they also check a log as keyword" battery". . please explain it regarding to a relationship between audio server crash and Voice research. why does audio crash affected for audio voice search ? . please explain it regarding to a relationship between rcu disconnection and audio server crash. ( when push voice search button in rcu disconnected, IR Code is transmitted for showing a guide for RCU repairing ) as you feel upper comment, skb manager think it is a critical item in VOC. So when you give an answer to us, please give a right answer with a technical explanation. . |

Hi Jason, . skb manager think there is no problem about battery capacity. since they also check a log as keyword" battery". ==> I don't know how SKB check about battery because I don't find it in log files. From the log file, audio server crash at the same point with Mantis947. . please explain it regarding to a relationship between audio server crash and Voice research. why does audio crash affected for audio voice search ? ==> Audio HAL reads data from RCU after pressing NUGU button. If RCU is disconnected suddenly, driver will be removed automatically. Audio HAL keep use the same pointer to read data. As a result, there is a NULL pointer access in audio HAL. . please explain it regarding to a relationship between rcu disconnection and audio server crash. ( when push voice search button in rcu disconnected, IR Code is transmitted for showing a guide for RCU repairing ) ==> RCU is disconnected suddenly, not unpair. Pairing dialog will never be shown. |

hi kerwin I don't want to play a ping-pong game with skb manager about this issue. please check a log again regarding to BT disconnect reason. please see skb manager feedback. . I don't know how SKB check about battery because I don't find it in log files --> whenever push homeUI button of RCU, it is transmitted to system property as normal/low/empty. you can find as keyword ( STBGlobal: getBattery - property : 2, eBATTERY : NORMAL_BATTERY ) in a log. or you also see in BAS Profile. Finsky : [2] aafz.handleMessage(4): SCH: DeviceState: DeviceState{currentTime=1607266852599, isCharging=true, isIdle=false, netAny=true, netNotRoaming=true, netUnmetered=true, batteryPercent=42.0} ==> RCU is disconnected suddenly, not unpair. Pairing dialog will never be shown. when push voice search button in rcu disconnected, as transmitted as battery empty key value, it is shown pop-up window for changing a battery. if don't see it,, it guess it is related to mantis 914. https://mantis.cnsbg.foxconn.com/vaas/view.php?id=914 SKB manager think if this issue is related to BT Disconnection, disconnection's reason isn't a low battery. |

Hi Jason, I don't think the 2 log files(main.log, main.log.1) are enough to present user's issue. Because the duration of main.log/main.log.1 are too short. It contains messages within minutes. This is why you can't find tombstone in main.log/main.log.1. From our previous project in Taiwan, we also had experience that RCU needs more power before it start to send voice data. At that time, BT RCU is disconnected suddenly. |

|
hi kerwin I understand a comment. but SKB service man tried to capture a log when issue happen. so according to skb manager talking, a capacity of battery isn't low in capturinged log. so as your comment, if may don't find about tombstone in main.log/log1, why does BT is disconnected ? but skb user can pairing it again. this issue is resolved. and I think also this issue isn't related to Low battery. so BT disconnected issue isn't a real reason about this issue. |
