Summary0001926: [Smart3] [UI541] Request to analyze VoC logs
DescriptionHi Kinbay

UI541 FW has been distributed in the field and the VoC is relatively high compared to other manufacturers.
https://jira.skbroadband.com/browse/BTVV-7747

So we have to analyze the VoC log to find out the cause.
Now we should focus on the following two issues
1) RCU button issue
2) No input signal

There are currently many VoC logs and we will ask you to analyze the log after the 1st review.
If we attach the log, please analyze it.

Thank you
YK.Jung

 Hi YK,

After checking log files, we can see BT RCU are disconnected due to different reasons.
You can check all GATT fail reason in 'system/bt/stack/include/gatt_api.h'.
I list here for reference.
 0x08 => connection timeout
 0x13 => connection terminate by peer user
 0x22 => connection fail for LMP response tout
 
For 'reason=0x0008', we also have same discussion on Mantis. (https://btracker-cns.fii-foxconn.com/vaas/view.php?id=1674)
For 0x13, 0x22, we also don't know the root cause from log messages if we don't have air sniffer packets.

However, I see a differnt error. (8C_C8_4B_0A_EB_83_20240420113139)
It may be caused by App doesn't really release GATT connections.
You can find "can't Register GATT client, MAX client reached: 32" in the log.
This should be checked by App vendors.
I list my review results as below

8C_C8_4B_0A_EB_83_20240420113139 -> uptime 141 days, GATT connection reached 32, reason=0x0008
28_CD_C4_FA_61_6A_20240420171129 -> uptime 2 mins, reason=0x0008
28_CD_C4_FC_F4_6D_20240420145109 -> uptime 2 mins, reason=0x0008
28_CD_C4_FD_6E_9F_20240420113820 -> uptime 16 days, reason=0x0022
38_D5_7A_D8_63_6A_20240420153122 -> uptime 5 mins, reason=0x0013
B4_B5_B6_FF_63_6D_20240420225322 -> uptime 2 days, reason=0x0013
BC_F4_D4_F9_F2_8B_20240420145329 -> uptime 3 mins, reason=0x0008, 0x0013
D4_1B_81_FE_E3_FB_20240420210321 -> uptime 18 mins, reason=0x0008, 0x0013
