Summary0000602: There is no response when trying to pair BT via [NUGU] key
DescriptionIt has been observed sometimes that there is no response on BT pairing from STB even blinking LED when trying to pair BT via [NUGU] key.

[Test Procedure]
1) Make sure that A RCU is in BT connection
2) Trying to pair BT via [NUGU] key with B RCU
3) Verify if BT connection is normally established by B RCU

[Actual Result]
In step (2), STB never performs any behavior for pairing BT even if LED is blinked.

[Expected Result]
BT connection must be normally established by B RCU

[Version]
-. v15.502.8

Hi Jim,

The similar issue has been observed in v15.502.10.
Could you please check the attached log?

The test procedure is as follows.

1) Booting STB
2) STB and RCU are in BT connection state, but no key is operated
3) After unpairing via [*]+[Home], trying to pair BT via [NUGU] key
4) But there is no response after the popup, "trying to connect BT", is displayed
5) Trying [NUGU] key again, but error code 33 is encountered
6) Trying [NUGU] key again and BT connection is OK

Hi Eric,

In my test, it's total 15 times, 12 times ok.
The 3 fails are: 2 code_11 and 1 code_33.
The fail rate is similar to "just re-pair using key * and # with only one RCU"
And after the 3fails, press MIC again can recover, and I don't see any other issues.

In the issue description: "STB never performs any behavior for pairing BT even if LED is blinked."
Sorry but please help to convergence issues.

For (2), RCU after power off/on or reboot, please go 0000601
For (5), pair fail with code 33, please go 0000533

Hi Jim,

Thanks for your feedback.

Ok, let's manage these kinds of issues in ID-601 and ID-533.
I will close it after verifying it with the next official version.
