| Summary | 0001810: There is a tombstone in /vendor/bin/ledd. | ||||
| Description | I'm checking the VoC issues and there is a tombstone in /vendor/bin/ledd. I only have the tombstone file, so I think it may be not easy to analyze. But, could you please check the /vendor/bin/ledd source code again? Thank you. The firmware version : 19.536.28 | ||||

Hello, Jason, Could you please check this ticket with low priority? Thank you. Sangmin Choi. |

Hi Sangmin, Do you have corresponding logcat/dmesg? Thanks Jason |

Hi Sangmin, I fix this issue: add a case to deal with "NULL" command sent in. And I have verified it in my side. What is the commit tag number should I use? Thanks~ Sam |

Hello, Sam, Could you please explain more about your modification? Thank you. Sangmin Choi. |

Hi Sangmin, The root cause is that M/W sends a empty command to us("\n" or "NULL") (I don't know why they send this). And our LED service will crash in this case while parsing the command. So I add a error handler to bypass empty commands(if the command is "\n" or "NULL", return it). Thanks~ Sam |
