From 86ab9dcb5e074a532956b0034a975b8a0fadd3ab Mon Sep 17 00:00:00 2001 From: Arkadiusz Balys Date: Fri, 13 Oct 2023 09:32:56 +0200 Subject: [PATCH] [nrfconnect] Add a delay to last fabric remove action In some cases, a last fabric removal action should be delayed to avoid race conditions and allow the device to finish all currently running tasks. To control the delay use the CHIP_LAST_FABRIC_REMOVED_ACTION_DELAY kconfig. By default it has been set to 500 ms. --- .../nrfconnect/chip-module/Kconfig.features | 9 +++++ .../nrfconnect/main/include/AppTask.h | 3 -- .../nrfconnect/main/include/AppTask.h | 3 -- .../nrfconnect/main/include/AppTask.h | 3 -- .../nrfconnect/main/include/AppTask.h | 3 -- .../nrfconnect/main/include/AppTask.h | 3 -- .../util/include/FabricTableDelegate.h | 33 ++++++++++++------- .../nrfconnect/main/include/AppTask.h | 3 -- .../nrfconnect/main/include/AppTask.h | 3 -- .../nrfconnect/main/include/AppTask.h | 3 -- 10 files changed, 31 insertions(+), 35 deletions(-) diff --git a/config/nrfconnect/chip-module/Kconfig.features b/config/nrfconnect/chip-module/Kconfig.features index 522b52f8b7fe3d..9b5a1e7aee9029 100644 --- a/config/nrfconnect/chip-module/Kconfig.features +++ b/config/nrfconnect/chip-module/Kconfig.features @@ -267,4 +267,13 @@ choice CHIP_LAST_FABRIC_REMOVED_ACTION endchoice +config CHIP_LAST_FABRIC_REMOVED_ACTION_DELAY + int "After removing the last fabric wait defined time [in milliseconds] to perform an action" + depends on !CHIP_LAST_FABRIC_REMOVED_NONE + default 500 + help + After removing the last fabric the device will wait for the defined time and then perform + an action chosen by the CHIP_LAST_FABRIC_REMOVED_ACTION option.
