| Subject: [PATCH] [Python] Convert DiscoverCommissionableNodes to asyncio | ||
| (#34033) | ||
|
|
||
| * [Python] Convert DiscoverCommissionableNodes to asyncio | ||
|
|
||
| Make the discovery of commissionable nodes Python asyncio APIs as well. | ||
| This avoids blocking the event loop when using the API. | ||
|
|
||
| The implementation is also safe to be used with the Python asyncio | ||
| wait_for() function: The discovery process will be cancelled if the | ||
| timeout is reached. | ||
|
|
||
| * [Python] Adjust tests to use new DiscoverCommissionableNodes API | ||
