@wuwentao IMHO we should avoid all those sleep around the code and find a proper way to handle the loop

1. I will try to merge this PR at first, as I want to publish a new release, we can try to improve it in next release (if you have any good idea and solution for it)

2. there is more PRs change need to verify with user device and debug log, they don't know how to manual test and update source code, in addition, these PRs code should NOT the finally version, still need some changes with user device test, especially the same type with different submodule, so I will disable codecov checks in github actions, and merge these PRs. as most of these PR required unit test to pass, but we should verify the code logic with user device at first, and NOT unttest, we can accept bug and error in code, and try to fix it in next release.

thanks!
