  • bleak version: 0.7.0
  • Python version: 3.7.0
  • Operating System: MacOS

Description

did_update_value_for_characteristic will potentially be called after the characteristic value has changed again due to asyncio scheduling, causing the callback not be able to receive the old data.

What I Did

This can be fixed by the pull request #241.

This is an error I also encountered when using a MetaWear device with bleak. It needs to be fixed. Thank you for finding this!
