Considerable lagging of GATT characteristic notifications after upgrading to PySide6.7.0

XMLWordPrintable

    • Windows

      I tried to upgrade my Windows BLE client from PySide6.2.2 to PySide6.7.0 and I noticed a considerable lagging in the BLE connection with the same piece of H/W. The lagging was relativly very large (~ 1 second). I do not see such lagging with PySide6.2.2
      It is also worth mentioning that:

      • My H/W sends gatt notifications at frequency = 100Hz (i.e. 100 samples per second).
      • Issue occurs on both windows 10 and 11
      • I also tried pyside6.7.0 on macOs and it worked pretty fine (i.e. didn't experience any lagging).
