Sorry I forgot to say that the PeripheralManagerIsReady callback time might ranging in 0.01ms ~ 250ms. Is it unstable normal? iOS limits the packet number to 4 per connection event for instance, so if the connection interval is 30ms, then I can just send 4 packet during 30ms, is that right? I'm trying to find out the low throughput issue

No, it's not negatively impacting my app. I'm just curious about the performance difference. Since Neural Engine can process the task faster with 120 FPS video, I'm wondering why we can't achieve the same processing speed when running at 60 FPS. Also, 10.91ms is only for the prediction part - other processing steps still take additional time, which might affect the video's ability to maintain 60 FPS playback
