Problems with acc/gyro sample rate in iOS
I'm having trouble achieving the gyro/acc sample rate that I want. Device is a CPRO. Let's say I specify the sampleFrequency property to 100 Hz, I measure 92-93 Hz streaming (both with gyro or acc). If I stream both gyro and acc simultaneously, I get around 87 Hz.
If I specify 50 Hz, the measured sample rate is about 48 Hz (47 Hz with both gyro/acc streaming). I simply measure it by counting the samples and dividing by the elapsed time.
Any ideas what this might be?
