    Lumia / other WP phones maximum accelerometer sample rate

    I'd need to do some quick sampling with WP and was wondering whether any Lumia / other WP device is capable to record accelerometer readings in, lets say, 200Hz (5ms interval)? Atleast the emulator only lets me to sample with 20ms intervals.

    Code:
    accelerometer.TimeBetweenUpdates = TimeSpan.FromMilliseconds(1)
    actualSampleRate.Text = accelerometer.TimeBetweenUpdates.TotalMilliseconds & " ms"
    So, if this is the case with real devices too, is there any trick to override it?

    Thanks in advance!

    You could check: http://msdn.microsoft.com/en-us/libr...=vs.92%29.aspx , and the property TimeBetweenUpdates, documentation does state: "Different devices are capable of different rates of providing sensor data. You can query this property after setting it to see what value is actually being used. The default value is 2 milliseconds." for it, so you should actually try that before assuming what the device is capable of.

    Thanks. Yeah I noticed that earlier, but can anyone confirm to what rates e.g. Lumia 800 is capable?

    What are the odds... Nokia's developer forum and nobody has a Lumia...
