  • Hi Laura/Matt, Matt previously demonstrated in Windows10 machine via 'some quick tests ' that v1.7.3 is 1.5x faster than v1.4.5. Srinivasa also replicated Matt's test and confirmed that v1.7.3 is 1.5x faster than v1.4.5 in Windows device. But,…
    in Observed the change in download recorded data from sensor to phone Comment by qpal1012 May 2022
  • Hello, Is the above firmware update (1.7.0 for PHY change for faster download) planned to be implemented to MMRL too? We really hope so. We earlier purchased MMRL of 100ea and we have been waiting for the (PHY change for faster download) update in …

  • Matt, Thanks for your reply. * 'LE 2M PHY' is the one that we want to use. We don't want to use and so we want to disable 'LE 1M PHY' as we want higher data rate. * Firmware 1.4.4 seems to use 2M PHY (higher data rate) which we want. But Fi…

  • Hi Laura, I see. Thanks for the clarification. I was wrong that I thought it was in byte. Now I know that it is the number of entries. * Is each number counted toward 524288, so one sampling (time=1, x=1, Y=1, z=1, total 4) counted as FOUR e…
    in Max logging data size Comment by qpal1012 February 2021
  • Hi Laura, So, how should we estimate correct data size for given sampling rate? MetaMotionR sends larger data (2MB) than the estimate (524kB) because MetaMotionR uses a combination of both logging and streaming at the same time even though we set…

  • @Laura said: See our tutorials calculator section Hello, Thanks for pointing the site. I calculated the max log entry for 800Hz sampling with accelerometer selected (no other sensor selected). Then, it gives 524kB for max log entry (…

  • We wrote a code to simultaneously record the acceleration data from two MMRs. As you can see from the attached data, the time difference between the two sampled acceleration data are quite different. The difference even changes during the measuremen…
    in Synchronous sampling / acquisition / record from the multiple MMR Comment by qpal1012 November 2020
  • Hi Laura, Thanks for the information. So, an iOS app in an iPhone can connect 3 MetaMotionR at the same time and acquire synchronous data from the 3 sensors at the same time. Is my understanding correct? If yes, would it be possible to share the …
