  • Thanks for an update, @laura and @matt@laura  I have a relatively low signal which is not oversampled, thus I can not simply filter out the dropouts with median filtering. My approach was to catch the frequency of the BT activity and remove it, but …
  • @EricAs a brief update - I have tried the external ADC ADS1115 to measure the same singal and observed the same dropouts. I was only able to fix it by powering from external 3V source. I guess the voltage from a battery is going down periodically du…
  • @EricTrue, I do not need it to be that fast. 50Hz (20 ms) would be just fine.  I'm trying to figure out where are those outliers are coming from (as shown on the original post). Could you share your code / settings for the 10ms sampling? Thank yo…
  • @Eric, I've used the updated API with download fix and was able to get 1 ms resolution data from logging. There are dropouts there as well with periodicity of 39 measurements. It looks like they are somehow correlated with the timing from log mes…
  • Thanks, Eric.I would expect to have around 500 + slow (1Hz) component. It is in fact PulseSensor. Have you observed such thing as well? I've tried to do the logging, but somehow I was not able to read out the values. Accelerometer logging/downlo…
  • interesting discussion. I have a similar problem - every 60 seconds I would like to log accelerometer data for 15 seconds (with 12.5 Hz frequency) and then download it. I does work a couple of cycles with downloads performed to the very last entry p…
