You commented on the hassle of getting the SD card out from the meter to have access to the csv file for processing. Maybe Seppy, (Dave 2) can comment, but cant you have access to the csv file from the BLE app? I'm assuming the app on android can use dropbox, etc, or maybe the app is also available for your PC?
I would like to know if this is possible with the app?
It is not possible with the app, the meter firmware does not support this.
This was discussed at the time but UEi said it would not be particularly easy, and with all the other stuff on the list it was decided not to add it Because:
a) The bluetooth app does data logging anyway
b) It fairly trivial to remove the SD card if you are doing long term standlone logging. e.g. <20 seconds to remove the card vs all day logging or whatever, it didn't seem like a big deal.
c) If you are doing a lot of serious data logging then you should have a dedicated and more versatile data logger to begin with.
