Hi Duncan,
Unfortunately no, you must remove the SD card to get the data. It’s possible on a hardware level to stream out over bluetooth, but I haven’t implemented this feature yet. It wasn’t a priority in the beginning because there was supposed to be a slot in the side of the case to easily extract the SD card. We had to close this slot during safety testing to get our CATIII 600V rating. Sorry for the inconvenience. You can read more about those tests here:
Some users have ground the slot in the side of the case open again with a dremel, but this obviously voids the safety rating.
Let me know if you have other questions. Best
