I’m having a problem where when I attempt to download my logfiles over bluetooth I get corrupt data, followed by what I think is a crash/reset. The symptom is it creates several new small (almost empty) logs after my failed download attempt.

I’ve attempted to “re-download” the bad log but it seems to “instantly” be done (and still corrupt) even if I delete the app data and cache and restart the app.

If I disassemble the meter and put the SD card in a computer the “corrupt” logs are in fact undamaged and readable.

Android 8.0, Firmware 1477971088, SanDisk 16GB SD card
