Thanks so much for the input! We prioritize new features based on this sort of feedback.
Wireless logs: Wireless log files are definitely a feature we’d like to add, but the biggest limiting factor is that Bluetooth Low Energy has a really low transfer rate. To transfer a 1MB log would take 10-20 minutes with present iOS and Android distributions. This might still be useful for some users who embed their meters in hard to reach places, but generally it will end up being faster for people to just pop out the SD card.
Auto-connect: Yes, most users have only one meter, so this makes sense. Consider it on the to-do list.
