Hi! Restarting this thread, rather than creating a new one.
I just received the xBT, and I'm still a bit confused as to best placement. Could you please annotate the attached drawing? It's from a slightly different perspective than your previous upload. I'm primarily looking for more Proximal/Distal spacing.
Secondly, I'd like to do a temperature graph over time. Do you know of an NFC system that could be used to monitor the sensor at discrete intervals? Preferably without wires, but doesn't need to store a lot of data. A use case for this is doing a short workout, and seeing how body temperature changes during different activities. I fully acknowledge I may be asking the impossible.
