We’ve successfully initiated serial level communication over bluetooth to a Sokia SET550Rx, and we’re quite confident that we’ll be able to engineer this into the app.
With that said, compatibility is model specific. So if you want an external sensor device working with the app, loan it to us for a week or so, and we’ll see what we can do. Have we mentioned that we’re looking for partners for our 2014 grant application? We are.
