Hmm I may have miscounted (or taken 2 of them out) - either way, there are 5 in the code now that I've tried to include the UUID for.
ESTIMOTE
GLIMWORM
KONTAKT
PARTICLE
ROXIMITY1
I should caveat this with, that I've only tested directly with Estimote. I've had other users try others, but I haven't recorded that. I'll try and keep a record in future for anyone who uses other manufacturers, so if you decide to get any, it'd be great to start a new thread with your experiences (which I'll document on the website). And any UUID used for your manufacturer, let me know, and I'll add to the codebase.
