Help a newbie? I'm seeking to build a niche product for sale, a Raspberry Pi-based device which during the initial setup acts a BLE peripheral. (Python using dbus to Bluez.) It has a single service and 19 characteristics. I get that the first "U" in UUID stands for unique. Must that be unique among each physical product, or may it be unique among the product line? So if I sell 1,000 units (which would be a success), would I need to obtain 1,000 service UUIDs and 19,000 characteristic UUIDs? Or just 20 total, for the entire product line? The goal is so that the iOS/Android app can have that pre-set in the code and quickly discover the device, pair it automagically. I suppose the risk is of a conflict of two similar devices which are in the same vicinity of the phone, and both set into peripheral mode at the same time. But that would be a minimal risk which I could accommodate for. Christopher de Vidal Would you consider yourself a good person? Have you ever taken the 'Good Person' test? It's a fascinating five minute quiz. Google it.
