I doubt that this is on topic, or that I can make it so, in order to get an answer on our main site (can I?). please note that I am not looking for an answer here in Meta.
Basically, I want to implement a tracking system, to track my movements around my house.
I will wear a BLE wristband and will position SBCs (maybe Orange Pi, I haven’t decided) at each doorway between two rooms to detect the wristband.
BLE is not a protocol that I know – what comes next? How does one of my door sensors know that my BLE wristband is passing it? Does it attempt to pair, or what?
I will handle all the higher level stuff, like the band being detected by two doorways at once – although I would welcome advice; do I detect which room I am in by signal strength, or by knowing which room I came out of?
I don’t even know where to start, so any advice would be greatly welcomed.
