BLE proximity detection in near distance (up to 0.5m), high speed and pass-by scenario - is it possible?

Hi!

I'm exploring the option to use wearable BLE beacons and receivers in order to people interaction (e.g whenever a person is near a person). This means I have a short duration to register an interaction (30-150 ms).   What is the minimum time needed in order to register an interaction?

    Hello,

    I Googled your question and see it has been asked in other board(s), so I will not duplicate those answers.

    Max (fastest) ADV time is 20ms, so this will be a function of a number of variables, including scanning duty cycle, and how fast the connection can be established. I suggest reviewing the CC2640R2F SimpleLink Academy labs for ADV/Scanning and BLE Connections. This will give you an idea of what parameters are at play and how you can run some experiments to model your system with available dev kits.

    Best wishes
