Hello,

I want to create a system which will alert me when a dog gets close (within 5-10m) of any sheep. I have BLE 5.0 tags on the sheep (range 100m).

Assuming I have a custom device with a Bluetooth transceiver on the dog, how can I approximate distance from the dog to any given sheep? Ideally it would not require pairing since the number of sheep might exceed the cap on paired devices (I think the limit was 7 last I looked).

I was thinking signal strength could be an approximation. Not looking for any precision just need to know when dog gets too close.

Kind regards
