Assuming the ESP32 is advertising, you should be able to use something like:
NRF.setScan(function(d) { if (d.addr=="...") LED.write(d.rssi>-70); });
You'll need to change the address and probably the RSSI value as well, but that should be a good start :)

Just a quick note that doing this does use a lot of power (as the radio is always receiving) so will run the battery down quite quickly - so you might want a way of only enabling it when you need it.
Hi friends,
I am working on some project in which we have to measure the distance between two nearby device using puck.js . if distance is less then a meter . we need to emit LED.
One device is puck.js and other one is ESP32.
Help me to figure out this.
