The code should be exactly the same... You can just use setScan/requestDevice/etc and look at the
rssivalue in what's returned.Or, if you've got an active connection between the two devices you can use
setRSSIHandler(https://www.espruino.com/Reference#l_BluetoothRemoteGATTServer_setRSSIHandler) - with the active connection it is a lot more power efficient than constantly scanning for advertisments.
