It is strange that the rssi I saw never went over -97, it is similar to what people saw here https://devzone.nordicsemi.com/f/nordic-q-a/27113/nrf52840-coded-phy-sensitivity?pifragment-684=2 with alpha versions of S140 softdevice and they later claimed that bug was fixed (two bugs actually) and I should see up to -103 dBm in the scan
also in this article https://www.cnblogs.com/dong1/p/15434159.html they say "With Coded PHY, the scanner can still detect adv packets of signal strength around -101 dBm"

Did you see lower value than -97?

I tried testing long range mode, bangle 2 as transmitter, magic 2v21 s140-6.1.0 as receiver, I got to see -101dbm for just a moment , -99/-98 dBm a few more times, but in practice it looks like normal BLE range. If the BLE long range can indeed go 1km, it would be super. Is the 1km an exageration, or maybe the long range on espruino is not really working yet?
```
lala=[];
NRF.setScan(function(d) {
 if (d.rssi<=-97) lala.push(d.rssi);
},{phy:"coded"});

>lala
=[ -98, -97, -97, -97, -99, -97, -97, -97, -98 ]
```
