I run Noble on the Raspberry Pi 3 (with Bluetooth) and i receive RSSI values from the nearby beacons that i have. However, if noble is ran the whole time i occasionally get the following error. Please help solve this issue.

```auto
/home/pi/node_modules/noble/lib/hci-socket/hci.js:526
debug('\t\tdata len = ' + len);
^

How are you using this in Node-RED?
