Connectivity issues on Raspbian Stretch

[grover]

When running node test.js on a Raspberry Pi 3, I get the following output:

connectAndSetup
disconnected!

Running hcidump alongside gives the following output:

It hangs on LE Read Remote Used Features and gets stuck there until the Flower Power device disconnects.

uname -a: Linux raspbee 4.9.73-v7+ #1072 SMP Sun Dec 31 19:37:41 GMT 2017 armv7l GNU/Linux
bluetoothctl -v: 5.23

I get the same results on a Raspberry Pi Zero W with:

uname -a Linux leinwand 4.9.78+ #1084 Thu Jan 25 17:40:10 GMT 2018 armv6l GNU/Linux
bluetoothctl -v: 5.43

Any ideas?

Here's also the btmon output captured on the Raspberry Pi Zero W:

Hi, exatly the same, even tried on Debian Jessie and Ubuntu 16 without success.

It seems that the issue goes away once an external USB BLE Dongle is used. An additional finding of the log dumps above is that my code suffered from noble/noble#765

by using npm install noble@1.8.1 it's working great!
