Hi.  
I am trying to use node-red-contrib-noble-bluetooth module on Node-RED 2.1.4.  
Installation of the package and required package @abandonware/noble went flawlessly. Unfortunately, the package is not present on the palette, and the dashboard displays an error ERR\_DLOPEN\_FAILED.  
node version -\> v17.3.0  
Any ideas?

Based on [this issue](https://github.com/abandonware/abandonware.github.io/issues/13#issue-782867295) I'd guess node v17 is the problem.

Try downgrading to v14lts (I suspect v16 will also be an issue)

You were right. Downgrade nodejs to v14.18.2 helped.  
Thx.
