Hi all,
I use NR 0.20 on a Raspberry pi. I would like to use the Noble Node to be able to read the Ruuvitag via BLE. According to the makers, there is an issue with the NodeJS 10 version. Is there a possibility to downgrade the current version to e.g. version 8? Have looked at NVM, the default NodeJS is now 8, but when starting Nodered, 10.15.3 remains reported. Can anyone help me.
Rob

Assuming you used the pi install/upgrade script to install it, and assuming it is not a Pi Zero then first uninstall nodejs
`sudo apt-get remove nodejs`
Then edit the file `/etc/apt/sources.list.d/nodesource.list`. You should find it contains something like
```auto
deb https://deb.nodesource.com/node_10.x jessie main
deb-src https://deb.nodesource.com/node_10.x jessie main
```
Change the 10 to 8 on each line. Then run
```bash
sudo apt-get update
sudo apt-get install nodejs
```

Not sure whether you then have to rebuild everything for the new nodejs. Someone else can perhaps comment on that.

Right, after downgrading you should follow the advice in the Upgrading node.js section of
[https://nodered.org/docs/getting-started/upgrading](https://nodered.org/docs/getting-started/upgrading)

Node.js version seems downgraded. 🙂
nodered editor gives an error:
Flows stopped due to missing node types.
- sqlitedb
node-red-log gives an warning
13 Mar 22:19:17 - [warn] [node-red-node-sqlite/sqlite]
Error: Cannot find module '/home/pi/.node-red/node\_modules/sqlite3/lib/binding/node-v57-linux-arm/node\_sq lite3.node' (line:4)
I have tried to reinstall sqlite-node. But that didn't solve the problem.
Any clue?

yeah this is due to the downgrade...
uninstall sqlite-node - and also uninstall the node-red-node-sqlite node - then in the `~/.node-red` directory run an `npm clean --force` then reinstall the node-red node (only) - as per it's readme
```
npm i --unsafe-perm node-red-node-sqlite
```
and then prepare to wait - it seems to take about 40 minutes or so to rebuild

Tnx. That did the job.
