Hi,  
I installed node-red-contrib-generic-ble from the palette, but now cannot uninstall it. Advice will be appreciated.

When I open NR now I get:

I have deleted all the flows with the ble nodes and even deleted the tab with ble node on it.

In palette and I disable all and try to remove the node:

The log shows ( no idea what to look for):

Side issue: I copy and paste the log and it annoying shows everything in bold large font caps as seen above, is there a html control char somewhere?

I have also restarted NR and tried again, but same results.  
How do I remove the ble node?

Thanks,  
Ken

If you are on node-red 0.20.x you can stop node-RED (`node-red-stop`) and then start it in safe mode. (see [https://nodered.org/blog/2019/03/12/version-0-20-released](https://nodered.org/blog/2019/03/12/version-0-20-released) and read the section `Runtime`)

Once you remove the node, you might check to see if there are any used configuration nodes. Look n the right sidebar under the configuration tab.

Hi tried stop and --safe as suggested, still the same:  
pi@raspberrypi:~ $ node-red-stop

Stop Node-RED

Use node-red --safe to start Node-RED again

Also tried:

cd /home/pi/.node-red  
npm uninstall node-red-contrib-generic-ble  
I stopped NR first then:

pi@raspberrypi:~ $ cd /home/pi/.node-red  
pi@raspberrypi:~/.node-red $ npm uninstall node-red-contrib-generic-ble

Still the same, when I start NR I still get:

In the node red editor, search ble.

You probably have some nodes in a flow (probable a config node)

Find them, delete them, deploy, fixed 👍

Similar to what he said...

Did what you and zenofmud suggested, using the palette on configaration nodes, listed all the nodes but no ble nodes in config node...but there is an unknown node greyed out. I click information and it was ble. Detele it still the same, then I realise that I have to deploy to make it happen.  
Now it is all good, thanks guys for a speedy fix!  
btw Steve, can you elaborate on how to search ble using node red editor?

For future reference you should not do this unless you understand the consequences, it may update nodes that should not be updated. The message comes from npm and confuses many.

Press CTRL+F or menu button (top RH corner --\> search flows), type in ble
