Hi,  
i use a NanoPi with ubuntu, snapd, node-red and want to manage WIFI settings via forms and exec nodes

My image comes with "nmcli" (Network manager cli) with works perfect via putty (command line)  
[http://wiki.friendlyarm.com/wiki/index.php/NanoPi\_NEO2#WiFi](http://wiki.friendlyarm.com/wiki/index.php/NanoPi_NEO2#WiFi)  
CLI commands works fine:

**Via exec-nodes it is NOT possible to use the commands.**

FYI:  
Other cli-commands work fine (example "timedatectl")

What can i try? Can anybody gives me a tip?

Thank you  
Alexander

Try giving it the full path to the nmcli command. `which nmcli` will tell you where it is.

You are running in a snap which is a virtual environment. So nmcli is not included inside the snap.

By default we use strict confinement. You can relax that by using --classic mode..

So, i switched back to an "nativ" installation of node-red without snap.  
In this case i can use NMCLI directly from Node-RED

I want to learn more about snapd, but at the moment i have not the time 😓

I switched to snap because i had problems with connecting to ttyUSB0, But for that i also have found a solution. See this post:

I have a heatpump system with an USB-Interface which sends and receives simple Strings like "13 1234" Want ro read/write this strings. With my Device A it works Device B not works (no data in or out), but i have no idea why. When i Install the older version of the node-red-node-serialport node it works fine. But what can i try, that i can use newer version? THANK YOU Device A: Hardware NanoPi NEO2 Ubuntu core 16.04 L…
