Using le\_mdc\_StartSession I get the following ping return

```
root@fx30s:~# ping 8.8.8.8
PING 8.8.8.8 (8.8.8.8): 56 data bytes
ping: sendto: Network is unreachable

```

I changed one implementation per system (“cm data connect”); disabling the sandbox, but the cm command was not recognized:

`Feb 23 08:35:05 fx30s user.err Legato: =ERR= | mqttPublisher[2788] | cm: not found`

But it worked out using the full path to the cm.

` system("/legato/systems/current/bin/cm data connect");`

Thank you for your help!
