RAK8211, code stop when not connected to Web IDE in any way

Using the console.log command causes code execution to stop when the Web IDE is not connected.
As written in the command note, it seems to occur anyway.

Note: If you're connected to a computer (not a wall adaptor) via USB
but you are not running a terminal app then when you print data
Espruino may pause execution and wait until the computer requests the
data it is trying to print.
