<![CDATA[PySense not working with LoPy4]]>I have a LoPy4 and Expansion board 3.0 which is working well. I recently bought a Pysense board from Farnell, plugged the LoPy4 in, connected the USB cable and tried to connect but it failed to connect.
I am using Atom with the PyMaker plugin on a Mac running OS X. The serial port is detected but the LoPy4 wont connect.
The LoPy4 is plugged in the correct way round as per the documentation before anyone asks.

Do I have a faulty board?

Thanks

Andrew

Found option in the settings to get the port automatically.
