PySense not working with LoPy4

[thinginnovations]

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

Looks like I got it working, seems atom and pymkr plugin were not looking for the plugged in port, rather the one that was used first.
Found option in the settings to get the port automatically.

@thinginnovations the USB/serial conversion is provided by a PIC which runs its own firmware.

@philwilkinson firmware? It's just a usb/serial with a bunch of sensors isnt it?

[philwilkinson]

Have you updated the firmware on the pysense board?

@thinginnovations you may want to try a different USB cable and/or port to see if that makes a difference.
