MKR WiFi 1010 + MKR 485 + Nicla Sense?

Official Hardware Nicla Family Nicla Sense ME

Hello!

I have a requirement to read Nicla Sense data and data from a RS485 device on the one MKR WiFi 1010 board. I can get the Nicla Sense and 485 shields to work separately with the board, but when I try to stack them all together, the Nicla sensor values are printed to the serial monitor fine, but the 485 shield does not work (the data packet I send from my pc serial terminal to the 485 shield via USB to RS485 converter is not printed on the Arduino IDE serial monitor).

I've tried setting up the Nicla as a shield and via ESLOV, but still not luck. Is there a pin conflict somewhere that's blocking the 485 shield comms with the board?

In case anyone else has this problem in the future, I got this working....

In order to get comms working with this stack, the Nicla cannot be connected either via the ESLOV or as a shield. It only works with the following pin connections between the board stack --- Nicla:
5V --- 5V
VCC --- VDDIO_EXT
GND --- GND
SCL --- SCL
SDA --- SDA
