How can Me Orion board communicate with Arduino Uno which is using WiFi Shield?

#1

Hi, i’m a beginner of Makeblock. I’m working on a project which is using XY Plotter of Makeblock.
I want to control step motors via WiFi network so i’m trying to use Me Orion to control motors and Arduino Uno for WiFi connection. At here, i’ve got a problem. i’ve found ICSP pins on Me Orion board so i thought that okay my MCUs can communicate each other through SPI communication. However, if i try to use WiFi shield with SPI communication, WiFi is not working. So i tested some things and i figured out that if i connect pin into pin number 13 which refers to SCK pin for SPI communication, WiFi doesn’t work and i searched some info of that problem on the internet, i couldn’t find proper info that i wanted.
So my question is how can i use WiFi Shield and Me Orion at the same time?
ICSP connection is the only way??
please help me to solve this problem… i’m stuck with it…
