Hello,
This is my problem :
During the setup, i read info from a SD card. After That, i don't need the SD card anymore. I also begin listening on the network using the UDP class.
When doing that, i'm missing a lot of network packets. The system is built to receive 60 packets per second (or more) and i miss about 30 packets per second (there is an id in each packet to know if a packet has been missed)... If i comment the "SD.begin(4)", i don't lose any network packet anymore...but i can't read the info from the SD card...
Can you explain me why and how to fix that?
Board used : Arduino Ethernet R3
Thanks a lot!
