If I do a Can0.begin(1000000, filter) with filter.id = 0x70 to set a mask of 0x70, this still allows addresses of 0x110 through. If I'm understanding the documentation correctly, it will do an AND operation with the received message and then pass to a mailbox for further filtering. In this...

Some additional info...I added the following to the end of setup() to make sure the mailboxes were successfully getting a filter set. CAN_filter_t setfilter; for(uint8_t num=0; num<16; num++) { if(Can0.getFilter(setfilter,num)) { Serial.print("MB "); Serial.print(num)...
