Closed fpedd closed 3 years ago

high load on raspi causes can packets to get lost. -20 nice value does not help

maybe increase rx buffer size? not yet tested http://socket-can.996257.n3.nabble.com/increase-buffer-size-td2024.html

maybe pi 4 (with overclocking TODO) will be sufficiently fast?!

Issue closed. Problem arose due to reception handler which discarded messages if they weren't in right order. False order can occur if high bus load on CAN, since CAN works with a CSMA-CD algorithm on bus.
