Hello Markus, thanks for the feedback on the ISO-TP implementation. Indeed we're also using it every day and i did not see any issues for a long time now. The missing thing is that you currently need to set the tx_queue_len of the according network device to high values (like 1000) as the ISO-TP implementation does not react on full tx queues 8-) Regards, Oliver
