Hello everyone, I'm currently trying to get a device to do isotp. Sending and receiving seems to be working perfectly fine. I'm having the issue that when sending a packet, I can see sporadic violations of the receivers requested min tx separation time. The pattern always seems to be the following: Imagine the receiver requests a min tx separation time of 2 ms in a control frame. I then sometimes get consecutive frames with the following scheme of timestamps on an externally connected logger .. 0.0 ms : CF#1 2.5 ms : CF#2 4.0 ms : CF#3 .. In this example CF#2 is delayed by .5 ms on the wire while CF#3 is sent .5 ms too early when I look at the delta between CF#2 and CF#3 . To me it seems that, while the messages are put into some tx-queue at the correct time, they are not actually put on the wire at that exact time leading to CF#3 being put on the wire too early. I'm probably completely in the wrong here, but I would greatly appreciate any input. Regards, Maik
