the remote (in our case the Nvidia Jetson) seems to have trouble sending messages over iso-tp in specific cases using candump, we can see that the flow-control (FC) frame is received before the last frame from the block (bs=8) is sent, which is not expected. A dump: ``` can0 3F2 [8] 27 2C 2D 2E 2F 30 31 32 <- frame #27 = 7/8 can0 1F2 [3] 30 08 00 <- FC frame can0 3F2 [8] 28 33 34 35 36 37 38 39 <- frame #28 = 8/8 ``` Probing the can bus, we can see that frame #28 is sent before the FC frame is responded to the Jetson (as per iso-tp protocol). But the Jetson doesn't seem to correctly order these frames and each time it happens, transmission stalls. Adding some delay for the FC response on the mcu side seems to fix the issue as the Jetson now has more time to set up the reception of the FC frame.
