Didier,<br>
<br>
the PID scanner normally works perfectly with multi frame responses,
but I haven't had a response that long yet.<br>
<br>
For 1503 bytes, 215 consecutive frames need to be transmitted. The
PID scanner requests these to be sent with 25 ms separation time, so
they should need 5.375 seconds.<br>
<br>
Maybe some frame gets lost, or maybe the device doesn't allow a
separation time that high for a transmission that huge.<br>
<br>
Your log quote wasn't from the re-pid component but from obd2ecu,
which has nothing to do with the RE tools. You should raise the log
level for re-pid to see more info. Another tracing option is to use
the CAN log monitor.<br>
<br>
Btw, you should never need 30 seconds timeout for a PID poll, as the
scanner checks against the last frame reception.<br>
<br>

<font face="Helvetica Neue, Helvetica, Arial, sans-serif">From the Canbus doc, I understand that the first "1x (15)" tells me that this is the first frame of a multi frame, and the length is "5df" .
The Pid scanner seems to return only "df", not "5df" data, and I can see in the log that I have around 1500 byte returned, not 220.
Any explanation ? anyone see this problem as well ?
The scan command is (I had to hack the code to allow timeout > 10sec)
