Totalbytes settable . #287
Description
Hello everyone,
the request comes from a problem I found in the pid request in service mode 22.
Specifically the PID 22 D525, but essentially on all pids in mode 22 (OPEL,PEUGEOT) with OBD Vgate Icar Pro ELMduino 3.4.0
In this mode, in the response to the pid there is no value consistent with the totalbyte (line="203"--totalbyte=6!!!), therefore in the next phase the "Response data" is truncated in advance (see log below) ... in reality the totalbyte = 6 comes from an overflow.
Currently I have solved the problem by forcing the totalbyte, but it would be nice to force it manually in case of need.
Hello and thanks for everything
Luca
see "Found line in response: 203" ----> Totalbyte = 1030 :) ---> overflow ---totalbytes = 6
