[Ovmsdev] can polling

[Tamás Kovács]

i found the problem:
static const OvmsVehicle::poll_pid_t vehicle_mitsubishi_polls[] =
  {
    { 0x761, 0x762, VEHICLE_POLL_TYPE_OBDIIGROUP,  *0x02*,  {       0,  10,
  10 } },  // cac
     { 0, 0, 0, 0, { 0, 0, 0 } }
  };

This (uderlined and bold thext) is in my old code is 0x01 after i chage it
to it, working.

The only thing i get the values from IncomingFrameCan1 (with old code
removed CAN_frame_t frame;.... code  )

i can use this momde or use IncomingPollReply to get data? Which is best?
