Morning Michael, Thank you for taking the time to reply, I did get there in the end and now have battery soc and pack voltage in the app, :-) Your suggestion helped me tidy up my work thanks. Just need to work out a few more and then get some help how to do a pull request and get a graphic of the vehicle in the app Regards Shane

can any one help me with a bit of code to retrieve ve some data from ecu can1/6f2 00 4c 00 00 01 97 bc 00 as i cant poll this ecu it just broadcasts when its active, ive tried polling it but does not respond, i need to choose one byte and allocate it to a PID.
I don't know what you mean by "allocating a byte to a PID", but if you want to process frames received directly, simply override IncomingFrameCan1() (or …2/3/4 depending on your bus).
Reduced example:
void OvmsVehicleXYZ::IncomingFrameCan1(CAN_frame_t *p_frame) { uint8_t *d = p_frame->data.u8;
switch (p_frame->MsgID) { case 0x6f2: // for example, assuming the SOC is in byte 1: StdMetrics.ms_v_bat_soc->SetValue(d[1]); break; } }
If you're outside a vehicle context, you can register your own CAN receiver by creating a queue and calling MyCan.RegisterListener(). See the vehicle module for an example.
Regards, Michael
