K-Line (ISO14230) sniffer

[tjwasiak]

I would like to kindly ask if it possible to setup K-Line sniffer just like it is possible to setup raw CAN sniffer? I tried with and without filters but even if I am receiving a message it is empty. Tried setting different speeds without difference.
The code I am using to setup the device:
Channel = APIFactory.GetAPI(DllFileName).GetDevice().GetChannel(Protocol.ISO14230, Baud.ISO14230_10400, ConnectFlag.NONE); Channel.StartMsgFilter(new MessageFilter(UserFilterType.PASSALL, 0)); Channel.DefaultTxTimeout = 500; Channel.DefaultRxTimeout = 5000;
I can sniff same traffic (same connection) using FTDI based blue KKL interface and STN2120 based "ELM327" device without issues.
For now tested only Scanmatik 3 as J2534 device, will try other devices (Openport 2.0 and GM MDI) when time permits...

I'm not very familiar with KWP2000/iso14230. I do know for j1850pwm drew tech implements a sniff mode connection flag to allow network traffic monitoring.
