Was: "Only rx -no tx while loggin Carscanner OBD2 Request To MQTT" is: Genesis GV70e SoC #105

Open Gics78 opened 6 months ago

Gics78 commented 6 months ago

Hi,

I am trying to setup my Genesis GV70e in Homeassistant. I'm using this guide. The Genesis should be close or identical to the Hyundai Ionic 5.

When continuously reading SoC in CarScanner App MQTT-Explorer only shows me rx-topics - there is no tx logged so I can't figure out the correct PID. grafik

The MQTT messages look like this: {"bus":"0","type":"rx","ts":12489,"frame":[{"id":2028,"dlc":8,"rtr":false,"extd":false,"data":[16,62,98,1,1,239,251,231]}]} {"bus":"0","type":"rx","ts":12424,"frame":[{"id":2028,"dlc":8,"rtr":false,"extd":false,"data":[40,18,0,0,0,0,7,38]}]} {"bus":"0","type":"rx","ts":12414,"frame":[{"id":2028,"dlc":8,"rtr":false,"extd":false,"data":[39,216,0,78,110,102,0,3]}]} {"bus":"0","type":"rx","ts":12404,"frame":[{"id":2028,"dlc":8,"rtr":false,"extd":false,"data":[38,0,0,98,146,0,0,92]}]} {"bus":"0","type":"rx","ts":12404,"frame":[{"id":2028,"dlc":8,"rtr":false,"extd":false,"data":[38,0,0,98,146,0,0,92]}]}

The only thing constant is the CAN ID 2028. So I'm kind of stuck. Is CarScanner IOS at fault? Might there be a wrong setting? Why are only rx messages captured?

I'm confused and looking for help!

Thank you

Okay, found my mistake: forgot to enable MQTT to elm327 log BEFORE Carscanner... now I got a tx frame: {"bus":"0","type":"tx","ts":11333,"frame":[{"id":2020,"dlc":8,"rtr":false,"extd":false,"data":[48,0,0,170,170,170,170,170]}]} and response: {"bus":"0","type":"rx","ts":11331,"frame":[{"id":2028,"dlc":8,"rtr":false,"extd":false,"data":[16,62,98,1,1,239,251,231]}]}

So Can ID 2028, PID 98 What do I chose for index, start, length and expression? Seem like it is different from Hyundai after all...

meatpiHQ commented 5 months ago

@Gics78 can you please post the rest of the frames? The tx frame show that it's a multi frame response, so its similar to what this user got in his log.

@Gics78 is this for the SoC request?

Gics78 commented 5 months ago

This is for "[BMS] State of Charge BMS", I am wondering if I should have rather choosen "[BMS] State of Charge Display". Both should be 87-90%. PID of Display seems to be 3. Should I re-log?

@Gics78 I suspect it might be this frame B1/2. Can you please post more frames logs at different SoC levels?

@meatpiHQ thank you for your support -I will certain post more frames. You are most certainly correct with the expression.

At least I found this for the Ioniq 5 (which should be a close relative):

@meatpiHQ So there it is, in the sceond from last frame!

meatpiHQ commented 5 months ago

@Gics78 yup this is confirmed.

For the filter you should use PID= 37 and index= 1 Expression= B2/2 Put whatever in start bit and length.

Gics78 commented 5 months ago

Filters, MQTT elm327 is disabled now grafik

Published this frame to wican/5432048f59f1/can/tx: {"bus":"0","type":"tx","ts":29200,"frame":[{"id":2020,"dlc":8,"rtr":false,"extd":false,"data":[48,0,0,170,170,170,170,170]}]} grafik

Unfortunately no answer in MQTT Explorer...

Gics78 commented 5 months ago

multi request?

meatpiHQ commented 5 months ago

@Gics78 yes. Similar to this https://github.com/meatpiHQ/wican-fw/discussions/86

Note that this frame that you mentioned is not the actual PID request, it's a response from WiCAN that tells the ecu that you're ready for muli-frame response

{"bus":"0","type":"tx","ts":29200,"frame":[{"id":2020,"dlc":8,"rtr":false,"extd":false,"data":[48,0,0,170,170,170,170,170]}]}

Gics78 commented 5 months ago

Okay, so will go back to logging in CarScanner and find the actual PID request. Then I will try to send the two requests from a script and hopefully will get a reasonable answer back.

BTW: as it seems that I get the whole of the BMS via the multiframe I might as well set up some other filters to get the most of it. Thank you again- I could not succeed without your great support!
