No frame when I debug socketcan out

[David321]

Hello,
I'm working on a project that uses the socketcan out, to visualize frames coming from a BMS (Battery Management System). So far when I debugged the socketcan out I was able to see the frames, but due to a problem I don't know I'm not getting any frames when I debug.

Has anyone had this problem before?
Thanks for your help

Hi @David321

What version of socketcan are you using? Is it node-red-contrib-socketcan?

Are the messages sent to the bus at all? We currently do have some issues with NMT messages. For example 000#8101 (reset node 1) does not work at all.

In terminal: cansend can0 000#8101 on the other hand works.

Edit: Oddly, if I create a new simple flow, everything works as expected

Okay, found the problem thanks to you The wire to the socket-in was not connected.
Looks good, right?

But if I move the node a bit (oops):

Anyway .. if you share some bits of your flow, we can have a look.
