I'm trying to send and receive Unstructured Vendor Defined Messages with the ST USB-PD stack but there is very little information in the documentation about the API.I have found that I need to call USBPD_PE_UVDM_RequestMessage after which the stack w...

This is just a test. Has anybody else been unable to submit questions? I keep getting a red error message.

I'm using a Cube IDE generated project (latest version) with the latest version of the G0 SDK. This problem originally showed up on a custom board but I have reproduced the problem using a Nucleo-G071RB dev board wired up to a USB-C breakout jack wit...

This thread is a new problem discovered while investigating a different USB-PD issue in another thread. @Yohann M. recommended that I create a new thread for this issue. Here is the link to the other thread: https://community.st.com/s/feed/0D53W0000...

Thanks, that worked great. I stupidly assumed it would be under the regular Edit command and didn't notice the separate Edit Topics option. Excellent UI design, as always...

That's a good idea, but I don't see the topic field when I edit a post after submitting it. Am I just missing something obvious?

After a little more tinkering, it looks like the error is caused by selecting any topic for the post. The post works if no topics are entered. Weird bug.
