USB PD: Vendor_Defined_Extended Message

[DDesr.1]

Hi Community!

We're working with an STM32G0B1xx MCU and using USB PD v5.0.0 library from github (https://github.com/STMicroelectronics/stm32-mw-usbpd-core).

I see here that USBPD_EXT_VDM = 0x1E is defined properly. However, when I use this with USBPD_DPM_SendExtendedMessage(), I get a generic "USBPD_FAIL" response, and nothing gets sent out on the CC line.

So, my question is: Does the v5.0.0 library support Vendor_Defined_Extended message? 

Thank you for the support!

Hello @DDesr.1 ,

Do you mean the call to USBPD_PE_SendExtendedMessage() returns USBPD_FAIL ?
If so, it is expected as Vendor_Defined_Extended messages are not supported in v5.0.0 of USBPD Core library.
