Cannot enable IGMP in STM32CubeIDE.

[paulrbryson]

I am using a a very recent version of STM32CubeIDE (Version: 1.3.1) and STM32CubeMX (5.6.1.202004052303). I created a new project for the Nucleo-F207ZG board.

I have enabled LWIP and then enabled UDP but the "IGMP module" has no "enabled" option. Is there some dependency that I am missing?

Can anyone else enable IGMP?

Probably just one of those things where the code can support something, but it isn't built into STM32CubeIDE (yet).

Hi @paulrbryson​ 

Try to read this Parameter description:

You should:

1. Enable "    LWIP_MULTICAST_TX_OPTIONS   "
2. Enable "    LWIP_IPV4   "
3. MEMP_NUM_IGMP_GROUP>1   

Best regards,

Wow thank you very much!

I had no idea that those descriptions were there. I may never have clicked on the "i" button and/or I never scrolled past the last parameter. Maybe I need a bigger screen and/or more monitors.

Also I never noticed the "Show Advanced Parameters" check box before.
