STM32CubeMX will not allow enabling IGMP.

[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?

Hi @paulrbryson (Community Member)​ 

Try to read this Parameter description:

You should:

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