Other information

It looks like espressif/esp-idf#18489 is related. I haven’t verified by incorporating the fix diff, but setting CONFIG_BT_NIMBLE_STATIC_TO_DYNAMIC=n resolved the issue.

It looks like Espressif acknowledges this as a bug and will fix it in the ESP-IDF. If we can safely work around that before the fix is available in a release ESP-IDF, that is welcome. I don't understand the implications of adding CONFIG_BT_NIMBLE_STATIC_TO_DYNAMIC=n to the configuration – what impact would it have beyond resolving this issue. Do you know?

I don’t know the details of this CONFIG_BT_NIMBLE_STATIC_T setting either. Since there is a workaround, I think it should be fine to wait for the fix in the next ESP-IDF release.
