I have to correct myself. Either I did not remember correctly (has been some months now) or it is due to the rebase, but without using posix sockets it is not working at all. I traced it back to the function `sys_arch_mbox_fetch` at `pkg/lwip/contrib/sys_arch.c` which is repeated a few times and then gets stuck for some reason. I agree it is dirty, I should have mentioned that this is one of those hacks that should be removed in the end ;) But I needed this for now in order to proceed with the wolfmqtt port.
I pushed a throwaway commit to #15969. In the file `dns.c` you will find the line `#define USE_POSIX 0` where you can switch between the original module and the posix extension. Any idea what could cause this?
