    udp multicast STA breaks when AP  is enabled

    clutech

      Hello,

       

      I have an udp multicast running on the STA interface, this is running without any problems.

       

      However at the moment I enable the AP interface the UDP send function returns an error (code 15) and is unable to send my UDP packet.

      I have also tried to disable my mutlicast functionality before I enable the AP en enable it again after the AP is up, but this won't work either.

       

      The UDP multicasst udp packets are still received when enable the AP, only the sending back seems to go wrong.

      Could it be that it tries to send the reply back over the AP network instead of the STA network?

       

      I am using LWIP.

       

      Cheers,

      Gerard
