udp_bind() cannot receive broadcast.

Question

Hello, 
 I am implementing firmware to communicate using UDP between two nRF7002. 
 The sender does not know the IP address, so it tries to know the IP address of the receiver using broadcast. But udp_bind() ignores the broadcast for some reason. 
 It is correct because udp_bind() can receive using unicast. 
 Is it a specification that broadcasts cannot be received? Or is it not implemented yet? 
 Best Regards, Yoshihiro Goto

Hi, 
 > bind() to ANY address instead (0.0.0.0), that should make the socket receive all packets for the port which get through the IP layer, 
 Thank you for info. I can receive a broadcast packet using udp_bind() with (0, 0, 0, 0). And I look forward to the implementation of broadcast reception.
