If you’re using a broadcast IP, you should be using a broadcast MAC. Use FF:FF:FF:FF:FF:FF.

When a device sends a packet to the broadcast MAC address (FF:FF:FF:FF:FF:FF), it is delivered to all stations on the local network. It needs to be used in order for all devices to receive your packet at the datalink layer.
