We do not have example project on ethernet-wifi bridge. You can consider using TCP for data transmission across interface. You can first set up a TCP client on STA interface on 43907 and set up a TCP connection over STA with your TCP server. You can then set up a TCP server on ethernet interface on 43907 and listen over a TCP port. With this setup, your TCP client device will send data over ethernet to WICED TCP server. The TCP data packet handle will be received by the server using wiced_tcp_receive() and data buffer will be obtained from this handle using wiced_packet_get_data(). WICED TCP server will create a TCP packet for this data and send this packet over STA to TCP client.
