    (CYW943907) network_tcp_send_packet error with 0x49


      When I used network_tcp_send_packe, error 0x49 [NX_TX_QUEUE_DEPTH] is occurs.Our application sends about 25kbytes data via wi-fi(2.4GHz) at regular intervals about 160ms. This problem is happened sometimes in a few hours.

      I create the sample code based on snip.tcp_client and attached in this discussion.


      Can you give me some advice to resolve this problem?


      BTW, this problem is related to other discussion ((CYW943907) network_tcp_send_packet error with 0x39 )
