title: Lwip UDP and UART
body: <p>LWIP library version - 2.1.2
  Atmel Studio - version 7.0
  Demo code - THIRDPARTY_LWIP_RAW_BASIC_HTTP_EXAMPLE
  Target device - ATSAME70Q21
  Dev Board - ATSAME70- Xplained
  Compiler - GCC</p>
  
  <p>We are trying to send/receive data to the controller through Uart and UDP.</p>
  
  <p>In the mainloop, we are sending udp data to the PC by calling ass_udp_send().</p>
  
  <p>And we are sending data from PC to controller through UART.</p>
  
  <p>Issue - PC receives the UDP data sent by the controller. Once the PC sents data through UART, PC stops receiving the udp data sent by controller.
  Control reaching ass_udp_send() function but data is not received on PC side.</p>
