  2. * This example shows how to use WebSerial variant to send logging data to the browser.
  3. *
  4. * Before using this example, make sure to look at the WebSerial example before and its description.\
  5. *
  6. * You might want to control these flags to control the async library performance:
  7. * -D CONFIG_ASYNC_TCP_QUEUE_SIZE=128
  8. * -D CONFIG_ASYNC_TCP_RUNNING_CORE=1
  9. * -D WS_MAX_QUEUED_MESSAGES=128
