Hello, we are using Nuttx on our Robot Control Boards, and we are seeing an odd behavior when communicating with our main board that is running Linux.
Every once in a while, we see a more than a 1 second delay when we call Socket::Send to send information to the Main board. Using Debug Statement, I confirmed that we are calling Socket::Send in a timely manner. Also. by using WireShark, I can confirm that the message does not get sent out until more than a 1 second later. Strangely, after adding an option to the socket for a 300ms send Delay "SO_SNDTIMEO", we don't see the Delay in communication anymore. Also Strangely, we reduce the timeout to 1us and we don't see any timeout happening in the socket. Why would adding "SO_SNDTIMEO" remove the once in a while delay we were seeing and why after setting the timeout to 1us we are not seeing the timeout error? best, Hakeem _____________________________________________________________________ This email message, including any attachments, may contain confidential and proprietary information for the sole use of the intended recipient.
