MQX tcp send fails with socket error

[deepaappu]

Hi,

I'm currently working with K66 controller and MQX5.0. I'm facing an issue with socket send. For secured periodic MQTT send, the device calls send() and fails with an error SOCKET_ERROR. Is there is way to flush the data in the TCP buffer and try again?

Best regards,

Deepa

As far as I know, only shutting down the stream socket with an abort operation can discard the socket's internal buffers immediately.
