How to check ACK'ed tcp data when using AT+QSSLSEND

Dear All,

We use EG912 module in a project with internal TCP/IP stack. We have no ack mechanism in application layer so we need to check TCP ACK received. When we don’t use TLS we can check with AT+QISEND=sock_id,0 command; how much data sent and how much got ACK. But when we use TLS with AT+QSSLSEND=sock_id,0 we got error. How can we check ACK’ed data with TLS?

Best Regards

I think you can configure the TCP server to respond to the received data and send it down to the terminal

Dear Herbert,

Thanks for your reply. You are right but server software is not our control and we have no chance to change it.

Best Regards
