Is there a possibility to change the keep_alive interval? The interval seems to be set by a value of 2 hours. For my porpuse this is too long. Matthias

Yes the time you have identified is correct. It is 2 hours however this set by the stack and is exposed to end users to be modified since it needs the stack to be rebuilt.

Currently, we have a new API to change keep alive time. int NASetTCPKeepaliveTimer(unsigned long keep_alive_timeout); If you do not have this API in your version stack, please contact technical support at Netsilicon Inc…
