CYW43012 keepalive packets and TCP keepalive

[ivryc_4111716]

Hi,

I used 'mkeep_alive' option to force WiFi send keepalives packets while sleeping (I provide TCP packet which I build manually). I also found tcp keepalive option for WiFi chip (using 'tcpka_conn_add' and 'tcpka_conn_enable' options), but I got 'UNSUPPORTED' error.

The problem with 'mkeep_alive' is that it just sends data without handling connection breaks. In my case I want WiFi chip behave like usual TCP connection, i.e. send keep alive probes periodically, and if chip does not receive N answers in a row - report error. Is there any mechanism to achieve such behavior?

Thanks,

Ivan.
