Other Parts Discussed in Thread: CC3300

I need some support in DHCP Lease Timeout concepts:

1. I have got an IP address Dynamically.

2. I am connected to the required server, but my connection gets closed after 1.05 hour,

3. CC3300 module will be sending data to server every 3 minutes, and module receives Acknowledgement from Server each time without fail,

4. Under such condition the Server Connection get closed after 1 hour or so.

5. I have used netapp_timeout_values( 0, 3600 secs, 10 secs, 3600 secs), -->( DHCP time is 0, and Socket Inactivity as 1 hour).

6. Does my socket gets hanged/ closed bcos of socket inactivity state, or bcos of DHCP lease issue. Might not be because of Socket Incativity since i am sending data every 3 mins.

7, Should I manually renew the DHCP lease timeout if i am acting as a client.

Thanks

Amit,

The cc3000 will request an IP address automatically after the lease has expired. Do you see DHCP discover packets sent by the CC3000 after the timeout.

The default timeout of DHCP is 14400 seconds.

aucDHCP DHCP lease time request, also impact the DHCP renew timeout. Range: [0-0xffffffff] seconds, 0 or 0xffffffff == infinity lease timeout. Resolution: 10 seconds. Influence: only after reconnecting to the AP. Minimal bound value: MIN_TIMER_VAL_SECONDS - 20 seconds. The parameter is saved into the CC3000 NVMEM. The default value on CC3000 is 14400 seconds.

If you set the default do you still lose the connection?
