get IP address 0.0.0.0

When we switch from station mode to DHCP mode. We disconnect the connection already.
We check the connection station using "AT+ CIPSTATUS", and it returns "2", means "Got IP". However, when we use "AT+CIFSR", it returns:
+CIFSR:STAIP,"0.0.0.0"
+CIFSR:STAMAC,"18:fe:34:a6:01:a9"
OK

Be noted that you need read immediately after "AT+ CIPSTATUS" returns "2", to reproduce the problem.

FW version:
at+GMR
AT version:1.3.0.0(Jul 14 2016 18:54:01)
SDK version:2.0.0(656edbf)
compile time:Jul 22 2016 12:02:54
OK
