get IP address 0.0.0.0

[ftdiyun]

Hi,

For AT firmware, if we enabled DHCP mode after connected to AP. Using "AT+CIFSR" command, we could get IP address of "0.0.0.0" sometimes. It is not always happening, but we could see it around 2/10 times.

Is there any bug to cause this problem? I am using the latest firmware, but in old firmware, I could also see it also.

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
