How to get connected AP's IP address (gateway address)

Postby ftdiyun » Fri Jul 29, 2016 9:23 am

We are using ESP8266 as a station,AT+CWMODE=1,
After connecting to AP, and obtained the address, there is no information of AP's IP address.
AT+CIFSR
+CIFSR:STAIP,"192.168.1.5"
+CIFSR:STAMAC,"18:fe:34:a6:01:a9"
OK

If there is no AT commands to know AP's IP address, please suggest which API in the SDK we can use. In "2c-esp8266_non_os_sdk_api_reference_cn.pdf", there seems no API to provide AP's IP address.

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

It seems that I replied a same question once. You could try
Using API : WiFi event "EVENT_STAMODE_GOT_IP" after registered callback by wifi_set_event_handler_cb.
Using AT command : AT+CIPSTA_CUR?

Hi, I am not using static IP. I am using WPS mode, so I could not know the connected AP's IP in advance, like you mention "AT+CIPSTA_CUR".

For the call-back function, could you elaborate more in detail. Finally, what's the API can user use to get the AP's IP?

Anyway, "AT+CIFSR " could not return the connected AP's IP. This should be a bug, and needs to be corrected.

In fact, I did not try it, but I think it can work. Maybe you could try it.
Using API, documentation "2c-esp8266_non_os_sdk_api_reference" has sample code of wifi_set_event_handler_cb.
Using AT command, after ESP8266 connected to an AP, input command: AT+CIPSTA_CUR? to get the IP details of ESP8266 station. Do NOT forget the ? character in the command (AT+CIPSTA_CUR?), it is used to query the information.

I don't have a working module with me now, I will try your recommended commands after that, hope it works, my mode is station mode, and getting IP using WPS.
