Currently the library only works on STA interface, AP interface is not supported.
See attached example and library README file for details.
#### DNS server (DNSServer library) ####
Implements a simple DNS server that can be used in both STA and AP modes. The DNS server currently supports only one domain (for all other domains it will reply with NXDOMAIN or custom status code). With it clients can open a web server running on ESP8266 using a domain name, not an IP address.
See attached example for details.
#### Servo ####
This library exposes the ability to control RC (hobby) servo motors. It will support upto 24 servos on any available output pin. By defualt the first 12 servos will use Timer0 and currently this will not interfere with any other support. Servo counts above 12 will use Timer1 and features that use it will be effected.

esp_iot_sdk_v1.1.1_15_06_05 Release Note
-------------------------------------------
Resolved Issues（Bugs below are eligible for Bug Bounty Program):
1.Too short timer which set by os_arm_timer_us may cause crash. [Tommy]
2.Call os_malloc in low heap situation may cause crash. [MeneerThijs]
3.Memory leak issue when SSL connection fail. [孙新虎]
Optimization:
1.Update JSON parser to handle with illegal parameter and illegal calling progress.
2.Add parameter of user_esp_platform_check_ip in user_websever.c which in IOT_Demo.
3.Update UART driver to solve the problem that if send data through UART while ESP8266 startup may cause UART invalid.
4.Update smartconfig to version 2.2, corresponding phone APP v0.3.2. And update the description and example of smartconfig_start in document "2C_ESP8266__Programming Guide"
5.Update code in iram to solve the problem that space for text is not enough.
6.Update PWM driver and provide libpwm.a in esp_iot_sdk, update PWM APIs in "2C_ESP8266__Programming Guide", more details in "Added APIs" below.
7.Revised issue that multicast may fail in ESP8266 softAP mode.
8.Update folder "driver",add folder "driver_lib" in \esp_iot_sdk\examples , add "hw_timer.c" about frc1 hardware timer.
9.Remove useless driver code in IOT_Demo
10.Update IOT_Demo to use the latest PWM driver in light demo.
11.Provide liblwip_536.a of which MSS size is 536
12.Revised issue that boot may fail when 80Mhz SPI clock selected
13.Update esp_init_data_default.bin about RF option in \esp_iot_sdk\bin
Added APIs：
1.PWM APIs：

（1）system_param_save_with_protect：write data into flash with backup protection
（2）system_param_load：read data which saved into flash with backup protection
3.system_get_rst_info：get information about current startup，it is a normal startup or watch dog reset
4.at_response：set AT response
5.at_register_response_func：register a callback for user-define AT response.
6.Update document "2C_ESP8266__Programming Guide" to add description of interrupt definition in ets_sys.h
AT_v0.25 Release Note:
Note: For AT firmware to support FOTA, flash size need to be 1024KB or more than that.
Optimization:
1.Add parameter about UDP local port in command "AT+SAVETRANSLINK"
Added AT command：
1.AT+CIPDINFO：set configuration whether show remote IP and remote port with “+IPD” or not
esp_iot_sdk_v1.1.0_15_05_27_p1 Release Note
