please unzip the attachment, rename them and replace "libsmartconfig.a".

Add sending the UDP packets as "ACK" after connected to AP
smartconfig_v0.7.rar

Thanks pvvx for bug reporting

This patch fixed:
1) system_print_meminfo(); heap size printf error
2) uint8 beacon_interval; change to uint16

please unzip the attachment, rename them and replace "user_interface.h" and "libmain.a"

Thanks for your interest in ESP8266 ! ;)

请勿使用本旧版本 SDK，建议使用 最新发布 SDK。

esp_iot_sdk_v0.9.5_15_01_22 Release Note

AT becomes a lib attached to esp_iot_sdk.
Programming guide in “document” shows APIs for user to define their own AT commands.
AT bin files are in \esp_iot_sdk\bin\at，please pay attention to the “readme.txt”.

Fix bugs:
1、Incorrect status got by API : wifi_station_get_connect_status；
2、Sniffer can not quit without restart；
3、wifi_station_ap_change always return true；
4、TCP connection issues

Add APIs:
1、system_deep_sleep_set_option: set what the chip will do when deep-sleep wake up；
2、wifi_status_led_uninstall；
3、wifi_station_ap_get_info : get information of AP that ESP8266 station connected.
4、wifi_station_dhcpc_status & wifi_softap_dhcps_status ： get DHCP status
5、smart config APIs, more details in documents.
6、add beacon_interval parameter in struct softap_config
7、espconn_recv_hold and espconn_recv_unhold to block TCP receiving data and unblock it.
8、AT APIs to let user define their own AT, more details in documents.

Optimize：
1、light sleep、modem sleep、deep sleep
2、compile method：./gen_misc.sh ，then follow the tips and steps.
3、when no buffer for os_malloc，return NULL instead of malloc assert.
4、users can enable #define USE_OPTIMIZE_PRINTF in user_config.h to remove strings of os_printf from ram to irom
5、faster the re-connection of ESP8266 station to router after deep-sleep.
6、update to boot v1.2 to support new format user.bin；
7、update ARP
8、update SSL
9、revised system_deep_sleep，system_deep_sleep(0)，set no wake up timer，connect a GPIO to pin RST, the chip will wake up by a falling-edge on pin RST


AT 不再单独 release，而是作为 esp_iot_sdk 的库
document 文件夹中的编程手册说明 API， 用户可自定义 AT command
AT bin 位于 \esp_iot_sdk\bin\at ，请注意 readme.txt

解决问题:
1、wifi_station_get_connect_status在某些情况下返回错误状态的问题；
2、Sniffer 无法退出必须重启；
3、wifi_station_ap_change 总是返回 TRUE；
4、TCP 连接的一些问题

新增接口:
1、system_deep_sleep_set_option: 设置 deep sleep 醒来后的行为；
2、wifi_status_led_uninstall；
3、wifi_station_ap_get_info : 获取 ESP8266 station 连接过的 AP 信息.
4、wifi_station_dhcpc_status & wifi_softap_dhcps_status ：读取 DHCP 状态；
5、smart config APIs，具体请参见说明文档。
6、在结构体 softap_config 中新增 beacon_interval 参数
7、espconn_recv_hold and espconn_recv_unhold ：阻塞 和 停止阻塞 TCP 收包.
8、AT系列接口，让用户可以自定义 AT 指令。具体请参见说明文档。

优化：
1、修改部分休眠策略，light sleep、modem sleep、deep sleep，减小电流；
2、修改Makefile、ld及生成bin的流程，编译指令：./gen_misc.sh ，根据提示输入参数.
3、修改os_malloc，当分配不到内存时返回NULL，不再 assert；
4、内存优化，重新定义os_printf，将字符串置于irom段，如需使用优化后的os_printf，请在user_config.h中定义USE_OPTIMIZE_PRINTF；（采用irom换dram的方式，但会增加irom的用量 ）
5、优化deep sleep 醒来后 station 连接流程，缩短 station 连入路由需耗时间；
6、更新boot v1.2，支持新格式的user.bin；
7、更新 ARP
8、更新 SSL
9、修改system_deep_sleep接口，支持设置为0，永远不醒，可通过外部GPIO拉低RST脚进行唤醒

Thanks for your interest in ESP8266 !
