Here are the links for this SDK release (version ESP8266_NONOS_SDK_V1.5.1_16_01_08):
  1. Download Related Documentation
  2. Bug Bounty Program

Release Notes
Resolved Issues(Bugs below are eligible for Bug Bounty Program):
  1. Returned value of system_get_rst_info is wrong.
  1. Optimize the data receiving process under TCP connection.
  2. Optimize low MAC and increase stability of the software.
  3. Optimize watchdog feeding process.
  4. Optimize softAP working mode so that some stations can be easily connected.
  5. Optimize station working mode, enabling connection even when the SSID of the AP has changed.
  6. Optimize station working mode, and increase router’s compatibility during the connection process.
  7. Optimize SSL shakehand.
  8. Optimize espconn internal timer.
  9. Optimize UDP transmission.
  10. Improve the flash writing process.
  11. Strenthen WPA2 security protocols.
  12. Improve data sending ability.
  13. Straighten the control capability of GPIO16 under light sleep mode.
  14. boot.bin is updated to version 1.5, resolving boot failure when firmware is upgraded over the air (OTA).

AT_v0.52 Release Note:
  1. With the release of NONOS SDK Version 1.5.0 (ESP8266_NONOS_SDK_V1.5.0), the space that AT commands occupies has increased to more than 4Mbit. Therefore, flash with 512Kbit capacity is no longer supported. Please choose flash with at least 8Mbit capacity.
  2. Firmware upgrade over-the-air process is changed a bit. We will upgrade the latest firmware to Espressif Cloud server only after it has been tested and the overall performance is guaranteed. Users may not be able to download firmware encapsulated in ESP8266_NONOS_SDK_V1.5.0 and other more advanced versions.
AT_v0.52 Release Note:
  1. Optimize the process of establishing TCP server via AT command.
  2. Optimize UART-WiFi transparent transmission mode via AT command.

Have fun!

  1. 文档下载链接
  2. 您可以继续参与 Bug Bounty 计划

修正问题(符合乐鑫 Bug 赏金计划):
  1. espconn_abort 会导致系统崩溃的问题。
  1. 优化 TCP 收包流程。
  2. 优化 low mac,增强软件稳定性。
  3. 优化软件看门狗喂狗行为。
  4. 优化 ESP8266 softAP,修正部分 station 连接过程不稳定问题。
  5. 优化 ESP8266 station,修正 AP 更改 SSID, ESP8266 可能连接的问题。
  6. 优化 ESP8266 station,修正连接路由器的兼容性问题。
  7. 优化 SSL 握手流程。
  8. 优化 espconn 内部定时器。
  9. 优化 UDP 传输。
  10. 优化写 Flash 的流程。
  11. 优化 WPA2。
  12. 优化 freedom send 流程。
  13. 修正 GPIO16 在 light sleep 模式下的控制问题。
  14. boot.bin 更新到版本 1.5,修正升级后可能启动失败的问题。

AT_v0.52 Release Note:
  1. 从版本 ESP8266_NONOS_SDK_V1.5.0 起,AT 固件所需空间增大,无法再使用 4Mbit (512KB) Flash,请使用 8Mbit (1MB) 或以上容量 Flash。
  2. 我司优化了 AT 固件的升级流程,AT 固件发布后,会等一段时间,待客户反馈稳定后,才上传到 Espressif Cloud 以供下载更新。因此,如果使用 ESP8266_NONOS_SDK_V1.5.0 及之后版本的 AT 固件暂时无法从 Espressif Cloud 升级。
AT_v0.52 更新说明:
  1. 优化 AT TCP server 流程。
  2. 优化 AT 透传流程。
