Release Notes
This patch is based on the ESP8266_NONOS_SDK_V1.5.2. When this patch is used, .a files in this patch shall replace corresponding files under the SDK/lib Folder.
  1. Resolved an issue that RF_Init_data sector may be broken in stress test. Provided a function “user_rf_cal_sector_set” which has to be added in application by software developer. More details about user_rf_cal_sector_set refer to documentation “2C-ESP8266__SDK__API Guide”.(Resolved in ESP8266_NONOS_SDK_V1.5.2.1)
  2. Isolated cases of rf failure after external reset have been debugged.(Resolved in ESP8266_NONOS_SDK_V1.5.2.1)
  3. Modify 112 byte of esp_init_data_default.bin, 0x03->0x00, turn off auto freq correction. (Resolved in ESP8266_NONOS_SDK_V1.5.2.1)
Attention: Please refer to “user_main.c” in the folder for “user_rf_cal_sector_set” sample code.

  1. esp_init_data.bin has to be downloaded into flash at least once.
  2. Download blank.bin to initialize the sector stored RF_CAL parameter (set by user_rf_cal_sector_set), and download esp_init_data.bin into flash, when the system needs to be initialized, or RF needs to be calibrated again.

AT Note:
  1. Since the release of ESP8266_NONOS_SDK_V1.5.0, AT firmware is too large to use 4Mbit flash. Please choose flash with at least 8Mbit capacity.
  2. Firmware upgrade over-the-air process is changed a bit. We will upgrade the latest AT firmware to Espressif Cloud server only after it has been tested and the overall performance is guaranteed. Users may not be able to use AT+CIUPDATE in ESP8266_NONOS_SDK_V1.5.0 and other more advanced versions.

Have fun!



    以下是 SDK 的相关下载链接 (版本 ESP8266_NONOS_SDK_V1.5.2.1_patch_20160704):
  1. 下载ESP8266_NONOS_SDK_V1.5.2
  2. 文档下载链接
  3. 您可以继续参与 Bug Bounty 计划

  1. 修正部分情况下,RF_Init_data 系统参数区可能被破坏的问题。新增 user_rf_cal_sector_set,用户程序必须实现此接口,详细参见文档 “2C-ESP8266__SDK__API Guide”。 (中解决)
  2. 修正外部复位后,小概率存在 rf 不工作的问题。(中解决)
  3. 修改esp_init_data_default.bin的112字节,0x03->0x00,默认关闭频偏自动校正。(中解决)

ESP8266_NONOS_SDK 注意事项:
  1. esp_init_data.bin 至少需要烧录一次到 flash。
  2. 建议整个系统需要做初始化设置时,或需要重新进行 RF_CAL 时,烧录 blank.bin 到 RF_CAL 参数区 (由 user_rf_cal_sector_set 设置),并烧录 esp_init_data.bin 到 flash。

AT 注意事项:
  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。
