esp_iot_sdk_v1.5.1_16_01_08 Release Note
----------------------------------------
Resolved Issues (Bugs listed below apply to Bug Bounty Program):
1.espconn_abort may cause system crash.
Optimization:
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 upgrade to version 1.5, resolving boot failure when firmware is upgraded over the air (OTA).
AT release note：
1.Optimize the process of establishing TCP server via AT command.
2.Optimize UART-WiFi transparent transmission mode via AT command.
Please be noted that 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.
Please be noted that 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.
- free up some memory by getting rid of intermediate buffer
- libaxtls: update to 6830d98
- allocate plaintext buffer in two stages: 4*MSS initially, grow to 16k after handshake
- free certificate data after handshake is complete
- preallocate some structures to reduce memory fragmentation
- use new AutoInterruptLock
- add delay to give the RTOS some time to handle TCP
WiFiClient.cpp
- add stopAllexcepted to cancel all TCP excepted one
ClientContext.h
- add getLocalPort()
ESP8266HTTPUpdate.cpp
- close all not needed TCP and UDP
osapi.h
- missing commit from SDK
----------------------------------------
Here is a patch based on esp_iot_sdk_v1.3.0 (non-OS SDK) resolved issue that if there are 2 connections, one is normal TCP connection, the other is SSL connection, it may cause memory leak.
Download and unzip the attachment, replace the lib in esp_iot_sdk/lib folder.
Please do not set the same priority for two different tasks when using system_os_task.
Sorry for the inconvenience.
Fixes issue of reentrant calls to nointerrupts()
exposed functional replacements to cli sei and SREG when dealing with
interrupts
InterruptLock class to auto stop and restore interrupt level
Fix user ISR calls to be like Arduino with interrupts disabled fully.
Here is a patch of memory optimization based on SDK_v1.2.0
1. It saved about 8KBytes memory.
2. It revised problem that change mode may cause memory leak.
3. Update SmartConfig to version 2.4.3
Please replace the lib in \esp_iot_sdk_v1.2.0\lib
Thanks for your interest in Espressif Systems and ESP8266 !
esp_iot_sdk_v1.2.0_15_07_09_p3 Release Note
-------------------------------------------
Here is a patch based on SDK_v1.2.0 solved problem that if AP’s SSID is hidden，ESPTOUCH may get wrong BSSID of AP and cause connection fail.
Please replace the lib in \esp_iot_sdk_v1.2.0\lib
Sorry for the inconvenience.
esp_iot_sdk_v1.2.0_15_07_09_p2 Release Note
-------------------------------------------
Updated libssl again. To support SHA-256 and SHA-512.
Thanks for your interest in Espressif Systems and ESP8266 !
esp_iot_sdk_v1.2.0_15_07_08_p1 Release Note
-------------------------------------------
Here is a patch based on SDK_v1.2.0 solved problem that abnormal SSL disconnection may cause reset.
Please replace the lib in \esp_iot_sdk_v1.2.0\lib
Sorry for the inconvenience.
-------------------------------------------
Here is a patch based on SDK_v1.1.2 solved problem of abnormal current during modem-sleep.
Please replace the lib in \esp_iot_sdk_v1.1.2\lib
Sorry for the inconvenience.
esp_iot_sdk_v1.1.2_15_06_24_p1.1 Release Note
-------------------------------------------
Here is a patch for AT firmware based on SDK_v1.1.2 resolved issue that AT user parameter area was located in wrong address，it may cause WiFi configuration goes wrong.
Please update to this new AT bin files and call "AT+RESTORE" to factory reset. If you call “AT+CIPUPDATE” to upgrade，please also call "AT+RESTORE" to factory reset once.
“AT_bin_v0.25_1024+KB_flash_can_upgrade.zip”
- normal AT bin，runs with boot.bin，can FOTA upgrade，need to use 1024KB flash
“AT_bin_v0.25_for_512KB_flash_cannot_upgrade.zip”
- for old version module which flash size is 512KB
eagle.flash.bin downloads to flash 0x00000
eagle.irom0text.bin downloads to flash 0x40000
can not FOTA upgrade，please don‘t call “AT+CIPUPDATE”
"SDK_v1.1.2_AT_patch_01.zip"
- libs for users who need to compile their own AT firmware，replace libs in \esp_iot_sdk_v1.1.2\lib
So sorry for the inconvenience.
