- 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
randomization is good in cases where the previous port is not yet
released by the OS or the server hangs
On OS X it's very noticeable if you need to OTA twice in a short time.
- 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.
Proper error handling in the uploading python script
Much faster OTA example sketch with better results
New Update class that simplifies updating the firmware from any source
Updated Esp.updateSketch() to use the new class
