- Fixes WiFi not being able to reconnect after SDK update (#4398)
- Fixes increased current in light sleep mode
- Fixes return value documentation for wifi_{get,set}_country
- Update SDK header files and libraries to SDK 2.0.0 plus 2.0.0_16_08_09
patch
- Remove mem_manager.o from libmain.a (replaced with umm_malloc)
- Disable switch from DIO to QIO mode for certain flash chips (saves
IRAM space)
- Add user_rf_cal_sector_set; it points to rf_init_data sector.
- Change the way rf_init_data is spoofed.
This is now done by wrapping spi_flash_read and returning the data we
need during startup sequence.
- Place lwip library into flash using linker script instead of section
attributes (saves IRAM space)
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.
-------------------------------------------
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.
espressif:
Here is a patch based on SDK_v1.1.0 resolved issues below:
1. SDK 1.1.0 may boot fail if SPI Flash speed is 80MHz.
2. Memory Leak in libssl when SSL connection fail.
3. Update smartconfig, please using it with the latest Espressif APP https://github.com/EspressifApp
Sorry for the inconvenience.
