Re: AT指令从“=”这个等于号开始只能传125BYTE的数据

你好,

非常抱歉,这个长度限制无法修改。

但是你可以使用 void at_register_uart_rx_intr (at_custom_uart_rx_intr rx_func) 自行处理 UART0 RX 的数据。
例如,AT+xxxx 使能 at_register_uart_rx_intr,之后接收到的数据都是给这个命令的,等接收完并处理之后,再恢复到原状,切换 UART0 RX 给 AT 使用。请知悉。

感谢你对 ESP8266 的关注!

Re: ESP-WROOM-02 migration to ESP-WROOM-02D

Hi, Sorry that we cannot reproduce your problem. Does it only happen on a specific ESP-WROOM-02D? Or every ESP-WROOM-02D has the same problem? Please note that the power supply should be 300mA at least, it is suggested to provide more than 500mA power supply. Thanks for your interest in the ESP8266!

Re: +IPD adding linebreaks?

Hi,

+IPD will not add any data into the original data received from internet.
It should be your original data has the line break.
Or you can test it with any TCP tool on your PC to check if there are still line breaks.

Re: ESP CAN NOT ACCESS TO SERVER ??

Hi,

You need to wait till the command "AT+CIPSTART" got an "OK" response.

If there is no "OK", please capture the TCP packets by wireshark or omnipeek, and provide the packets for debugging.

Re: Does anyone have an HTTPS server running?

Hi,

Please have a try with the ESP8266_NONOS_SDK commit a1fa90.

And add espconn_tcp_set_max_con(1); on your demo.

If your problem is still unsolved, please feel free to let us know.

Thanks.

Re: Wrong SPI Flash Size

Hi,

While download the firmware into flash, you need to select the corresponding flash map on the ESP Flash Download Tool.

Re: esp8266 used as TCP server,客户端连接后再断开,这样反反复复5次,第6次就再也连不上了

你好,

非常抱歉带来误解,我们在示例中有说明是针对 ESP8266 non OS SDK 的。

目前补充了示例说明,如果是 ESP8266 RTOS SDK 需要调用 espconn_init 初始化 espconn。

感谢你的反馈!

Re: esp8266 used as TCP server,客户端连接后再断开,这样反反复复5次,第6次就再也连不上了

你好,

TCP 默认最多支持 5 个连接。从问题描述看来,是否客户端未能正常断开连接?
可以看打印信息,是否走到了 disconnect callback 中进行查证。

Re: Bug in FW ESP8266_NO_OS_KRAK

Hi,

x,CONNECT FAIL means the connection fail to be established.

Could you provide the entire test steps so that we can test it exactly as your way to reproduce your problem?

And could you capture the packets by wireshark for debugging?

Re: WiFi scanning active or passive?

Hi,

The WiFi passive scan has been added in the ESP8266 non OS SDK https://github.com/espressif/ESP8266_NONOS_SDK.

And we will add it into the future ESP8266 RTOS SDK release too.

Thanks for your interest in ESP8266!
