可以考虑使用 RTOS-AT 的 AT 固件看看~

否则,你可以自己调试 LwIP 里的 dhcp,看看为什么没有获取到 IP 地址,有可能是某些 DHCP options 没有开导致。

Re: Cannot establish MQTT Connection
Hi, which scheme do you config in your AT+MQTTUSERCFG command. As the doc said here: https://docs.espressif.com/projects/esp-at/en/release-v2.2.0.0_esp8266/AT_Command_Set/MQTT_AT_Commands.html#at-mqttusercfg-set-mqtt-user-configuration <scheme>: MQTT over TLS is not supported due to memory limit on ...

Re: 关于如何将ESP-AT的AT串口通信改为DMA方式
ESP-AT 当前还不支持这样玩哎。
不过你可以试试 SDIO 方式,下面也是 DMA。参考:https://docs.espressif.com/projects/esp ... guide.html

Re: esp - idf 能否 和AT command 一併使用?
STM32 发送 AT+RST 命令后。
一方面,如果 ESP32 设置了开机重连(AT+CWRECONNCFG 和 AT+CWAUTOCONN) Wi-Fi,则 ESP32 重启后,会主动上报 WIFI CONNECTED 和 GOT IP,或者 WIFI DISCONNECT。
另一方面,STM32 也可以发送 AT+CWSTATE 命令来查询 Wi-Fi 状态,发送 AT+CIPSTATE 命令来查询 TCP/UDP/SSL 连接状态。
可以 STM32 测来主导 ESP32 行为。

Re: Is It possible to modify an AT command? CIPSEND
it seems you are using the deprecated NONOS-AT, you can refer to https://github.com/espressif/ESP8266_NONOS_SDK/blob/master/examples/at/user/user_main.c#L147, and define your CIPSEND command. This might be a little bit difficult for beginners. Or consider to use ESP32-C2, ESP32-C3, ESP32 chip, which...

Re: 关于如何将ESP-AT的AT串口通信改为DMA方式
可否详细描述下?ESP32 端 AT 串口接收改为 DMA 方式,是什么意思呢?怎么 AT 的接收,可以减小 MCU 端负荷呢?

Re: 编译AT 失败
和 https://www.esp32.com/viewtopic.php?f=3 ... 67cb3b686c 类似,请按照文档,安装 ESP-IDF CMD 4.3 的环境,不是 4.4 的。
