AT+GSLP: Enter Deep-sleep mode. Your project instantly has network connectivity (and a few other tricks too!). When ESP32 works as a TCP server, multiple connections should be enabled by AT+CIPMUX=1 command, because in most cases more than one client needs to be connected to the ESP-AT User Guide . ESP32 can transmit AT commands through UART and SDIO. Thus, a fully formed AT command for sending data to By default, ESP-AT uses two UART interfaces as AT ports: one is to output logs (named as log port below) and the other to send AT commands and receive responses (named as command port below). Generic AT command has four types: AT+<CommandName>=? Query the Set Commands’ internal parameters and their range of values. 1: Restart ESP32-C3 and the chip enters firmware downloading mode. Test Commands: The Test AT Commands of ESP8266 WiFi Module are used to get the parameters of a command and their range. In the project configuration during the fifth step, make the following selections (Each item below is independent. Note If you want to achieve the firmware download, you could send this set command to let ESP32-C3 enter the download mode, so that you can save Boot pins on the hardware. 0: Restart ESP32-C3 and the chip enters normal running mode. WIFI GOT IP. - ESP32-STM32-AT-Command-Interface/README. Command: Response: Command: Espressif SoCs serve as add-on modules, easily integrating wireless connectivity into existing products. Therefore, before getting into AT commands, make sure that you can reliably send and receive text. You can use a mobile phone or computer to connect to the SoftAP of or you can query the current SoftAP IP address by command AT+CIPAP?), open the Wi-Fi provisioning interface, <time>: The duration when the device stays in Deep-sleep. ESP-AT provides a wide range of AT commands with different functions and The default firmware does not support web server AT commands, With the web server, mobile phone or PC is able to control ESP32’s Wi-Fi provisioning service.
