All ESP32 modules use GPIO1 and The ESP32 microcontroller works double duty – handling Bluetooth audio streaming while managing voice commands, while the MAX98357A I2S amplifier ensures high-quality sound When ESP32 station is not connected to an AP, it is recommended to use this command to query Wi-Fi information; after ESP32 station is connected to an AP, it is recommended to use Introduction. In the project configuration during the fifth step, make the following selections Escape is needed in AT commands only, not elsewhere. It covers basic commands such as AT, AT+RST, AT+GMR, and [ESP32 Only] BLE AT Commands¶. Then, ESP32 enters UART-BT passthrough mode. The CWMODE command supports ESP32: Get back to SSC-command mode? 3 posts • Page 1 of 1. WiFive Posts: 3529 Joined: Tue Dec 01, 2015 7:35 am. Before setting the Light-sleep mode, it is recommended to set the wakeup source in advance through the command AT+SLEEPWKCFG, otherwise ESP devices can’t wake up and will always be in sleep mode. Then, define desired Modem-sleep mode and Light-sleep mode can be set under Wi-Fi mode or BLE mode, but in Wi-Fi mode, these two modes can only be set in station mode. More details are in Below is the example command for ESP32-WROOM-32. The message It makes an ESP32 board work as a slave, and an MCU as a host. This AT command is enabled when ESP8266 runs as SoftAP, and when DHCP is enabled. Postby aderregibus » Sat Apr 18, 2020 2:30 pm. After setting the Light-sleep mode, if the Light-sleep wakeup condition is not met, ESP32-C6 will automatically enter the sleep mode. The AT command set is divided into different categories: Basic AT commands, Wi-Fi AT commands, TCP/IP AT commands, etc. // If the target AP's SSID is "ab\,c" and the [中文] AT: Test AT startup. If the Bluetooth LE connection is established successfully, message It is strongly recommended to read the following sections for some common information on AT commands before you dive into the details of each command. This document provides detailed command examples to illustrate how to utilize ESP32 Classic Bluetooth® AT Commands on ESP32. The document is structured as follows: Release ESP-AT is a set of AT commands developed by Espressif that can be used to interface with Espressif products. AT+CIPV6: Enable/disable the network of Internet Protocol Version 6 (IPv6). CheatSheet of commands, ESP32 AT uses two UART ports: UART0 is used to download firmware and log output; UART1 is used to send AT commands and receive AT responses. ESP32 as a TCP server in multiple connections . Query Command. It is strongly recommended to read the following sections for some common information on AT commands before you dive into the details of each command. In fact, the ESP-AT project already provides the When entering the above command, replace the address with your ESP32 Bluetooth LE server address. Terminate Classic Bluetooth SPP ESP-AT project was started and powered by Espressif Systems as an official project, for the ESP32, ESP32-C2, ESP32-C3, ESP32-C6, and ESP32-S2 Series SoCs provided for Windows, Linux, and macOS. In addition, you can add some custom AT commands in at_custom_cmd like AT+CIUPDATE if necessary. In single Wi-Fi mode, only station mode supports Modem-sleep mode and Light ESP32 AT uses two UART ports: UART0 is used to download firmware and log output; UART1 is used to send AT commands and receive AT responses. It can be configured to operate as a station, connecting to an existing network, a softAP, creating its own This document introduces the ESP32 AT commands, and explains how to use them. For example, when AT command port prints > and wait for your input, the input does not need to be escaped. When the packet which only contains +++ is received, the device returns to normal command mode. Please refer to ESP-AT Versions for more details。 Resources. If you need to modify the commands supported by ESP32 by default, please compile the ESP-AT project by following the steps in Compile ESP-AT Project Locally documentation. The modem device is modeled with a DCE (Data Communication Equipment) object, which is composed of: The reason for that is that ESP32’s UART is interrupt driven, so while performing computational Before setting the Light-sleep mode, it is recommended to set the wakeup source in advance through the command AT+SLEEPWKCFG, otherwise ESP32-C6 can’t wake up and will always be in sleep mode. This guide provides practical examples with code, code explanation, and circuit diagrams. Set Command. [中文] This is the documentation for ESP-AT Development Framework. boot: chip revision: 0 I (33) boot. AT+GSLP: Enter Send AT commands while in PPPoS connection. There are several guides for For example, command AT+SYSFLASH=0,"mfg_nvs" can erase the entire "mfg_nvs" user partition. Some of them can only work on the ESP32 series, so they are marked as [ESP32 Only] at the beginning; those without any mark can By default, UART0 (TXD0 is GPIO1 and RXD0 is GPIO3), connected to the USB bridge chip, acts as debug interface. <data_len>: the length of the data which was ready to send. If you need to modify the commands supported by ESP32-C2 by <mode>: 0: Restart ESP32-C2 and the chip enters normal running mode. // If the target AP's SSID is "abc" and the password is "0123456789", the command should be: AT+CWJAP="abc","0123456789". Before you run any Ethernet AT commands, please make sure TCP-IP AT Commands [ESP32 Only] Bluetooth® Low Energy AT Commands [ESP32 Only] Bluetooth® AT Commands; MQTT AT Commands; HTTP AT Commands [ESP32 Only] This document provides detailed command examples to illustrate how to utilize HTTP AT Commands on ESP32.

AT + CWJAP = "comma\,backslash \\ ssid", "1234567890" AT + MQTTPUB = 0, "topic", " \" ESP-AT received the data from the network when AT is not in Passthrough Mode. Parameter: <conn_index>: index of classic bluetooth SPP connection; only 0 is supported for the single connection right now. If the operator is write, AT Command Set¶ Here is a list of AT commands. AT+GMR: Check version information. This document provides a detailed introduction on how to add user-defined AT commands. This command is used to set the WiFi Mode of operation as either Station mode, Soft Access Point (AP) or a combination of Station and AP. Basic AT Commands. 0. 1: Restart ESP32-C2 and the chip enters firmware downloading mode. This command is supported since ESP-AT v2. 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 ESP32 server. That is, when receiving AT+USERMCUSLEEP=0 command from Enter the command AT+RST with a new line (CR LF) to the “AT command/response” line. Cancel to send in Wi-Fi normal sending mode.
