#Esp8266 firmware mqtt upgrade#

The Wi-Fi module enters the upgrade mode: GPIO0 is at a low level, then the module is reset and powered on the Wi-Fi module enters the normal working mode: GPIO0 is at a high level, and the module is reset and powered.

Wi-Fi module NRST pin is active low EN enable pin is active high.

Wi-Fi module IO maximum output current is 12mA.

The module supply voltage is 3.3V DC and the current is 500mA or more.

Support Smart Config function (including Android and iOS devices).

Support AT remote upgrade and cloud OTA upgrade.

802.11 i security features: pre-authentication and TSN.

3) Program the NodeMCU The preferred software to program the board is esplorer. built on: 15:59 powered by Lua 5.1.4 on SDK 1.4.0 lua: cannot open a Hurrah Blank firmware works Now to program it to read the DHT22 sensor and report the data with MQTT.

P2P discovery, P2P GO mode / GC mode and P2P power management .modules: node,file,gpio,wifi,net,tmr,uart,mqtt,dht build.Supports CCMP (CBC-MAC, counter mode), TKIP (MIC, RC4), WAPI (SMS4), WEP (RC4), CRC hardware acceleration.Support Station, SoftAP, SoftAP STA mode.Standby power consumption is less than 1.0mW (DTIM3).Wake up, connect and deliver packets within 2 ms.Deep sleep holding current is 10uA, shutdown current is less than 5uA.Peripheral interface HSPI, UART, I2C, I2S, IR Remote Control, PWM, GPIO.Built-in Tensilica L106 ultra-low-power 32-bit microprocessor, the main frequency supports 80MHz and 160MHz, supports RTOS.The ESP-F module provides maximum practicality at the lowest cost, providing unlimited possibilities for Wi-Fi functionality to be embedded in other systems.Users can use this module to add networking capabilities to existing equipment or build stand-alone network controllers. ESP-F module supports standard IEEE802.11 b / g / n / e / i protocol and complete TCP / IP protocol stack.In addition, ESP8266EX can be used as a Wi-Fi adapter through SPI / SDIO interface or I2C / UART port, and can be applied to any microcontroller-based design. The built-in cache memory helps improve system performance and optimizes the storage system. When the ESP8266EX is used independently, it can be started directly from the external flash. ESP8266EX has a complete Wi-Fi network function, which can be used independently or run as a slave on other host MCUs. This chip integrates the industry-leading Tensilica ’s L106 ultra-low-power 32-bit micro MCU in a smaller package, with a 16-bit reduced mode, the main frequency supports 80 MHz and 160 MHz, and supports RTOS. The core processor of the ESP-F module uses the cost-effective chip ESP8266EX.MQTT firmware: refers to the module with MQTT firmware.TT firmware: refers to the module with transparent transmission firmware, this firmware configures the module through the web page, similar to router configuration.AT firmware: refers to the module with AT firmware, this firmware only supports AT instructions to operate the module.
