ESP-12F User Manual AT commands set is divided into: Basic AT commands, WiFi related AT commands, TCP / IP AT 4.3.1.AT Command Description Table 8 Each Command set contains four types of AT commands. Notes: 1. Not all AT Command has four commands. 2. [] = default value, not required or may not appear 3. String values require double quotation marks, for example: AT+CWSAP="ESP756290","21030826",1,4 4. Baudrate = 115200 5. AT Commands has to be capitalized, and end with "/r/n" 4.3.2.
ESP-12F User Manual AT – Test AT startup The type of this command is "executed". It's used to test the setup function of your wireless WiFi module. AT+RST – Restart module Shenzhen Ai-Thinker Technology Co., Ltd http://www.ai-thinker.
ESP-12F User Manual The type of this command is "executed". It’s used to restart the module. AT+GMR – View version info This AT command is used to check the version of AT commands and SDK that you are using, the type of which is "executed". AT+GSLP – Enter deep-sleep mode This command is used to invoke the deep-sleep mode of the module, the type of which is "set". A minor adjustment has to be made before the module enter this deep sleep mode, i.e., connect XPD_DCDC with EXT_RSTB via 0R.
ESP-12F User Manual ATE – AT commands echo This command ATE is an AT trigger command echo. It means that entered commands can be echoed back to the sender when ATE command is used. Two parameters are possible. The command returns "OK" in normal cases and "ERROR" when a parameter other than 0 or 1 was specified. AT+RESTORE – Factory reset This command is used to reset all parameters saved in flash (according to appendix), restore the factory default settings of the module.
