PCB Antenna AT Command Usage Commands are case sensitive and should end with /r/n ESP8266 Module (WRL-13678) Commands may use 1 or more of these types Set = AT+<x>=<...> - Sets the value Inquiry = AT+<x> - See what the value is set at Test = AT+<x>= - See the possible options Execute = AT+<x> - Execute a command Name Power Commands with * have been depreciated in favor of COMMAND CUR and COMMAND DEF. CUR will not write the value to ash, DEF will write the valueto ash and be usedas the default in the future.
