4. AT Commands
This section provides a list of Serial2WiFi commands and their effects. Parameters are
generally ASCII characters, e.g. ATEn with n=1 is the series of ASCII characters ‘A’, ‘T’, ‘E’, and
‘1’. Where some parameters are optional, mandatory parameters are denoted by < > and
optional parameters by [ ]. If a parameter is mandatory, any associated sub-parameters are
also mandatory; sub-parameters of an optional parameter are optional. Parameters must
always be provided in the order given in the command description. When an optional
parameter is not supplied, the comma delimiters must still be included in the command.
Every command starts with the characters “AT”; any other initial characters will cause an
error to be returned.
Command Response: In most cases, valid commands return the characters OK. Invalid inputs
return ERROR: INVALID INPUT.
Some commands may be not supported depending on the version

Responses / Effects
“OK”
IF 1, echo all input.
Ex) ATE0, ATE1
IF 1 responses are ASCII, else numerical
codes.
Ex) ATV0, ATV1
Responses / Effects
UART parameters are immediately reset to
values provided.(9600, 19200, 38400, 57600,
115200, 230400)
Parity is n for no parity, e for even parity and
o for odd parity.
Allowed values are 5, 6, 7 or 8 bits/character,
with 1 or 2 stop bits (1.5 in the case of a 5-bit
character).
Ex) ATB=9600,8,n,1
