UART Data

Notes

—>

+++

Send “+++” to module RXD PIN.

Note: +++ is three bytes, \r\n(0x0d 0x0a) is not

allowed.

<—

Module TXD output 1 byte “a” to acknowledge

—>

Send “a” to module RXD PIN.

Note: a is one byte and should be input within 3

seconds after modules reponse with “a”

<—

+ok

Enter AT Command Mode, AT Command is allowed

to be used.

—> indicate UART input, <— indicate module response

1.3. Send AT Command in Throughput Mod

Use AT+CMDGD command to set special characters. Add these special prefix characters before AT

Command is applicable to get AT command response in throughput mode. It saves the complexity of frequently

switch between throughput and AT command mode.

For example: If set AT+CMDGD=XM (Default setting), send “XM” + “AT+WMODE=STA” + “\r” in

throughput mode, the module won’t throughput this packet to network. It will direct execute this AT command

and response with “+ok”.

1.3.1. AT Command Syntax Format

AT+Instruction protocol is based on the instruction of ASCII command style, the description of syntax

format as follow.

l Format Description

n < >: Means the parts must be included

n [ ]: Means the optional part
