Table 7 Fast access WI-FI Response for Setting
Example:
Data from phone to module (HEX): FF 00 0F 02 00 54 45 53 54 31 0D 0A 31 32 33 34 35
36 CE
Data from module to phone (HEX): FF 00 03 82 01 01 87
Explanation:
The phone set setting command to module, set the SSID to “TEST1”, password is

Ready Pin Signal Indication
According to the factory setting, the nReady signal have two statuses:
Status 1: High before module finish booting, Low after finishing boot. User devices can
inquiry this signal to check whether the module have finished booting.
Status 2: High before module finish booting, output Heartbeat signal after finishing
boot. The wave pattern of Heartbeat signal is 0.5Hz square wave which duty ratio is 1:1.
User devices ccan query
this signal to judge if modules active “live” or need to reboot.
When module switches to command mode, it will output “0”, which used to distinguish
work mode and command mode.

Similar RFC2217 Auto-adapt Baud Rate Function
RFC2217 is a standard protocol that user ethernet to change the parameter of
ports. This module supports a protocol which is similar to RFC2217, which has same
function as RFC2217 but much simply. Could use AT command to open the auto-adapt
baud rate function:
AT+AABR=on
This command take effect immediately without reboot. Once reboot, the change of this
command is invalided and restore to default value.
