check byte (not contained).
Example:
Data from phone PDA 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 PDA (HEX): FF 00 03 82 01 01 87
Explanation:
The phone PDA send setting command to module, SSID is set to “TEST1”, password is set
to “123456”. The response from module is that the “TEST1” Wi-Fi network exist, the form of
password is correct.
3. 3. 3. 3.8 8 8 8 Simplelink Simplelink Simplelink Simplelink Configuration Configuration Configuration Configuration
Simplelink function main realization module of intelligent network, namely the quick
connect to the AP. Modules work in STA and AP mode, lower Reload pin 0 to 3 seconds, the
module get into the Smartconfig configuration, at this time Ready pin output high and low
level of 0.5 Hz. The handheld device connected to the module to connect to the AP, open
the APP, enter the password, click on "start". Module will automatically restart after
successfully connect to the AP.
Note
Note
Note Note : when using the AT + WSTA AP information query module is connected, password
show SAFE, password is not visible.

1. RFC2217 is an instant change via Ethernet equipment serial port parameters of a
standard protocol, this device supports a similar RFC2217 agreement, not a standard
RFC2217, realize the same function, but the deal easier.
2. Sends a command to the device after this agreement, if do set serial port parameters
meet the requirements, not return anything, if the calibration error or agreement is
wrong, will be as a common packet via a serial port forwarding.
3. TCP Client, TCP Server, UDP Client, and UDP Server, and broadcast the several
patterns are support this function.
4. This command changes take effect immediately, do not need to restart, when effective,
not save, power is lost.
