interfaces etc.
(1)Power supply:
Vcc Jump(red circle marked) provides two different modes of power supply. If jump to the right pin,
the module power on through the uart. If jump to the left pin, the module power on through the +5v and
GND pin.
Note：Under normal circumstances using the uart power supply.
(2)Uart:
Uart pins function, uart1 is same to the uart2, according to the figure 1 position:

PC
Figure 2. Wireless-Uart EVK Demo
Under Wireless-Uart EVK normal mode, uart1 connected as shown in figure 2. Power supply through
uart1.
2. Install USB-UART converter driver (FTDI D2xx driver). Customer can download from below
website.

4. Then open serial terminal on the pc side, set the relevant parameters as shown in the following
figure. Baudrate = 115200, Data_bits = 8, Stop Bits = 1, pariyt = none, Flow Control = none. These
values are factory setting.
Note: Under the configuration mode, the uart parameters are same to the factory setting[1].

2.2 Work Mode
2.2.1 TCP Server mode
Once EVK power on, the module start at factory setting mode[1].
1. Configuration the device’s TCP/IP properties.
Obtain an ip address automatically, show as figure 5.
Figure 5. configuration the tcp/ip properties
2. Scan and join the module ap on the device.
Show as figure 6.

2.3 AT configuration commands
If customers press the configuration button when reset the device, the module into the configuration
mode. AT commands can use the uppercase or lowercase letters, but the parameters must be set
as special value, case-sensitive.
AT commands application:
•
help /?:
Input “help” or ”?” <CR>. This command can show all the commands and use information.
•
Tcp-client transmission configure.
Tcp-client work mode’s topology structure:

(1) Uart parameters configuration
If need to change the uart parameters:
Example: BaudRate=9600, DataBits=8, StopBits=1, Parity=none, FlowCtrl=none.
(2) Wifi parameters configuration
If need to change the wifi mode as client:
Example connect h3c ssid: sta/ap=sta, ssid=h3c, channel=1, security=open
(3) Network parameters configuration
If need to change the network parameters:
Example enable the dhcpc, not use the static ip: dhcpd=0, dhcpc=1, ip_addr=0.0.0.0, net_mask=0.0.0.0,
gw_addr=0.0.0.0.
(4) Work module configuration
If need to change the work parameters:
Example change the work_mode as client: tcp/udp=tcp, client/server=client, ip_addr=10.3.1.80, port=3000.
After the configuration, Open serial terminal on the pc side.
