2. SERIAL SETTING
2.1. Serial Tool SecureCRT
Download adddress：http://www.hi-flying.com/index.php?route=download/category&path=1_4
Decompress file and find executable program, then open. Click quick start button to create
connection.
2.2. Configure Serial Parameter
Protocol：Serial
Port: Actual connection port(search by “My PC”->”Device Manager”->”Port(COM and LPT)”. As figure:
)
Notes: Elfin-EW1X the default serial data is as above and user can modify device working parameter
by IOTService.

3. TEST EXAMPLE
Elfin-EW1X use TCP/IP protocol for communication. There is two main parameters one for IP address
and another for port number.
3.1. AP Wireless Networking
Product works in AP mode. All other STA devices connect to product AP. (Product AP does not
support route function, so the STA can not transfer data to each other) The structure is t shown as
below:

IP:10.10.100.102
Step 1：The product default AP SSID is “EW1X_+MAC(last 4 characters)”. It can also search by cli
“show” command. Figure is as below:

Step 2：PC connect to product AP as following picture.
Step 3: Open network connection and connect to Elfin-EW1XAP from Step 1.

Step 4：Forbidden other network card and only remain the current Wi-Fi network card.
Step 5：Open IOTService and find the device. The device will allocate IP address to the STA
connected. STA device IP address will be like 10.10.100.XXX.
3.2. TCP Server Test in AP Mode
Step 1：Open TCP&UDP test tool and generate TCP connection as following steps. Device has
already created a TCP Server (port 8899) for use. TCP&UDP test tool can be downloaded from our
website:
⚫ DestIP：IP address of device which can be found by IOTService.
⚫ Port：Port of TCP Server which can be found by IOTService or set by users own.

Step 2：Click Connection to generate TCP connection
◼ After successful connection, the left turns to be green arrow, yellow if fails.
Step 3：Open serial tool according to following parameters(115200 baud rate as default)
Step 4：Data transmission between TCP and UART is as following.

Step 1：Elfin-EW1X is AP mode by default. If need to work in STA mode connecting to router. There
are following ways:
Method A: Smart Phone connect to Router. Set product nReload pin to low for some time(0.2s < time
< 1.5s) to make it in Smartlink config mode. See appendix Smartlink V8 APP for detail. The following
is the final device find step for IOS and Android. After the Smartlink config successed, the product
works in STA mode and connect to router.

Method Two: PC connect to product AP, and use IOTService tools. The steps are as folloging
⚫ Set to STA mode.

⚫ Do restart operation. And then PC connect to the router and check the product STA connection.
The following show product Wi-Fi connection is OK.
Note：
If change product network mode, it needs restart to be valid.

Method Three: PC connect to product AP, and open product webpage with default IP: 10.10.100.254.
and change the following setting.
3.4. TCP Server Test in STA Mode
Step 1：Open TCP&UDP test tool and generate TCP connection as following steps. Device has
already created a TCP Server(port 8899) for use. TCP&UDP test tool can be downloaded from the
website:
◼ DestIP：Destination IP address.
◼ Port：Destination Port.

◼ After successful connection, the left turns to be green arrow.
Step 3：Open serial tool according to following parameters (115200 baud rate as default)
Step 4：Mutual data transmission between TCP and serial port.
