Pin Assignment
Get Started: Installation
LoRa module is a wireless transceiver which provides an easily controllable CMD interfaces(CLI/UART) that the user would send data quickly with wireless communication protocol. Prepare only one usb cable, users could use any kind of terminal utilities such as TeraTerm, Putty and HyperTerminal to access the CMD interfaces(CLI/UART).
Hardware introduction
As the following figures, you can see a LoRa module mounted on a debugger
board. The red frame indicates the main interfaces on the debugger board,
includes UART, ADC and SPI and so on.
Connect to the computer
Use a micro USB cable to connect to the computer with debug board. When it is
connected, the power LED will turn on. 
Get the comport information
After connected micro USB cable to PC, user can check the COM number in
“Device Manager”, for instances, below figure indicates the COM number is 3.
Execute the terminal utility(PuTTY)
The connection information of LoRa Module is Baud Rate 9600, Data bits 8,
Parity none, Stop bits 1 and Flow control none. Here is an example using PuTTY
to access UART interface.
Click the Open button, then, click the Enter button on the keyboard. When you
see the #CMD:[] which means the connection is successful. 
Sending data
This section provides command examples that used for sending user data.
Example 1: Send a two-byte data 0x1234 senddata 1234
After perform this command, user will see a success state which indicates the
command is correct. Due to the minimum transmission period(default is 60
seconds), user data will not be sent immediately. It can only be sent at the
60, 120, 180… second of system time. As you can see in above figure, the user
data is sent at the 60 second of system time.
Example 2: Perform two senddata commands in a short time. User data are
0x5678 and 0x1234. send data 5678 send data 1234
There will always keep one set of user data during the transmission period. So
the old data 0x5678 will be overwritten by new data 0x1234. In this case, only
the data 0x1234 will be sent. To check the user data on website, please
contact your system provider to create new account.
Commands Usage:
senddata
Description: Sending user data by transmission period(default period is 60
seconds)
Receiving data
The receiving task just after each transmit operation, if a downlink data was received, following message will be displayed:
[Output]
[!] Receive FPort=3, Length=3 [DATA:AA5531]
In this case, the received data is three-byte length and the contents: 0xAA 0x55 0x31.
Federal Communication Commission Interference Statement
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.
FCC Caution: Any changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate this equipment. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.
IMPORTANT NOTE:
Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an
uncontrolled environment. This equipment should be installed and operated with
minimum distance 20cm between the radiator & your body. This transmitter must
not be co-located or operating in conjunction with any other antenna or
transmitter. Country Code selection feature to be disabled for products
marketed to the US/CANADA
Integration instructions for host product manufacturers Applicable FCC
rules to module
FCC Part 15.247
Summarize the specific operational use conditions
The module is must be installed in mobile device.
This device is intended only for OEM integrators under the following conditions:
- The antenna must be installed such that 20 cm is maintained between the antenna and users, and
- The transmitter module may not be co-located with any other transmitter or antenna
As long as 2 conditions above are met, further transmitter test will not be
required. However, the OEM integrator is still responsible for testing their
end-product for any additional compliance requirements required with this
module installed.
IMPORTANT NOTE: In the event that these conditions can not be met (for
example certain laptop configurations or co-location with another
transmitter), then the FCC authorization is no longer considered valid and the
FCC ID can not be used on the final product. In these circumstances, the OEM
integrator will be responsible for re-evaluating the end product (including
the transmitter) and obtaining a separate FCC authorization. The OEM
integrator has to be aware not to provide information to the end user
regarding how to install or remove this RF module in the user’s manual of the
end product which integrates this module. The end user manual shall include
all required regulatory information/warning as show in this manual.

RF exposure considerations
20 cm separation distance and co-located issue shall be met as mentioned in
“Summarize the specific operational use conditions”. Product manufacturer
shall provide below text in end-product manual “This equipment complies with
FCC radiation exposure limits set forth for an uncontrolled environment. This
equipment should be installed and operated with minimum distance 20cm between
the radiator & your body.”

Label and Compliance Information
Product manufacturers need to provide a physical or e-label stating “Contains
FCC ID: 2AQ68-N718US” with finished product
Information on Test Modes and Additional Testing Requirements
Test tool: Tera Term shall be used to set the module to transmit continuously.
Additional Testing, Part 15 Subpart B Disclaimer
The module is only FCC authorized for the specific rule parts listed on the
grant, and that the host product manufacturer is responsible for compliance to
any other FCC rules that apply to the host not covered by the modular
transmitter grant of certification. The final host product still requires Part
15 Subpart B compliance testing with the modular transmitter installed
