LoRaWAN™ Configuration
Activation of an end-device can be achieved in two ways, either via Over-The-Air
Activation (OTAA) when an end-device is deployed or reset, or via Activation By
Personalization (ABP) in which the two steps of end-device personalization and activation
are done as one step.
Over-the-Air Activation
For over-the-air activation, end-devices must follow a join procedure prior to
participating in data exchanges with the network server. An end-device has to go
through a new join procedure every time it has lost the session context information. The
join procedure requires the end-device to be personalized with the following information
before its starts the join procedure: a globally unique end-device identifier (DevEUI), the
application identifier (AppEUI), and an AES-128 key (AppKey).
Activation by Personalization
Under certain circumstances, end-devices can be activated by personalization.
Activation by personalization directly ties an end-device to a specific network by-passing
the join request join accept procedure.
Activating an end-device by personalization means that the DevAddr and the two
session keys NwkSKey and AppSKey are directly stored into the end-device instead of
the DevEUI, AppEUI and AppKey. The end-device is equipped with the required
information for participating in a specific LoRa network when started. Each device should
have a unique set of NwkSKey and AppSKey. Compromising the keys of one device
shouldn‘t compromise the security of the communications of other devices.
Operation Mode
Bi-directional end-devices (Class A): End-devices of Class A allow for bi-directional
communications whereby each end-device's uplink transmission is followed by two
short downlink receive windows. The transmission slot scheduled by the end-device
is based on its own communication needs with a small variation based on a random
time basis (ALOHA-type of protocol). This Class A operation is the lowest power
end-device system for applications that only require downlink
communication from the server shortly after the end-device has sent an uplink

Response:
ok ﹣parameter is valid
invalid_param ﹣parameter is not valid
transmission. Downlink communications from the server at any other time will have
to wait until the next scheduled uplink.
Bi-directional end-devices with maximal receive slots (Class C): End-devices of
Class C have nearly continuously open receive windows, only closed when
transmitting.
MOST-Link Configuration
Please refer to below AT Command List for the detail setting.
AAT1 － Command for parameters setting up and send /receive data.
AAT3 － Command for functions setting up under MOST-Link.
Under this protocol, the default mode is Disable (P0=0), which is the payload data
transmission in transparent. It only supports command A0, A1 for AES128 encryption
function.
Use AT command [AAT3 P0=1] to Enable MOST-Link mode.

In Wake up mode, LM-130H1 stays
awake and send wake up code (i.e.
Normal mode plus with preamble byte)
while transmitting data.
2.
In Power-saving mode, LM-130H1 sleeps
all the time. Send [AAT1 WK] or any
command would get “ACK” as a wake up
code. After getting “ACK” within 0.5
second, send [AAT3 MD=1] to change it to

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.
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 transmitter must not be co-located or operating in conjunction with any other
antenna or transmitter.
FOR MOBILE DEVICE USAGE (>20cm/low power)
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 device is intended only for OEM integrators under the following conditions:
1) The antenna must be installed such that 20 cm is maintained between the antenna
and users, and
2) 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.
End Product Labeling
This transmitter module is authorized only for use in device where the antenna may be
installed such that 20 cm may be maintained between the antenna and users. The
final end product must be labeled in a visible area with the following: “Contains FCC
ID:RID-LM110H1”. The grantee's FCC ID can be used only when all FCC compliance
requirements are met.
Manual Information To the End User
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.
