1.1 - How to Use the Aria App
1.1.1 - Checking Operation of Aria App
Required Items
- TWELITE CUE
- MONOSTICK
Insert the Battery
Insert the CR2032 battery with the + side aligned with the + side of the battery holder. If the LED on the TWELITE CUE blinks 3 times, it is normal.
After startup, it transmits every 5 seconds, and the LED blinks once during transmission.

Battery Installation
Also, because the battery holder of TWELITE ARIA is structurally prone to solder joint detachment, please be careful when inserting the battery as follows:
- When removing the coin battery, it is recommended to lightly press the battery holder from above with your finger to reduce force on the solder joints while removing the coin battery.
- When using TWELITE ARIA, it is recommended to use it with a dedicated case that presses the battery holder from above.
Attach Fixing Magnet
By attaching a magnet to the recess at the position shown in the figure, you can stick TWELITE ARIA to a metal surface. Use as needed.

Magnet Installation Location
Insert into Case
Hook the board on the claws on the edge of the case as indicated by the circle marks.

Inserting the Board
Open the Case
Insert a coin into the notch on the case and pry it open.

Where to Insert the Coin

1.2 - Aria App Settings
There are two ways to configure the Aria app.
For details on configurable items, please check Interactive Mode.
Configuration via OTA
OTA stands for Over the Air, meaning wireless communication. OTA configuration is a feature to configure settings without cable connection using Interactive Mode.
Executing OTA requires MONOSTICK.
Configuration using TWELITE R2
It is also possible to connect TWELITE R2/R3 to the 7P interface of TWELITE CUE and configure settings via Interactive Mode.
1.2.1 - OTA Settings for Aria App
OTA settings is a function to perform interactive mode settings via wireless communication.
Procedure for OTA Settings
Perform OTA settings following the steps below.
1. Launch the TWELITE STAGE APP
Install the TWELITE STAGE SDK on your PC, then launch TWELITE_Stage
in the MWSTAGE folder.
2. Write the OTA setting app to MONOSTICK
Open 2: Rewrite App > 1: Select from BIN and select App_ARIA_OTA_...
.
3. Enter setting values in interactive mode
Select 3: Interactive Mode, then edit and save the values.
4. Execute OTA setting
Place the TWELITE ARIA within about 20 cm from MONOSTICK. Turn on the power of the device or bring a magnet close to the magnetic sensor more than 5 times, and confirm that the LED of TWELITE ARIA blinks.
5. Check the output of MONOSTICK
Confirm the output of messages like the following.
If no output is shown, see here.
6. Write back the app to MONOSTICK
Open 2: Rewrite App > 1: Select from BIN and select App_Wings_MONOSTICK_...
.
If OTA Fails
Distance is too far
Messages like the following indicate that the distance is too far.
OTA FAILURE
OTA request TS=20515[ms]
LQI:63 (RF strength, >= 100)
SID:810BA765
TWELITE ARIA:v1.1.1
Protocol Version:0x13
--— LQI is small. Please make TWELITE ARIA closer. —--
In this case, bring MONOSTICK and TWELITE ARIA closer.
Different target
Messages like the following indicate that the firmware of TWELITE ARIA is different or that TWELITE CUE was mistakenly brought close.
OTA FAILURE
OTA request TS=20515[ms]
LQI:180 (RF strength, >= 100)
SID:810BA765
TWELITE ARIA:v1.1.1
Protocol Version:0x11
--— Different protocol version. Please update TWELITE ARIA. —--
In this case, check if you mistakenly brought TWELITE CUE close.
Also, if you rewrote the firmware of TWELITE ARIA, please use TWELITE R2/R3 to write back to App_ARIA
.
1.2.2 - Settings for Aria App using TWELITE R2/R3
Settings can be made by connecting TWELITE R2/R3 to the 7P interface of TWELITE ARIA.

Example connection with TWELITE R2
When using TWELITE R2/R3 to configure, please follow the steps below.
1. Launch the TWELITE STAGE APP
Install the TWELITE STAGE SDK on your PC and launch TWELITE_Stage
in the MWSTAGE folder.
2. Enter setting values in Interactive Mode
Select 3: Interactive Mode, then edit and save values.
1.3 - Interactive Mode (ARIA App)
This section explains features specific to the ARIA app (App_ARIA). For common features, please refer to the TWELITE APPS Manual Top Page.
Interactive mode cannot be used while TWELITE is in sleep mode.
Please start up with the SET
pin connected to GND
. The TWELITE STAGE app and TWELITE R2/R3 automatically perform this operation.

0x00000000 | TWELITE ARIA Mode |
0x04000000 | Open/Close Sensor PAL Mode |
d
: Temperature Coefficient
Specify the coefficient \(d\) of temperature data in the range 0
-60000
.
If 0
, it is disabled. Otherwise, the final temperature is multiplied by \(\frac{d}{1024}\).
D
: Temperature Offset
Specify the temperature data offset \(D\) in the range -2000
to 2000
.
Add \(D\) to the temperature multiplied by 100. The final temperature changes by \(\frac{D}{100}\) °C.
f
: Humidity Coefficient
Specify the coefficient \(f\) of humidity data in the range 0
-60000
.
If 0
, it is disabled. Otherwise, the final humidity is multiplied by \(\frac{f}{1024}\).
F
: Humidity Offset
Specify the humidity data offset \(F\) in the range -2000
to 2000
.
Add \(F\) to the humidity multiplied by 100. The final humidity changes by \(\frac{F}{100}\) %.
Details of Option Bits
Explanation of settings associated with each bit of the option bit value.
00000001
: Enable Transmission to Relay Devices
Enable transmission not only to the parent device but also to relay devices.
You can use relay devices even if this option is not set, but the parent device will eliminate duplicate packets received. At this time, there is no way to know through which relay device the packet was transmitted or if it was not relayed.
If this option is set, the parent device can output a single packet received from multiple devices separately. By analyzing the output connected to the parent device, you can determine near which device the child device was located.
00000040
: Disable OTA Setting Function
Disables the OTA setting function.
00001000
: Enable Encryption Communication
Enables encrypted communication. The other party must also enable encrypted communication.
00010000
: Enable UART Output on Child Device
Enables message output on the child device.
