Configuring the device
Register the device
The imei can be found on the top cover of the device, please register the device in your iotcreators project before attempting to connect the device to the network. The device must be registered through the API, since the portal does not support LWM2M registration yet.
Register the device
After registering the device, create a subscription in order for the data to be delivered to your application endpoint.
Create subscription for uplinks and downlinks
Then, create subscriptions for these three events: update, registration and deregistration.
Update, registration and deregistration subscription creation
Opening the device
Unscrew the screw that hold the cover in place. This is the top view of the board:
Inserting the sim card
Remove the cover, you will see the device inside with the battery holders and the sim tray.
Connecting the device to a computer
You can then configure the device by attaching a mini-usb cable to the device, start teraterm, with baudrate set to 115200 bps.
Download teraterm
Please set the tera term terminal as shown here for the device:
First startup
The device will automatically boot up though usb connection.
Enter configuration mode
To read the current settings, just input "settings".
Just input

Setting network parameters
You will need to configure the usual iotcreators parameters in order to attach the device to the iotcreators, APN, server address and port, LWM2M settings (key, identity).
The device must be configured with pre-shared keys (PSK).
Settings can be set with this syntax:
settings set [module] [ro] value
You can configure the device to connect to the the network and to the lwm2m server with a simple script, that you can copy paste from here:
sendln 'settings set modem apn <apn_here>'
mpause 500
sendln 'settings set hub remote_ip 172.27.130.105'
mpause 500
sendln 'settings set hub remote_port 5684'
mpause 500
sendln 'settings set hub lifetime 80'
mpause 500
sendln 'settings set sec mode 10'
mpause 500
sendln 'settings set sec psk_id <your_imei_here>'
mpause 500
sendln 'settings set sec psk <your_psk_key_in_hex_string_format_here>'
mpause 500
sendln 'settings set hub protocol udp'
mpause 500
sendln 'settings set hub type lwm2m'
mpause 500
sendln 'settings set lwmm bs_ena 0'
mpause 500
sendln 'settings set lwmm ep "<your_imei_here>"'
mpause 500
sendln 'settings set core transport modem'
mpause 500
sendln 'reboot'
mpause 500
If is suggested to manually configure the plnm id of your desired network if you are sure the device will stay stationary, to do so just paste these lines on top of the previous script as so:
sendln 'settings set modem op <plnm_id>'
mpause 500
Just save it with .ttl extension and load it in Tera Term in Menu Control ---> Macro.
See below to configure the right APN:
Check network connection info
Working mode
Device registration
If the connection parameters have been correctly input, the device will initiate the connection and send a registration message, that you will receive on your application endpoint.

Reading data from the sensor
The device will update the connection at predefined times. Every time the device updates, it is ready to receive a read request for 10 seconds. This is because it works in "U" binding.
The device features a humidity and temperature onboard. They can be read as for the official LWM2M registry suggests.
- Temperature: 3303/0/5700
- Humidity: 3304/0/5700
This is an example of what is returned by the sensor when reading the temperature (temperature returned in degrees celsius).

Observing
You can also observe a resource (e.g its value will be automatically sent at every device update without the need of an explicit read), see below for the details.
