Description of operation
The Mobile Gateway receives measurement data from SmartKitchen measurement
devices via Bluetooth and LoRa (also repeated) radios and transfers the
measurement data to the SmartKitchen cloud service via mobile network. The
device is meant to be powered from mains current, although it includes an
internal rechargeable battery, which keeps the device operating during the
short power failures. The battery capacity is enough to support about 20 hours
of operation.
The device operation requires that it is located within the coverage area of
the mobile network and within the range of the measurement devices’ data
transfer signals.
The device scans and chooses the best available network operator during the
startup (Mobile Gateway version 2.1 and newer).
The Mobile Gateway does not transfer stored measurement data from the
measurement devices, like other SmartKitchen Gateway devices do. If it is
necessary to transfer the stored measurement data, it can be done with an
Android phone using SmartKitchen Handy application. The device is not designed
to be used in a moving vehicle, because rapid switching of mobile network base
station may cause loss of the network connection.
Internet connection
The Mobile Gateway includes a factory assembled international SIM card, and it
does not have to be connected to WiFi or LAN network. All the network
parameters and settings are preset. The device connects to 4G/LTE network and
internet automatically. The SIM card can be removed or replaced only by an
authorized service.
The SIM card operates in following countries: Bosnia & Herzegovina, Bulgaria,
Croatia, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece,
Hungary, Iceland, Italy, Jersey, Luxembourg, Macedonia, Malta, Monaco,
Netherlands, Norway, Poland, Serbia, Slovakia, Spain, Sweden, Switzerland, and
United Kingdom.
Starting the use
The Mobile Gateway is activated by connecting the device to the mains and switching it on. The version 2.1 searches for the available Mobile networks and chooses the best available one. This takes normally 5-15 minutes depending on the quality of the networks.

Status lights on startup (0-15 min)| Status lights after
the startup
---|---
TURQUOISE VIOLET| Connecting to mobile network| GREEN TURQUOISE| On
alternately =
The device receives the LoRa message and is connected to the server
BLUE RED| Blinks alternately = SIM card is missing or incorrectly
inserted. No mobile network connection.| BLUE RED| Blinks alternately =
SIM card is missing or incorrectly inserted. No mobile network connection.
GREEN| On 500 ms = The device is on and starts operating
On 1000 ms = Self-test completed successfully Constantly on = The device is connected to a mobile network
| RED AND VIOLET| On alternately =
The device receives the LoRa message. No connection to the server.
BLUE| Blinks once per second 10 times = The Bluetooth communication starts
Fast blinking = LoRa module failure Constantly on =
The device is connected via Bluetooth to a mobile phone, for example
| BLUE| Blinks once per second 10 times = The Bluetooth communication starts
Fast blinking = LoRa module failure Constantly on =
The device is connected via Bluetooth to a mobile phone, for example
RED| Blinks 3 times =
Battery voltage low, connect the device to the power supply
Fast blinks = IOT module failure Constantly on = Could not connect to mobile network
| RED| Blinks 3 times =
Battery voltage low, connect the device to the power supply
Fast blinks = IOT module failure
