How can I find the IP address of my gateway?

If the gateway is configured in DHCP, it might be tricky to find IP address to configure uWiotys.

• On Windows

You can use Angry IP Scanner - the original IP scanner for Windows, Mac and Linux then filter on MAC ADDRESS and / or MAC VENDOR

Open

• On linux

Replace 192.168.1.0 with the network IP.

How to reboot

For iFemtoCell or iStation:

• With Web interface :

  • Administration → Gateway

  • Open

    

    Picture of button

• With Kerlink gateway button:

  • iFemtoCell: Press the reset button located on the side of the gateway.

  • iStation: Press once (JUST only once) the On/Off button.

Warning: an electric reboot can corrupt the update process

How to shutdown

To shutdown, simply unplug the gateway.

How do I know my µWiotys version ?

How do I know µWiotys is fully started?

Open

You will see a green check indication in the Dashboard.

Device update not done

Restart µWiotys, if it doesn’t work, contact us.

I don’t see my device on the interface

Restart µWiotys, if it doesn’t work, contact us.

How do I know my LoRaWAN device is started?

Check in your environment of the device and look at the “Events” menu to see if uplinks data are coming

Modbus registry is not available

If a Modbus registry isn't available, it can mean there is no Lora device configured at this slave address. Check out the Common table at registry 0x0001 to 0x0004 to make sure your slave is correctly configured. If you cannot read the devEui please check your µWiotys configuration file.

For measurement reading, please make sure you are checking the proper Modbus table. You can check the configured Wi6labs reference available in common table registry 0x0005.

Measurement value is 0xFFFF

The measurement Modbus registry will be configured to default value 0xFFFF (or 0x7FFF for signed) until a valid measurement payload is received. The join message will not be displayed in Modbus. When an uplink is received with no valid measurement (config payload, keep alive,...) the timestamp will be updated but not the measurement registry.

Floating point reading example

With Modbus Doctor, we want to read the value of the register 0x302D.
In order to get the right floating point's value (0.04174805), we have to set Modbus Doctor's parameters to the following values:

• Mode : HEXADECIMAL

• Display mode : 32 bits float

• Register : 302D h

• Length : 02 h

• Type : 3 Holding registers

• Check "Swap bytes" box

The value we had in our example, was 0x3D2B0000 in hexadecimal and 0.04174805 in float.

The timestamp value is incorrect

The timestamp contains the date and time of the last uplink message for each slave, so it can take several minutes or hours to refresh depending of the Lora device uplink frequency.

The GW is automatically synchronized with NTP reference. Two NTP servers can be configured. When the GW is started it will automatically gets the time from NTP reference. If no NTP is available, the time of the last shutdown will be used.
