One v1 – SODAQ Payload

One v1 – Cayenne LPP

ONE v2

One v2 – SODAQ payload and Cayenne LPP

ONE v3

This is the end of life version of the SodaqOne tracker made for the ONE v3.

Universal Tracker – SODAQ payload and Cayenne LPP
This is the new Universal Tracker made for the ONE v3, AFF and SFF boards.


Unzip the packet.
Open the .ino file with the Arduino IDE.
Select the correct Board and Port and upload the sketch to your board.


If you don’t see a port the Sodaq One is maybe in sleep.
1x reset the board will normal reset, tracker code has 30 seconds before it disconnects the usb.
2x reset in a second will manually put the Sodaq One into bootloader mode.

Configure your board

After compiling the source code and uploading it to the board you will be able to configure the board through a menu.

Open the Arduino Serial Monitor to see the bootup menu.
Make sure New Line and Carriage Return are enabled.

The bootup menu will close itself after 30 seconds.
When you don't see the menu send an (empty) command.
After every command the menu will reload with the latest parameters and the timer will reset.
The Serial Monitor needs te be closed in most cases before uploading a new sketch.
A power toggle and pressing the reset button require to close and re-open the Serial Monitor.

The LoRa HWEUI is shown, by default also in the dev= field. Write this Hardware EUI down, you will need it later.


There is an issue with RN2903 that the current tracker payload does not fit in SF10.
In the menu settings we have to prevent to use SF10.

  • Turn off ADR: adr=0
  • Set Spreadingsfactor 7, 8 or 9: sf=9

A Thingsboard tutorial will come soon.


Ubidots made a tutorial how to connect our SODAQ ONE sending over The Things Network and show it on the Ubidots dashboard.

We will send the following values in the downlink:
– Fix interval 23 minutes
– No Alternative fix interval
– GPS timeout of 120 seconds

Al values need to converted to hex, adjusted to correct lenght and converted to little endian.

Fix interval of 23 minutes
23 to hex = 17
Lenght correction: 00 17
Change to little endian: 17 00

No alternative fix interval:
00 00
00 00 00 00
00 00 00 00

120 to hex = 78
Lenght correction: 00 78
Change to little endian: 78 00

Combine the values:

1700 0000 00000000 00000000 7800

If the queue the hex in your LoRaWAN network, the next time a message from the device is send it will sent the first queued message.
