Application ​
The RH2 comes pre loaded with fully featured application for RTK data collection as an RTK rover, or as a base station for other rovers, tracking location at 1Hz, 2Hz or 10Hz.
When tracking, by default, data will be sent to the Lightbug Cloud. You can access the data sent to the cloud by API. The Cloud can also be configured to store data, forward it to other services, or publicly share snapshots of the data.
đź§Ş Alpha
The cloud connection, or link can also be configured to point to a private UDP server, that would receive messages directly from the device, via the device communication protocol.
If you would like to use this feature, please contact us for more information.
Home ​
The home screen shows basic device status, and basic device control.
The status bar at the top shows:
- SIM status
- GSM status and signal strength
- Battery level
- Charge state
Disarmed ​
A device would normally start in a disarmed state.
In this state the device is not attempting to get a GNSS fix or report its location, or connect to GSM.

The center button can be used to arm the device (See armed below).
Or the menu button can be used to access the menu below.
The actions selection can be used by custom ESP32 applications to provide quick access to custom actions. Unless something is listening for the button press, it will do nothing.
Armed ​
When armed the device will find it location using GNSS, and report it to the Lightbug Cloud, then streaming RTK corrections if available for the device.
Information above the status of this process will be shown on the screen.

GNSS Status ​
The GNSS status will be one of the following:
GNSS status | Meaning |
---|---|
Acquiring GPS | The device is searching for enough satellites to get a fix. |
Accuracy x.x m | The device has a GNSS fix, and is reporting its accuracy. |
Correction State ​
The correction state will be one of the following:
Correction state | Meaning |
---|---|
Connecting to server... | The device is attempting to connect to the Lightbug Cloud to get correction data. |
Awaiting correction data | The device is connected to the Lightbug Cloud, but has not yet received any correction data. |
Corrections active | The device is receiving correction data, and applying it to its GNSS fix. |
Menu ​
The menu allows selection of:
- Base station mode (allowing the device to work as an RTK base station)
- 1Hz RTK tracking
- 2Hz RTK tracking
- 5Hz RTK tracking
- Displays the Device ID
