Configuration
The device is shipped with default configuration parameters. Local changes can be made via the config port using the USB Config Adapter and the Lobaro Config Tool.
For step-by-step instructions, see the Configuration Methods guides:
- 🔌 Local Config via USB — connect directly to the device
- 📡 Remote Config via CoAP — over NB-IoT / LTE-M via Lobaro Platform
- 📻 Remote Config via LoRaWAN — via LoRaWAN downlink
- 🔗 Remote Config via MQTT — for 3rd party MQTT backends
Custom factory configuration is available on request — devices can be pre-configured at production for your specific deployment. Contact sales@lobaro.de when ordering.
Firmware Updates
The latest firmware can be found here:

For further information on how to update the device, refer to: Firmware Update.
A remote firmware update over LoRaWAN is currently not possible.
Default Values are the firmware defaults. Depending on the application the device may be delivered with different settings, see chapter below.
Configuration Parameters
This product runs the app-nrf91-origin firmware. To avoid duplication, the parameters are documented centrally with the firmware component and are not repeated here:
- Common firmware parameters — general, wireless M-Bus, LTE and LoRaWAN settings shared by all V4 gateways
- Temperature Add-On parameters — 1-Wire temperature sensor settings
Application specific non-default values
The following parameters are configured in production to align with the application settings:
| Name | Description | Value |
|---|---|---|
| cmodeDurSec | Do not collect C1/T1 mode | 0 |
| listenCron | Cron expression defining when to receive data | H H 10 * * * |
LoRaWAN Uplink Formats
- LoRaWAN Protocol — Status Packet (Port 1) and wM-Bus uplink formats
- 1-Wire / Temperature Add-on LoRaWAN Uplinks
Cellular Uplink (LTE)
Cellular uplink uses CoAP (with the Lobaro IoT Platform) or MQTT for third-party integration. The protocol details are documented centrally with the firmware:
The CoAP implementation details are not publicly disclosed and are intended for use exclusively with the Lobaro IoT Platform. If MQTT is not an option, please contact Lobaro directly.
Wireless M-BUS Parser
A production-ready parser (including split telegram reassembly where applicable, AES-128 decryption for encrypted wM-Bus telegrams, and OMS-compliant data interpretation) is implemented within the Lobaro Platform.
Customers using the Lobaro Platform can utilize this parser directly as part of the platform processing pipeline.
If you are operating a Lobaro Gateway without using the Lobaro Platform, we can provide restricted platform access upon request. This allows you to inspect the parser behavior and use it as a technical reference for your own backend implementation.
Please contact our support team if you require access or further integration details.
