Firmware Update — Local via USB

Update your device locally using the USB Config Adapter and the Lobaro Config Tool.

1. Download the firmware

Get the ~boot.hex file for your device from the product page — e.g. Gateway V4 Series → Firmware. Use the file with the highest available version number, e.g. app-nrf91-origin+0.12.4+hw4~boot.hex for the Gateway V4. The ~boot file bundles the application and secure firmware — everything needed in one file.

Older devices (V3 / Hybrid Gateway)

Older firmware generations use a different naming convention — download both the slot0 and boot.hex files:

DeviceExample file names
wM-Bus Gateway V3app-nrf9160-wmbus+0.28.1+hw3+slot0-boot.hex
Hybrid Modbus DIN-Railapp-hybrid-modbus+0.14.1+dinrail+slot0-boot.hex
  • slot0 is required for local updates
  • boot contains the Secure Boot Firmware

2. Connect the device

Connect the USB Config Adapter to the device's CONFIG port and to your computer via USB. Make sure the device is powered externally.

3. Flash the firmware

In the Lobaro Config Tool, open the FIRMWARE tab, select the downloaded file with Select Hex File, and start the update with Flash Hex File.
