Firmware Update

Via W-BACnet app

(for devices on firmware version 3.1.0 and above)

Our app is available for both iOS and Android devices. Once downloaded and launched, a scanning screen will appear, instructing the user to "Set your device to app mode".

To connect the app to device, the module needs to be have bluetooth enabled:

It will then be possible to connect the app to the module for 3 minutes.

If there is a firmware update available for the connected device, the application will provide an onscreen option to start the update. The app will display the progress in real time.

If an update was performed on a gateway device the update will automatically propagate to all nodes in the network. Typically this propagation takes 30 minutes to 2 hours, but can take longer depending on the size of the network.

Switching update channel

If updating to beta firmware, you need to switch the update channel. When the app is starting, tap the LumenRadio logo 8 times and select Beta mode.

Via nRF Connect App

The firmware of the W-BACnet module can be updated using Nordic Semiconductor's nRF Connect app, available for both Mobile and Desktop devices.

To update the device, the module needs to be put in bootloader/DFU mode. This can be accomplished in one of two ways:

  • Set BOOTLOADER_ENABLED to 1 using the SPI or UART interface.
  • Drive the BOOTLOADER pin low while booting the module with the nRESET pin. Once the module has booted into DFU mode, the BOOTLOADER pin doesn't need to be driven any longer.

Once in DFU mode, the module can be found in nRF Connect's list of Bluetooth devices. Connect to the device and use the zip-file found here to update to the latest version of our firmware.

The module will boot in application mode again if no BLE activity has occurred in 2 minutes. Performing a reset via the nRESET-pin will also immediately boot the module in application mode again.
