Firmware Upgrade is the service tool by efleetcon GmbH for ETC2 devices. The app transfers firmware wirelessly over Bluetooth Low Energy – no laptop, no cable, no extra software.

The process follows five fixed steps and guides you through the update:

• File – the matching firmware file ships with the app and is already selected. • Device – the app scans for ETC2 devices in range and shows their name and UUID. • Status – the connection is established and stays visible while you work. • Answer – the device is queried before the update starts. • Update – enable bootloader, initialise DFU, upload firmware, complete.
