Preparation:

1. Ensure you have access to a PC and a standard comms board.
2. For safety, only update one Gen-2 QTFM sensor at a time.
3. Firmware updates cannot be performed over Bluetooth.

Step-by-Step Instructions:

1. Install the Updater:

1. • Download the Qtfm2FirmwareUpdater installer from this link.
   • Follow the installation process to install the updater on your PC.

2. Connect the Sensor:

1. • Connect the Gen-2 QTFM sensor to your PC using the standard comms board.
   • Determine the comport of the sensor:

1. • • Use the device manager on your PC to identify the sensor’s comport.

3. Prepare the Sensor for Update:

1. • Ensure the sensor is not in automatic start-up mode.
   • If in automatic start-up mode:

1. • 1. Connect to the sensor using the QTFM interface.
     2. Use the Ascii command ‘O’ (Decimal:79) to toggle automatic start-up off.
     3. Reboot the sensor. After rebooting, the ECU should slowly blink red, indicating the sensor is ready for the firmware update.

1. • Fully exit the QTFM interface:

1. • • Press the ‘End’ key on your keyboard to release the comport.
     • Close the QTFM interface software.

   • Enter the confirmed comport and press ‘Enter’.
   • The firmware update will start and should not take more than 1 minute.

1. • • Important: Do not power down the sensor or interrupt the update process, as this can corrupt the ECU.
