SOFTWARE UPDATE

You will find below a summary of the most important changes to the Stromer firmware. You can have the currently installed firmware version displayed via the menu as follows: MENU/SYSTEM/ABOUT

SUI FW = Firmware of touchscreen
TNT FW = Firmware of communication module

To enable your Stromer to receive a firmware update, switch it on. The Stromer  will need good cell network reception for at least ten minutes. On the SUI FW version 1.4.x and later versions, an indicator notifies you when there is an update ready to install. When the update is ready, activate the "(OFF)" switch. A dialog window appears on the Stromer touchscreen. Here you can choose whether to install the update immediately (Yes) or later (No). You can install the update immediately or postpone installation of the update up to seven times. You will then have to install it.

During the firmware update, the torque sensor values may change. To prevent possible assistance problems, proceed as follows:

Please calibrate the torque sensor after every firmware update. You can calibrate the torque sensor in the SENSOR menu. Make sure you are not applying pressure to the pedals, then press CALIBRATE SENSOR.

  • New indicators to display mobile network reception:
  1. New indicator for GSM signal strength in the riding display
    The more bars are solid, the better the signal strength is
  2. New indicator for GSM signal strength in the riding display
    Circle with a line through it = GSM and GPRS offline
    G = GPRS online
    No G = GPRS offline
    NOTE: The ST2 can only communicate via the mobile network if there is a GPRS connection. So even if the bars indicate maximum signal strength, communication will not be possible if no "G" is displayed.
  3. New indicator for exchanging data packages
    - A flashing arrow pointing down means the ST2 is receiving data.
    - A flashing arrow pointing up means the ST2 is sending data.
  4. New indicator if new firmware is available for your ST2
