March 16, 2022

New Functions

• To protect the battery from deep discharge, the Stromer is automatically switched off when the battery level is low.

Connectivity

• The connectivity upgrade for the Stromer ST1 LCI with OMNI Interface C has been unlocked (unlocks the Stromer OMNI App).

• Stromer ST1 LCI without connectivity upgrade can now connect the Stromer BT App.

• Optimizations have been made to the cellular communication.

• The connection process as well as the stability of the connection between OMNI Interface B & C and the Stromer BT App, has been optimized.

• Improvements have been made to the user interface of the software update via Bluetooth for the OMNI Interface B.

• As soon as the Stromer BT App or the smartphone is connected to the OMNI Interface B, the connection status is shown in the information bar.

Battery

• Sometimes the error code "210003" was displayed when the Stromer was switched on because the battery or the power supply was switched on with a delay. New, the error is cleared when the power supply was successfully switched on.

• If an overvoltage is detected, then the recuperation is deactivated.

Charger

• Sometimes, after removing the charger, the error code "210110" was displayed on the Stromer because the power supply was not below a specified threshold during the functionality check after 1 second.

  Now the error is only displayed after 4 seconds.

• If the type of the connected charger cannot be identified, the type of the previously connected charger no longer applies. This prevents the wrong firmware from being downloaded for the charger.

Various optimizations

• Now, the sensor value is monitored and tracked to ensure consistent support.

• It is now detected whether pedaling is taking place during the ride.

• If the PIN code is forgotten/lost on a Stromer with OMNI Interface C, the code can be reset by the specialist dealer after presentation of a vehicle ID or proof of purchase.

SUI FW 4.3.4.6

06.10.2021

Various optimisations

• If a new QR code is requested under Menu/Bike/OMNI to connect a "Stromer OMNI user account", the OMNI interface first checks whether a user account is already connected to this Stromer. If a user account has already been connected, then a note is displayed instead of a QR code.

• A firmware update (V. 01-0103-0105) is available for the Blubrake ABS system. The firmware update is installed automatically, if necessary, after confirmation.

• With this update, optimizations have been made to the performance (for all Stromers older than 2018).

SUI FW 4.3.4.1

11.06.2021

Various optimisations

• New when driving in sport mode (ST5 only), the sensor sensitivity is set to 100%. For modes 1,2 & 3, the sensitivity can still be set manually.

• If the PIN code is forgotten/lost on a Stromer with OMNI Interface B, the code can be reset by the specialist dealer upon presentation of a vehicle ID or proof of purchase.

• As soon as a firmware update is available for a component (ABS, battery, lighting, controller and charger), it is displayed by means of a new icon in the status bar. The installation can be started manually via "MENU/SYSTEM".

• The bootloader of the OMNI Interface B & C is updated to version 2019.01 (previously 2016.11) with this update. This fixes an error which meant that an OMNI could no longer be started after an update.

SUI FW 4.3.3.2

11.03.2021

Battery

• New firmware updates are available for the following batteries. The firmware updates if necessary are installed automatically after confirmation.

  - 500Wh V4.56 - 618Wh V1.A.5 - 814Wh V1.57, V3.57 or V5.3 - 983Wh V2.57, V6.3 or V0.A.5

• For batteries with firmware "0.A.5" or "1.A.5", the charging status should now be displayed less erratically.

• For batteries with firmware version "1.57", "2.57", "3.57", "4.56", "5.3" or "6.3", the safety functions have been optimized.

• Driving clearance is withdrawn if it is determined that the battery cannot be deactivated.

Connectivity

• For Stromer ST1 (2019 or newer), which are equipped with an OMNI Interface C, the "SmartLock" function has been enabled.

• The sensitivity range of the SmartLock function has been extended. This allows the range in which the Stromer is unlocked/locked when the paired device is in the vicinity to be set more precisely.

Various optimizations

• The support dynamics of the individual support levels 1 to 3 were distributed more evenly. - Mode 1 is still very economical and corresponds to an ECO mode. - Mode 2 has been optimized (default setting) so that the assistance level is positioned midway between modes 1 & 3. The mode can be adjusted to personal needs via the Stromer OMNI app. - Mode 3 now provides slightly stronger support while maintaining the same sensor sensitivity.

• Optimizations were made to the sensor dynamics for Stromer ST5 & ST3. These adjustments have reduced the amount of force needed until the motor assistance kicks in.

• A QR code can now be displayed in Menu/Bike/OMNI (only with OMNI Interface C). This will make it possible in the future to link the Stromer with the account without having to visit the dealer (an update of the app is necessary, which will be released soon).

• Solves a problem where the charge level freezes while driving after charging.

• When the "Eject" button is pressed, the light and motor support is switched off for 10 seconds. This is a safety measure to protect the electronic components if the battery is disconnected/removed prematurely (before the Stromer is switched off).

  It is still recommended to switch off the Stromer first before removing the battery

  .

Various optimizations

• A new configuration has been added for bikes that are registered in Canada to make them compliant with the law (32Km/h and 500W). The change must be made by the dealer.

  -

  E 210110

  The battery should not be reused and should be returned to the dealer for inspection.

• For the 814Wh & 983Wh battery there is the new firmware version 54.

  If necessary, it will be installed automatically on the battery. This firmware includes new protective mechanisms that permanently deactivate the battery in the event of a short circuit at the 48V output.

  If the battery has been deactivated, the following error messages appear on the OMNI.

  - E 210102 - E 210109

The battery cannot be reused and must be returned to the dealer for inspection.

• As of software version 4.2.1.10 on an OMNI B & C, a protection mode is activated if an overload is detected, which prevents the 48V output from switching on. The following error is displayed on the OMNI. - E 21000E

  The deactivation is cancelled as soon as one of the following batteries is used - Battery with FW 54, 0.9.6 or 1.9.6

  The deactivation can be deactivated after a check by the dealer.

Battery

• Corrects a problem that caused the battery not to be fully charged when OMNI was switched on.

SUI FW 4.2.1.8

21.October 2019

Security

• Error code 0x21000D "Battery current too high".

  Restart the vehicle, if the error persists: Remove the battery and contact your Stromer dealer!

• If a component connected to the 48V output fails, unexpected current and heat may be generated on that component. If this unexpected current is less than the battery cut-off limits, the 48V output of the battery is switched off by the OMNI and the charger is disconnected.

  The error code 0x21000D is also displayed.

Recuperation

• For recuperation via the [-] button, a linear ramp was introduced for speeds from 2 to 10 km/h, so that this type of recuperation behaves similarly to the recuperation via the brake(s).

• The right/rear brake now also has a stronger effect on recuperation, in case that both brakes are applied simultaneously.

Theft protection
