Maintenance
8.5 Replacing the connectivity module
Procedure
1. Update the firmware by clicking on the "Update" button, and then proceed as described
below.
If you do not want to update the firmware, move on to the next step with the "Next" button.
2. Select the appropriate "*.bin" file. Downloading starts immediately upon selection. During
downloading, a progress bar is displayed. Wait until downloading is complete.
Result:
After the firmware file has been downloaded, a security check is performed and the Bluetooth
connection to the mobile device is reset.
The firmware is then updated. This process takes approximately 1 to 2 minutes. During this
time, the LED on the front of the connectivity module first flashes slowly – and then faster.
The LED goes dark after the firmware has been updated. The connectivity module
automatically restarts after the firmware has been successfully updated.
3. Log in again after the connectivity module has restarted and restart the module replacement
wizard. If you restart the module replacement wizard within five minutes of disconnecting
the Bluetooth connection, module replacement will be resumed at Step 4/7 - Intervals. If the
Bluetooth connection is disconnected for longer than 5 minutes, start the module
replacement and skip steps 1/7, 2/7 and 3/7.
