Siemens SIMOTICS CONNECT 400 Operating Instructions Manual page 147

Procedure
1. Update the firmware by clicking on the "Update" button, and then proceed as described
below.
To update the firmware, tap on the "Update" button. The Android File Picker opens. Continue
with the update as described in 2. and 3.
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 on again after the connectivity module has restarted and restart the module
replacement wizard and skip steps 1/7, 2/7 and 3/7.
