Commissioning
6.3 Commissioning with iOS
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 display on the front of the connectivity module flashes, initially slowly and then
faster. After the firmware update, the LED goes out. After the successful firmware update, the
connectivity module restarts.
3. Log on again after the connectivity module has restarted and restart the commissioning
wizard. If you restart the commissioning wizard within five minutes of disconnecting the
Bluetooth connection, commissioning will be resumed at Step 4/7 - Intervals. If the Bluetooth
connection is disconnected for longer than 5 minutes, start commissioning at Step 1/7 -
Device Credentials.
