| Info |
|---|
With some chargers, the charging current is insufficient to charge the internal battery within five hours completely. As a safety feature, 5 hours is the maximum charging time. The LED (⯊) will turn yellow when the battery is not entirely charged within five hours. Please dis- and reconnect your charger to restart the charging process. Only if this situation occurs more than once in one charging cycle, the battery might have an issue, and you should consult with trained personnel to inspect your device. The LED (⯊) may blink red if charging is done at high ambient temperatures and/or with high currents. As a safety feature, the charging will be interrupted if the battery reaches a temperature of 45 °C, which is indicated by turning the red LED (⯊) off. As soon as the battery is below the temperature limit again, charging is resumed immediately and LED (⯊) will turn red again. This might result in a blinking red LED (⯊). |
2.2 Switch on
Press and hold button (O) or button (X) for 5 seconds to turn the device on. The device will indicate the different phases of the switch-on procedure via LED (▲). During the boot phase, the LED will be red (first high, then normal intensity). Within the subsequent phase, the LED will turn green and may alternate between green and red several times. It's important to remember that the buttons won't work while the device is in this phase. The switch-on procedure is complete once the LED (▲) turns off.

3.2 Cumulocity IoT / Telekom Cloud-of-Things
There is extensive online documentation (external link) that covers all aspects of working with Cumulocity IoT. The following subsections cover the most basic tasks concisely. Please refer to the official user guide (external link) if you have any additional questions.
3.2.1 Register devices
Use the application switcher in the upper left corner of the user interface and navigate to the “Device management” application.
Navigate to “Devices” > “Registration” and click on the button “Register devices”.
Prepare a CSV file that contains the IDs of the devices you want to register and the respective group each device should be assigned with.
| Code Block |
|---|
ID;PATH BV9H-X4ZM-89BH-EZ73;Group A |
Select the “Bulk device registration” optionand upload the prepared file via the “Select file to upload” button.
Your new devices will now be on the list for pending registrations, and their status will be “waiting for connection”.
Switch on your device. Afterwards, you need to manually accept the device via the Cumulocity user interface. The device status will change to “pending acceptance” after the device has connected at least once. Click on the “Accept” button and wait for the device to reconnect. The device registration is now complete.
3.2.2 Potential issues during device registration
The device may fail to store the credentials that are provided by the Cumulocity backend due to the following events taking place during device registration:
The operator initiates a hardware reset through the use of buttons
Disconnection or under-voltage of the power supply
Signs indicating the occurrence of this scenario are as follows:
The device has been registered and accepted via the Cumulocity user interface
The device continues to display the error code CREDENTIALS ERROR
In this case, it becomes necessary to delete the existing device and its credentials in Cumulocity and proceed with the device registration process again. Here is how you can delete an already existing device and its credentials:
“Device Management” > “Devices” > “All devices” > Delete the device
“Device Management” > “Management” > “Device credentials” > Delete the credentials
