...

In the detached state, the device is not able to transmit data to the NB-IoT network. First, an attach procedure needs to be triggered, including the following steps:

  1. Select the NB-IoT network in the drop down menu.

  2. Click on the Attach to network button to start the attachment procedure to the selected NB-IoT network

Note: Be aware that the inserted SIM card must correspond to the selected network, otherwise the attach procedure will fail.

...

In the attached state the device is now able to transmit data via the NB-IoT network.

  1. Button to start a transmission to the cloud of the entered text ( 2 in figure 6) as well as the current cell information.

  2. Text field to enter example text to be transmitted when button (1 in figure 6) is pressed.

  3. Button to start a cell information update.

  4. List which shows all received cell information of the last successful cell information update (see Displayed parameters in figure 8 below).

  5. Button to open IoT Manager website to view all successfully transmitted values as described in figure 7.
