FIELD APPLICATION ENGINEER
Today, when IoT devices are getting increasingly popular, the number of devices with a SIM card module that works without having to connect to any network is also increasing daily. However, the management of these devices is also becoming important. In particular, data and SIM card management of the devices sent to the cities other than the production city poses serious problems. In cases where the device is subject to any change of SIM card, operator, or number, physical intervention is required and this requires the establishment of serious technical support teams. Our solution for this is CAVLI WIRELESS, which offers eSIM technology and Hubble platform support. Firstly, I’d like to talk about eSIM technology. This can be summarized as a chip embedded in the SIM card, without any hardware. The major advantage of eSIM is the ability to switch between SIM card operators without any hardware modifications. Another advantage is that it is not an external hardware integration, so it is protected against external factors such as oxidation by being affected by the external environment over time.
Together with eSIM technology, we need a platform to manage this technology. Here too, the Cavli Hubble platform comes into play. The Cavli Hubble platform is a software solution used to access features such as operator selection, data planning, separation into different groups, device management, and obtaining information about the current status of devices registered in the system from anywhere with an internet connection.
The Hubble platform offers major advantages over traditional SIM card methods and provides the users with remote grouping and control of devices, as the most important advantage.
CAVLI HUBBLE PLATFORM INTERFACE
The Hubble platform offers a lot of different information on its homepage. Firstly, it offers several different information such as whether the devices are online or not, the signal strength of the devices according to the last information they sent, the distribution of registered devices on operators, the ratio of registered devices to the total devices with different modules such as 2G and 4G. It can also be seen from which country the devices are connected to the latest Hubble platform. To get to this screen, you first need to create a Hubble account. Afterwards, with the help of the steps I will explain in the later stages of the article, you will be able to see the features of your device as a result of the registration process of your device to the Hubble platform with the help of the demo kit obtained from Ozdisan Elektronik. On the homepage of the Cavli platform, you can switch from the menus on the left side to many different tabs. There are 6 different switching options on the menu.
REGISTRATION PROCESS ON THE HUBBLE PLATFORM
For the registration process on the Hubble platform, we first need to have a development kit with eSIM technology. I will explain the topic through the C10AM development kit.
After receiving the device, we connect the USB that says “UART” with the help of the USB cable that comes with it. If you have not previously used the Silicon Labs CP210X series USBUART converter, the driver must be installed. When you see it as a “com port”, your device can benefit from any terminal program.
Firstly, the device needs to be activated with the Hubble Platform account created earlier. For this;
Command can be used. You can get the 3 parameters available here from the Hubble site. Please follow these menu items:
Account id → From your profile information to the upper left side
From the ”View Account” tab
Plan id → From the data tab in the menu on the left side
Group id → From the group tab in the menu on the left side
When the command response is displayed as “Registration Success”, it will now be visible that this device is included in the Hubble account. What needs to be done next is to send a connection command to Hubble each time the module is turned on. After these commands, information about the device can be accessed via the Hubble platform.
