Unlike the standard Raspberry Pi, the balenaFin comes with mPCIe and micro-SIM slots, making assembling the hardware components and incorporating cellular connectivity super easy. We're looking forward to creating many new projects using cellular data and testing different GSM modules as well. For that, keep an eye on the blog for new posts!

After balenaEtcher is done flashing the device, you can turn it ON and open the dashboard and within minutes it will pop up on the screen. You can check the balenaFin getting started guide for more information here.

The entire code for this project can be downloaded from https://github.com/balena-io-playground/gps-tracker. For more information on how to push code from the git repository to your device, please refer to the getting started guide.

Hologram is a great tool if you want to add GSM connectivity to your application. The company has created a platform where you can easily manage multiple SIM cards that can be deployed to 196 different countries around the globe, all using an uncomplicated billing system. For more information about the service, check out hologram.io.

Until recently, you could only SSH into development devices, via port 22222. The main issue there was that the SSH server on these devices have no authentication, leaving it open for anyone to access it. Starting on the OS version 2.26.0, you will also be able to connect securely to production devices via SSH. This is a huge improvement as engineers and fleet managers will be able to get inside the devices without having to rely on balenaCloud. This feature will be extremely important for this project, as we will disable balenaCloud VPN in order to reduce the daily bandwidth usage for each device.

The Hologram service provides a tool called spaceBridge which allow users to securely ssh into devices through the Hologram network. Since balenaOS devices run a socket activated SSH daemon on port 22222, and we have added our custom SSH key, we can simply set up spaceBridge following the hologram spaceBridge guide.

Now if we set up spaceBridge to create a link between our device’s port 22222 and our computer's port 3000, we should have a secure SSH tunnel into the host of our balenaOS device even with the balenaCloud VPN disabled!

With that in mind, we have released an updated 2.27.0 OS that fixes this issue by allowing users to predefine custom udev rules in the hostOS, improving the reliability of our systems and fixing an annoyance for fleet owners. In our current project, we will predefine a device name for our modem so that every time we boot the device, it will have the exact same name.
