Using Ruby to build a dashboard on a Raspberry Pi is great for:

The Raspberry Pi’s own web browser can also connect to the dashboard app (this is what I did to get the photo below). It can be used to build a dashboard on the Raspberry Pi using its Smashing dashboard library (Ruby libraries are also called gems).Ī web browser can connect to the Ruby app running on the Raspberry Pi to display the data. Ruby is an easy to use programming language that runs on Raspberry Pi. If you need help collecting some data first, check out my guide here: /collect-data-with-raspberry-pi/ Ruby and Smashing dashboard The tools here will help you build a dashboard server that you can then visit from a browser running on your Raspberry Pi or from another device on the same network. Nearly all of the example dashboards in this guide use a web browser (Chromium, Firefox etc.) to actually view the dashboard. In the interim, please feel free to check out other Bluetooth ® developer resources.Raspberry Pi powers all these dashboards (tested using my R Pi 4) The full updated step-by-step guide, How to Deploy BlueZ on Raspberry Pi3 and Use It will be available soon. Then, BlueZ v5.50 will be deployed on your R Pi3 board successfully After completing the two steps above for ell and BlueZ v5.50 source code, return to the Bluetooth step-by-step guide, Section 2.5, Compile and Install BlueZ, and follow this guide to finish setupĥ. Issue the commands below to fetch the BlueZ v5.50 source code cd ~Ĥ. Issue the commands below – these commands will help you to install ell on your R Pi3 board cd ~ģ. Follow the guide till completing “Section 2.3, Install json-c for BlueZ v5.49”Ģ. To clean this error and build a clean development environment to deploy BlueZ v5.50, use the following patch:ġ. The reason for this error is that BlueZ v5.50 uses a new library, Embedded Linux Library( ell). The error is as below, require a library, ell, and the version should be higher than v0.3.Ĭonfigure: error: ell library >= 0.3 is required When deploying BlueZ v5.50 on Raspberry Pi3 using the guide above, an error may pop-up in the command for “Section 2.5, Compile and Install BlueZ”

Some notable new features include a ‘node-reset’ command to meshctl, a new btmon-logger daemon to perform logging on unattended systems, and a new general discoverable property in the advertising D-Bus API.” “This release contains several fixes to GATT and Mesh support. Since the release of this step-by-step guide, the latest version of BlueZ v5.50 has become available and includes updates for Bluetooth mesh. This step-by-step guide shows you how to deploy BlueZ v5.49 on a Raspberry Pi3 board and have it function as a Bluetooth mesh provisioner. Recently, we released a Bluetooth ® step-by-step guide on How to Deploy BlueZ v5.49 on Raspberry Pi3 and Use It, Part 1.
