Introduction[edit | edit source]
This Technical Note (TN for short) illustrates the same application described here with some notable differences:
- The edge device is Orca SBC instead of SBCSPG gateway.
- Fledge and Fledge GUI were not installed by using
apt. They were built on the target instead, even though the Linux distribution is still Debian 11. This approach may be more suited to address different situations. For instance, think about the case in which you have to develop new functionalities or test custom north/south plugins. At large, this set-up allows to develop the code on a PC host running the same distribution, and to migrate to the target later on when it is already tested and debugged thoroughly. - As the target platform features an HDMI port, Fledge GUI can be displayed locally, too. This solution can be convenient for building products that require a local display without having to implement a new graphics application.
Building and running Fledge and Fledge GUI[edit | edit source]
For convenience, sshd was set up in order to access the target remotely over SSH connections. This step is not strictly necessary, but it is recommended because it allows to work more effectively as shown in the rest of the article.
Furtehrmore, armbian user was added to the sudoers file as Fledge may require root privileges to execute some operations. As we are working in a development environment, this can be tolerated.
Fledge and Fledge GUI were built starting from the develop of their respective GitHub repositories.
armbian@sbcorca-00a5:~/devel/fledge$ git clone https://github.com/fledge-iot/fledge.git ... armbian@sbcorca-00a5:~/devel/fledge$ cd fledge armbian@sbcorca-00a5:~/devel/fledge/fledge$ make Building Fledge version 2.1.0, DB schema 60 ... uccessfully built cchardet pyjq Installing collected packages: pyjwt, pyjq, ifaddr, cchardet, zeroconf, urllib3, multidict, idna, frozenlist, charset-normalizer, certifi, attrs, async-timeout, yarl, requests, aiosignal, requests-toolbelt, aiohttp, aiohttp_cors Successfully installed aiohttp-3.8.1 aiohttp_cors-0.7.0 aiosignal-1.3.1 async-timeout-4.0.2 attrs-23.1.0 cchardet-2.1.7 certifi-2022.12.7 charset-normalizer-2.1.1 frozenlist-1.3.3 idna-3.4 ifaddr-0.2.0 multidict-6.0.4 pyjq-2.5.1 pyjwt-1.6.4 requests-2.28.2 requests-toolbelt-0.9.1 urllib3-1.26.15 yarl-1.7.2 zeroconf-0.27.0 [notice] A new release of pip is available: 23.0.1 -> 23.1 [notice] To update, run: python3 -m pip install --upgrade pip armbian@sbcorca-00a5:~/devel/fledge/fledge$ export FLEDGE_ROOT=/home/armbian/devel/fledge/fledge armbian@sbcorca-00a5:~/devel/fledge/fledge$ $FLEDGE_ROOT/scripts/fledge stop ; $FLEDGE_ROOT/scripts/fledge start It looks like Fledge is not running. Starting Fledge v2.1.0....... Fledge started.
armbian@sbcorca-00a5:~/devel/fledge$ cd fledge-gui armbian@sbcorca-00a5:~/devel/fledge/fledge-gui$ yarn install && yarn start --host 0.0.0.0 --port 4200 yarn install v1.22.19 [1/4] Resolving packages... armbian@sbcorca-00a5:~/devel/fledge$ git clone https://github.com/fledge-iot/fledge-gui.git ... Build at: 2023-04-18T16:04:36.723Z - Hash: b7cd6cc33931ce39 - Time: 98000ms ** Angular Live Development Server is listening on 0.0.0.0:4200, open your browser on http://localhost:4200/ ** ✔ Compiled successfully.
As stated previously, SSH connections are very convenient when it comes to interact with the target platform during the software development. The following screenshot shows, for example, four active connections used to start Fledge, start Fledge GUI, monitor processor load/memory occupation, and monitor system logs.
SSH can also be used to configure VSCode for remote development as illustrated here. This set-up is very useful to explore/edit source code remotely, for instance.
On the ThingsBoard IoT platform side, we can verify that data is uploaded from the target as expected:
Visualize Fledge GUI on a local display[edit | edit source]
To visualize the GUI on a local display, we run a web browser configured to operate in kiosk mode.
armbian@sbcorca-00a5:~$ sudo apt update Hit:1 http://deb.debian.org/debian bullseye InRelease ... armbian@sbcorca-00a5:~$ sudo apt-get install chromium Reading package lists... Done ... files /lib/systemd/system/weston.service /lib/systemd/system/browser.service armbian@sbcorca-00a5:~$ sudo systemctl enable weston Created symlink /etc/systemd/system/graphical.target.wants/weston.service → /lib/systemd/system/weston.service. armbian@sbcorca-00a5:~$ sudo systemctl start weston Job for weston.service failed because of unavailable resources or another system error. See "systemctl status weston.service" and "journalctl -xe" for details.
