tBeamLoRa

This is the sensor node part of a LoRaWAN network to save environmental data to a remote database. The software reads data from several sensors, namely the SPS30 particulate matter sensor, the SEN0170 anemometer, the BME680 temp, press etc module and the LPPYRA03AV pyranometer. A custom shield was also developed: schematics and the KiCad project files are available here.

Setup

0.0 Prerequisites:
  • Install kconfig with sudo apt install kconfig-frontends or whatever for your distro
  • Install kconfiglib with pip install kconfiglib
  • Install PlatformIO Core (see below)
0.1 Install PlatformIO Core
0.1.1 For CLion only:

  • Install PlatformIO Core (needed cuz the plugin is still experimental) with python3 -c "$(curl -fsSL https://raw.githubusercontent.com/platformio/platformio/develop/scripts/get-platformio.py)"

  • In CLion go to Edit->Settings->Plugins->Marketplace and search for "PlatformIO for CLion"

  • Install it (and restart CLion as prompted)

  • Go to Tools->PlatformIO->Home

  • [If CLion complains about paths, run (with sudo)

    ln -s ~/.platformio/penv/bin/platformio /usr/local/bin/platformio

    ln -s ~/.platformio/penv/bin/pio /usr/local/bin/pio

    ln -s ~/.platformio/penv/bin/piodebuggdb /usr/local/bin/piodebuggdb

    This will create links to make CLion believe paths are right. Restart CLion. Type "pio run" in CLion Terminal]

  • In the webpage it opens, click on "Open Project" and select the project's root folder

  • Re-open Clion, click on File->"Close project"

  • In the launcher window, click on open an existing project and select the project's root folder

  • In CLion, open the Terminal click Alt+F12 (or whatever in OS X)

  • Type in "platformio run"

  • Done, follow the steps below.

  • Commands to build, clean, upload etc are under Tools->PlatformIO

  • To build the Doxygen documentation, go to Build->"Build project", the docs is in html folder

1. Edit lmic_project_config.h inside one of .pio library folders and uncomment your frequency
2. Edit hal.h in src/hal/hal.h inside one of .pio library folders and replace in line 25 u1_t with unsigned char
3. Configuration:
  • From a terminal (from the project root) type menuconfig or guiconfig, edit prefs and save
  • Then type genconfig to generate/update the config.h header file
4. Edit this project file main/credentials.h and add the Keys/EUIs
5. Compile and upload. For CLion, see above. Otherwise, use Visual Studio Code with the PlatformIO plugin or the command line
6. Turn on the device and once a GPS lock is acquired, the device will start sending data

Note for CLion users

  • Step 3 can be done in CLion's Terminal

  • If Monitor (serial monitor) under Tools->PlatformIO doesn't work, please open a terminal and type screen /dev/ttyUSB0 115200. Exit with CTRL+a CTRL+d AND type fuser -k /dev/ttyUSB0.

  • You can generate the Doxygen documentation with Build -> Build Project
