Closed BNNorman closed 3 years ago

BNNorman commented 3 years ago

Please take a look at my changes. I have added a new test: test_downlink.py I have added logfile names to test.py and test_downlink.py. I have updated README.md, a bit. I have modified dragino.py to enable the capture of data down messages.

regards Brian Norman

Thanks for working on this. I'll have a look later in the week when I get some time.

It looks good and behaves on my device. I've made a couple of suggestions for changes to be made. If you're happy with them I'll do the merge.

  1. Install the required packages sudo apt install device-tree-compiler git python3-crypto python3-nmea2 python3-rpi.gpio python3-serial python3-spidev python3-configobj 5. Download the git repo git clone https://github.com/computenodes/LoRaWAN.git + 1. make a copy of dragingo.ini.default 'cp dragino.ini.default dragino.ini' ⬇️ Suggested change
  2. Enable additional CS lines (See section below for explanation) 1. Change into the overlay directory cd dragino/overlay 2. Compile the overlay dtc -@ -I dts -O dtb -o spi-gpio-cs.dtbo spi-gpio-cs-overlay.dts. This might generate a couple of warnings, but seems to work ok 3. Copy the output file to the required folder sudo cp spi-gpio-cs.dtbo /boot/overlays/ 4. Enable the overlay at next reboot echo "dtoverlay=spi-gpio-cs" | sudo tee -a /boot/config.txt 5. Reboot the Pi sudo reboot 6. Check that the new cs lines are enabled ls /dev/spidev0.* should output /dev/spidev0.0 /dev/spidev0.1 /dev/spidev0.2. In which case the required SPI CS line now exists -7. Create a new device in The Things Network console and copy the details into the config file +7.
