git clone git@github.com:DGaffney/LoRaWAN.git
This is a LoRaWAN v1.0 implementation in python.
It uses: https://github.com/mayeranalytics/pySX127x
For reference on LoRa see: https://www.lora-alliance.org/portals/0/specs/LoRaWAN%20Specification%201R0.pdf
This fork adds support for the Adafruit LoRA Radio Bonnet with OLED - RFM95W @ 915MHZ.
It also allows you to connect as a client to the Helium Network.
After forking the repo, install the python libs:
pip3 install -r requirements.txt
The keys can be added to a ./.env file:
deveui = 1234ASD432
appeui = 234ASD4321
appkey = 34ASD43210
devaddr = [00,11,22]
nwskey = [11,22,33]
appskey = [22,33,44]
They can also be passed as environment variables:
deveui=1234ASD432 python3 rssi_helium.py
You must create a device on the Helium Console at https://console.helium.com/
After copying the device credentials (the first three in the .env file, above), run otaa_helium.py, which will get the final three credentials for the .env file.
Then you can run tx_helium.py to send messages by specifying the msg and the frame like this:
python3 tx_helium.py --msg "Test" --frame 1
You can run rssi_helium.py which utilizes the OLED screen and buttons.
This will sent a tranmission when it starts and whenever you press the middle button.
The transmission is a confirmed data message so a response will be received if a hotspot is in range.
The message just sends with the same frame to prevent having to track that and since the up link data is not needed.
The script pulls the RSSI, the packet RSSI, and the SNR and displays it on the OLED.
Automatically track frame number. Automatically capture device registration info and put in keys.py.
