rpilorawan board control script

Aim of this script is to control the rpilorawan board to send messages on the LoraWan network.

The expansion board is for raspberry pi mainboard and allows sending messages over the LoraWan network

You can purchase the board on YADOM.FR.

This python script allows :

reading preprogrammed EUI
joining a network using OTAA or ABP
sending data with or without requesting a response

Usage

reading preprogrammed EUI

python sendlorawan.py --eui

joining an OTAA Lora network providing devEUI (0004A30B001EBA62) appEUI (0000000000000001) and appKey (4E2086153FB762C2E079A1F791792400) and sending frame 0A1B

python sendlorawan.py --otaa 0004A30B001EBA62 0000000000000001 4E2086153FB762C2E079A1F791792400 --send 0A1B

joining an OTAA Lora network providing devEUI (0004A30B001EBA62) appEUI (0000000000000001) and appKey (4E2086153FB762C2E079A1F791792400) and sending frames A4B5 and then FCD45E0C expecting a downlink frame

python sendlorawan.py --otaa 0004A30B001EBA62 0000000000000001 4E2086153FB762C2E079A1F791792400
python sendlorawan.py --send A4B5
python sendlorawan.py --send FCD45E0C --receive

joining an ABP Lora network providing NwkSkey () AppSKey () and devAddr () and sending frame AB50

python sendlorawan.py --abp    --send AB50

Notes Short arguments are supported (ie -p for --port) The serial port path can be specified with option --port, default is /dev/ttyAMA0 The Lora channel can be specified when sending with option --channel, default is 1

Prerequistes

The following steps should be performed in the following order

Disable Raspberry Pi terminal on serial port with raspi-config utility:
```
sudo raspi-config
```
Go to Interfacing Options then choose Serial then NO and OK
Install pyserial
```
sudo apt-get install python-serial
```
Download scripts
- if git is installed then clone the repository :
```
git clone https://github.com/SNOC/rpilorawan.git
```
- otherwise paste script content to a new file:
```
nano sendlorawan.py
```
Plug antenna with its cable and test the communication:
```
python sendlorawan.py --eui
```

Pi3 specific requirements

Edit /boot/config.txt
```
sudo nano /boot/config.txt
```
1. disable if present dtoverlay=pi3-miniuart-bt by adding # character at line begining : #dtoverlay=pi3-miniuart-bt
2. if not present, add :
```
dtoverlay=pi3-disable-bt
enable_uart=1
```
  note: enable_uart=0 might be present at the end of the file, in such case it should be commented or modified to enable_uart=1
then reboot :
```
sudo reboot
```

Serial port to use is the script's default one : /dev/ttyAMA0
