LoRa US Rx

This sample demonstrates receiving packets over the LoRaWAN protocol. (For US version.)

To make Raspberry Pi communicate with the LoRa module, you should swap the serial ports of the Raspbian OS. Set "/dev/ttyAMA0" to 'serial0'. Also, disable the console on 'serial0'. For a how-to, visit swapping the serial ports topic.

To run the sample:

1. Download the sample code from https://github.com/Turta-io/LoRaHAT/blob/master/Samples/Python/lora_us_rx.py

2. Copy the sample code to a folder on the Raspberry Pi.

3. Open terminal, and then go to the folder you copied the sample.

4. Run the sample with the following command:

python3 lora_us_rx.py

Sample Code

lora_us_rx.py

#!/usr/bin/env python3

#This sample demonstrates receiving packets over the LoRaWAN protocol. (For US version.)
#Install LoRa HAT library with "pip3 install turta-lorahat"

#Raspberry Pi Configuration
# - You should enable SPI and I2C from the Raspberry Pi's configuration.
# To do so, type 'sudo raspi-config' to the terminal, then go to 'Interfacing Options' and enable both SPI and I2C.
# - You should swap the serial ports of the Raspberry Pi.
# Set "/dev/ttyAMA0" to 'serial0'. Also, disable the console on 'serial0'.
# For a how-to, visit our documentation at https://docs.turta.io/how-tos/raspberry-pi/raspbian/swapping-the-serial-ports

from time import sleep
from turta_lorahat import Turta_LoRa

#Initialize
lora = Turta_LoRa.RN2XX3(region = Turta_LoRa.REGIONS.US_RN2903, auto_config = Turta_LoRa.CONFIG_MODES.LORA_RX)
print("Radio is set to receive.")

try:
    while True:
        #Check for serial port buffer
        buffer = lora.check_data()

        #If data is received, print it
        if buffer is not None:
            print(buffer)

#Exit on CTRL+C
except KeyboardInterrupt:
    print('Bye.')

Result

When you run the sample, it prints the incoming data, if any, from the default radio frequency. When incoming data is captured, the example output should be like this:

LoRa board temp: 28.0C

To stop the Python script, just press CTRL + C.
