I am trying to use the SX126x_simple_node.py example and get the following error:

i named the file lora.py

Begin LoRa radio Traceback (most recent call last): File "lora.py", line 17, in if not LoRa.begin() : File "/usr/local/lib/python3.7/dist-packages/LoRaRF/SX126x.py", line 351, in begin self.setSpi(self._bus, self._cs) File "/usr/local/lib/python3.7/dist-packages/LoRaRF/SX126x.py", line 331, in setSpi spi.open(bus, cs) FileNotFoundError: [Errno 2] No such file or directory

It most likely because SPI configuration on your raspberry pi is not correct. In SX126x_simple_node.py SPI bus id is 1 and cs is 0, but bus id 1 is not activated by default on newly installed raspberry pi OS. To activate SPI with bus id 1 on raspberry pi you should edit /boot/config.txt

dtparam=spi=on
dtoverlay=spi1-3cs

After edit the file restart raspberry pi and check if SPI1 is already active using command

ls -l /dev/spidev*

If everything ok, then you will see

/dev/spidev0.0  /dev/spidev0.1  /dev/spidev1.0  /dev/spidev1.1  /dev/spidev1.2

Alternatively you can change your code to use SPI bus id to 0

I found waveshare SX1262_915M_LoRa_HAT is using UART to connect to raspberry pi. So this package will not works. This package only works for connecting SX126x LoRa module using SPI.
