Dependency and pip version problem

rainerfritz commented 7 months ago

Hi!

I try to get the library running on an RPi 3b+ with the 64bit OS headless. The board I am using is the waveshare board with SX1262 via SPI and GPS via serial.

When I compare the version if install directly LoRa RF via pip3 install LoRaRF, the base.py file seems not uptodate as it misses the classes LoraSPI and LoraGpio. So i am going with the version here from github, manual install in an venv.

I do the following: -create virtual env for python python -m venv lora

--activate if not already source lora/bin/activate

--get the LoRa Repo from git - pip is not actual

cd lora
git clone https://github.com/chandrawi/LoRaRF-Python.git

--install dependencies

pip3 install wheel
pip3 install spidev
pip3 install gpiod

--install LoRaRF

cd LoRaRF-Python
python3 setup.py bdist_wheel
pip3 install dist/LoRaRF-1.4.0-py3-none-any.whl

--try to call the receiver example: python3 examples/SX126x/receiver.py

Gives the Error:

Begin LoRa radio
Traceback (most recent call last):
  File "/home/rainer/lora/LoRaRF-Python/examples/SX126x/receiver.py", line 15, in <module>
    if not LoRa.begin() :

    self._chip = _ext.Chip(path)

             ^^^^^^^^^^^^^^^

FileNotFoundError: [Errno 2] No such file or directory

Can it be, that the actual gpiod version 2.1.3 does not work with the code currently?

I changed then in the chip.py the line self._chip = _ext.Chip(path)to self._chip = _ext.Chip("/dev/gpiochip0")which seems to work, but then the chip object complains:

    line = chip.get_line(self.offset)
           ^^^^^^^^^^^^^
AttributeError: 'Chip' object has no attribute 'get_line'. Did you mean: 'get_info'?

Any help to get it running would be awesome. THX, Rainer

Hello Rainer,

I am currently facing the same issue. Have you managed to fix it yet?

Best regards Julian

Edit: I fixed it with the solution described in issue#19

I try to get the waveshare lora hat running with SX1262 and gps. Took me a little bit to find the right documentation. They provide a LoRaRF version, which works out of the box. I had no time so far to have a look where they modified it. If you want to have a look in the meanwhile here is the link. Scroll down to the bottom of the page: waveshare lorarf library

Wow, how could I have not found that earlier? Thank you for that! I was always just relayed to a different product page that had only useless demo code. To be honest though, I am still not able to make it work. I've tried to use the transmitter.py example and at first I got an error with the call to SX126x() and after I fixed that I got an error during the LoRa.begin(). Have you encountered similar issues?

Before you test it with that library, make sure you uninstall from your primary python environment the lorarf package. Thats how I did it:

generate a virtual python environment
activate it and cd into it
copy the whole library into the venv directory
pip install ./sx126x_lorawan_hat_code/python/lora But it worked also without installing it on my side

JulianGa05 commented 6 months ago

That was it, I still had the old installation, thank you so much!! Now it works!
