Hello, I try to use your block LoRa receiver but i have the following error: File "/home/mcharfi/top_block.py", line 76, in __init__ self.lora_lora_receiver_0 = lora.lora_receiver(1e6, 868e6, 100e3, 7, 1000000, 0.01) File "/usr/lib/python2.7/dist-packages/lora/lora_receiver.py", line 49, in __init__ self.c_decoder = lora.decoder(out_samp_rate, sf) AttributeError: 'module' object has no attribute 'decoder' OOOOOOOOOOO.. During the installation i had some warning after use the command line: cmake -DCMAKE_INSTALL_PREFIX=/usr result: install1.txt

and after the command make result:install2.txt

after sudo make install: install3.txt.

I tried the other solution discussed in issues #13 and #17. But without success. Please note that i used Pybombs to install gnuradio companion. Thanks.

Hello there! Are you using Ubuntu? You only need to use the -DCMAKE_INSTALL_PREFIX=/usr flag if you use Arch Linux.

Hello, thanks for your reply. I 'am using Debian, but when i don't set this flag on i can't found the gr-lora module in gnuradio companion, i maybe forgot a step ?

Thanks, I don't have this error anymore. I have uninstalled and reinstall all the stuff with pybombs. I used the way describe here that include a recipes of gr-rpp0 for pybombs.
