Installation documentation

[gtoal]

Can't quite work out how to install into a clean Raspberry Pi from the docs.

So far I've done these:

sudo apt-get install mosquitto
sudo apt-get install mosquitto-dev
sudo apt-get install libmosquitto-dev
sudo apt-get install gnuradio

and unpacked the zip file with all your software in it into ~/src/decode345-master/

When I start the first process I get this:

pi@ebay1:~/src/decode345-master/bin $ python receive345.py
Traceback (most recent call last):
File "receive345.py", line 16, in
import osmosdr
ImportError: No module named osmosdr

googling for that error has not been helpful and suggests various things such as rebuilding gnuradio. Is there an easy fix (and if there is, could you add it to the Installing documentation please?)

I did try these commands but you can see what happened:

pi@ebay1:~/src/decode345-master/bin $ sudo pip install osmosdr
Looking in indexes: https://pypi.org/simple, https://www.piwheels.org/simple
Collecting osmosdr
Could not install packages due to an EnvironmentError: 404 Client Error: Not Found for url: https://pypi.org/simple/osmosdr/

pi@ebay1:~/src/decode345-master/bin $ sudo pip install osmosdr-gr
Looking in indexes: https://pypi.org/simple, https://www.piwheels.org/simple
Collecting osmosdr-gr
Could not install packages due to an EnvironmentError: 404 Client Error: Not Found for url: https://pypi.org/simple/osmosdr-gr/

(Also, complete newbie re mosquitto so if there is any setup needed there too, that isn't in your documentation, could you spell it out please? Haven't got that far yet.)

My experience so far has been with rtl_sdr, don't know much about gnuradio or python.

thanks,

Graham

solved it by trial and error, guessing at package names :-) ...

sudo apt-get install gr-osmosdr

Now it at least starts up (though haven't seen any data yet)

Getting a little farther now but still haven't seen anything that indicates it has received actual data from specific sensors. The requirement for MQTT is awkward - I think it is failing because my MQTT server (which was installed for another project, OwnTracks) requires a username and password. A module that just printed out sensor info as text would be really helpful as a confidence test in getting started. (Most of my other home automation stuff works by scraping the output of commands such as rtl_433 - I could get by quite happily doing the same with this.)
