Raspberry Pi 3 Pip Install Editable Mode Observations

[kb1lqc]

Summary

I'm installing faraday software on a Raspberry Pi 3 from github sources in editable mode i.e. pip install -e .. This issue ticket will collect some of my observations and nuances as we explore creating base stations with Faraday.

Problem Explanation

PRetty much all stated in the summary.

Environment

Software

• Faraday-Software, starting with kb1lqc@83ae953 but also using Master at times.
• Raspbian OS

Hardware

-Faraday Rev D1

• Raspberry PI Model 3

Supporting Information

• faraday-proxy and similar commands were NOT installed even when no errors were observed with a pip install -e . command. I had to run the command with sudo to get it to actually install.
• faraday-proxy --init-config results in error:

[kb1lqc]

faraday-proxy --init-config failed because I was not in the project root directory. I remember this being an issue we've known about with editable installs. You cannot run the software outside root.

• Needed to run sudo faraday-proxy --start with a properly configured Proxy to get /dev/ttyUSB0 to be connected to

• Since I'm using my latest Update APRS Application to Handle Network Errors Gracefully #119 'issue119' branch I have not yet (TODO) added aprslib to the requirements file for python pip.

Interesting, when starting faraday-aprs connection was refuse to telemetry...

[kb1lqc]

Solved the /stations telemetry connection issue by killing the telemetry program with sudo kill -9 <pid> and then starting it up in root with sudo faraday-telemetry --start.

However I get another error now.

[kb1lqc]

OK it looks like the SQlite database is locked... therefore no data is sent from telemetry and the aprs program will timeout:

Hmm this could be a big problem for Raspberry Pi. Googling suggests it could be a speed issue and we'd need to move to mysql or similar. I'm not sure, this seems ridiculous that it wouldn't work...

Just noticed that I needed to install with --force on latest Raspbian!

Also noting that on the RPI using a fast SD card makes all the difference. Just started using a level 10 SD card and the RPI is snappy compared to my old level 4 card!
