Thank you for the reply.
Someone once told me drain the swamp, then the crocodiles go away.
My background is in Sun Unix. About 20 years ago I took a contract with a german company to write an installation manual for a telecoms management system. The company were having difficulty getting it installed correctly in the field.
I struggled with writing the manual, lots of "if you have this card.... then..." . After I had been working for a few months it became clear that changes of technology - that is new computer models etc would make this document a maintenance nightmare
I decided, while nobody was watching, to ignore what I was told to do and just write a Perl script to do the whole thing. Four weeks later the script was written, tested and the old documentation set was abandoned.
This script was then added to the Sun Jumpstart CD and the install time came down from 2 days to 2 hours.
So here is my suggestion.
Your software installation doc should be cut down to a few lines.
Pre-requisite a raspberry pi with a ethernet connector plugged into your router ie not a zero or zero W
1 download jessie-lite from rasperry pi.com
2 burn a microsd card
3 plug in card into ethernet pi and boot
4 ssh to pi and
5 apt-get update
6 apt-get install erle
7 If you are using a Pi zero, shutdown ethernet pi and move card to target pi zero
8 ssh in and run create-hotspot.sh -y to re-config the wifi connection etc
All you have to do now is turn all the MAV ROS stuff plus Arducopter into Raspberry Pi package and get it on the server.
The create-hotspot.sh script should have 2 options -y creates the hotspot, -n restore the normal wifi client config.
If Erle release an upgrade, then the user just runs create-hotspot -n, takes the card from the zero and puts it in an ethernet pi ( if reqd ) and runs apt-get install erle to upgrade the Erle stuff.
I would also suggest that you think about closing your forum ( or at least the software section ) and instead create a topic on the Raspberry Pi forum.
Using the Raspberry Pi forum will expose your product to a far wider audience,
I came across the pxfmini quite by chance.
I regularly read the UK based online Tech news site - theregister.co.uk, they have been supporting the LOHAN project for some years, this project is about getting close to Space using a helium weather balloon and Pi based tech.
A while back I read that Andrew Tridgell (Samba daddy) had got involved, this lead me to youtube talk by Tridge about Ardupilot - he mentioned the Erlebrain...
If you use the Pi forum, you will increase the exposure of your products by a factor of thousnads, and I would expect you to see sales of Erle products to jump by a similar amount. You will also get a lot of Pi gurus on the case helping solve all sorts of Pi related problems.
