Which model Orange Pi are you using.
Are you running Armbian?
In the early days of Outernet a friend of mine helped me install Outernet Linux version on a Orange pi running Armbian operating system.
It kind of worked but was early software,.
My advice would be, If the Outernet Linux software is still up to date try and follow the Linux instructions.
I have heard Outernet may have a Virtualbox image of Outernet Linux. if they do try that first, to get a feel for how the Linux Outernet works. (From Memory the Linux version is only a few pieces and not the full version of Library)
The CHIP is $9.00. Why not just buy one of those. And Flash it with the latest Outernet Image.
