I've had this up and running in a couple of days, then it seemed to run fine for a couple of weeks. Lately, the unit has been non-responsive. It gets a little hot. The WiFi doesn't show up. I'm about to ditch this whole project and re-purpose the parts for other projects, especially the RTL-SDR.
It would have been nice to have the CHIP or PI connect to a WiFi access point as a client with IP address that I can connect to. The current scheme of Outernet being an access point makes network configuration a pain. I have to turn off DNS and routing via Outernet WiFi so that it doesn't override my primary network connection.
I'm not keen on a custom RxOS that has to be flashed. I'd much rather stick with my existing Raspberry PI Debian or Ubuntu on a PC and just install the software packages needed to talk to the SDR to download the data and post-process it. That would be truer to the open source philosophy.
And why buy a CHIP when I can get a PI Zero for $5?
