I'm back to exploring the idea of using one of the Android apps that will re-route a Bluetooth connection to a TCP port on the phone/tablet, which then could be connected to as "wifi" from the smart device (really using Bluetooth underneath though).
The hitch with that, is getting the smart device to send the required UDP broadcasts that advertise the connection.
It.. works!!! With both SkyPortal and SkySafari!
1. This is "mount Bluetooth" from the AUX bus, the same as provided by either this project or by the original WiFi+Bt+GPS project.
2. The Android BT/USB/TCP Bridge Pro app is used to connect to the Bluetooth, and make it appear as if it was a WiFi server connection at port 2000 on my smartphone.
3. A Termux app session on my smartphone runs the Linux socat command in a loop at 2-second intervals, with suitable parameters to generate the periodic UDP broadcast advertisements that SkyPortal and SkySafari both listen for.
4. SkyPortal and SkySafari both connect to and control the mount successfully through what they think is a "wifi" connection, but really over Bluetooth to the HomeBrew adapter.
5. All functionality is there, including alignments, calibration, mount settings, etc..
Now I just have to ponder how to lessen the wizardry requirements so that others can also get it working!
