Telescope-Pi is the name I gave to the Raspberry Pi 3 B+ I use to remotely control my telescope. This project contains an installer that will guide the user while downloading and configuring all the INDI drivers and software needed to control CCDs, DSLRs and telescope mounts. Moreover, a Bluetooth service is installed: if you are away from known Wi-Fi network, you can use its Android app to connect the board to another access point or even start the hotspot mode, ideal if you are, for instance, in a trip far from light pollution. The service will also start the Indi Web Manager (and the OpenFocuser server if installed) at startup, while the system service manager (systemd) will check if something suddenly crashed: if the server crashes, it is automatically restarted. No programming competencies are required to install the software because the installation scripts are completely automated and will even fix common Raspberry issues (e.g. Bluez and Rfcomm). When configured, just turn on the board (no mouse, keyboard or screen required), use the app to connect to a Wi-Fi AP and then remotely manage the telescope!
Usage and description
Behind the scenes, it’s an Indi Web Manager starter/stopper, network and power manager Bluetooth service for Raspberry Pi (Raspbian only, tested on 3 B+). Installers in the
install-kit folder will guide you through updating the system, installing, configuring and starting the server and its dependencies, just run them in the correct order. If you don’t need OpenFocuser, script 4 can be skipped without problems. You’ll be asked for a hostname for the server, a password for the hotspot mode and the network interface to control via Bluetooth. INDI and bluez will be downloaded/updated automatically and common troubles about Bluetooth in Raspbian will be fixed. Then some systemd services will be set up to correctly start the Bluetooth controller and indiserver.
I’m still working on a good Android app for Telescope-Pi. In the meanwhile, you can use a Bluetooth serial terminal app (in this way, it should work even with iPhones or desktop Bluetooth terminals, but I’ve never tested it in these ways): just connect to the board and all the available commands will be listed. Chose an option by sending a number and start controlling your Raspberry!
