The SHC also polls (but only to the main controller, not over WiFi) and pauses only 150ms between refresh cycles. To get an idea of the workload, the web server status page updates itself every 5 seconds, the OnStep app seems to update at least twice a second and SMP polls the RA and Dec coordinates every half second. I also tested both SMP and the app on my phone at the same time but obviously they both have to be using the same network mode (I only tested that combination in station mode). The OnStep app was running on my phone (Samsung S5) and SMP was running on my tablet (a cheapo RCA 10”… Stellarium mobile looks much better and is easier to use on the larger screen). My PC was running the Chrome browser connected to the web server status page over the station-mode network throughout the testing. OnESP was configured to enable both command channels (ports 99) as well as to enable both access-point networking (192.168.0.1) and station mode (192.168.100.124… an address in my home WiFi). For my testing, I used OnStep 3.8k on STM32, OnESP 1.11C and an SHC 1.5h on ESP32. I used as many simultaneous connections as I could over multiple simultaneous network types and it all worked flawlessly (with one exception I’ll describe later). Previously SMP’s OnStep interfacing only worked over Bluetooth but since the implementation of the more persistent command channel (port 9998) of the OnESP WiFi interface, which should be much more widely used than BT, I thought I’d give it another thorough testing. I’ll refer to Stellarium Mobile Plus as SMP in the rest of this post. The ‘Plus’ version (direct purchase or in-app upgrade) is the one that includes basic telescope control (as well as greatly expanded object databases, full sky images and hi-res planets). Stellarium Mobile is available for Android and Apple iOS. Stellarium mobile Sky Map is created by two of the original developers of Stellarium, the Desktop version of this famous astronomy and planetarium stars chart app.I posted a few months back about the availability of one of my favorite planetarium programs I’ve used for years on my observatory desktop, Stellarium, and its new ability to interface to OnStep from mobile devices. * GPS positioning, accelerometers control of the direction of view in the sky * 3D rendering of the major solar system planets and their satellites * accurate simulation of stars extinction, and atmosphere refraction * realistic landscape and atmosphere with sunrise, sunset and light pollution simulation * artificial satellites, including the International Space Station * asterisms and illustrations of the constellations for several sky cultures * a catalog of many nebulae and galaxies, with pictures for some of them * a catalog of over 600,000 stars displayed as a real time zoomable sky map This award-winning astronomy application is finally available on Android featuring: The sensor control will also enable you to identify a star in just a few seconds, just by pointing the phone at the sky! It shows a realistic and accurate night sky map, just like what you see with the naked eye, binoculars or a telescope. Stellarium Mobile Sky Map is a fully-featured planetarium for your phone.
