Description apipa169 2018-01-24 23:52:30 UTC 
Hello,
i would like to control my Celestron 4se with kstars instead Skysafari over Celestron SkyPortal Wifi Modul.
I can connect if i use a cabel connection with Celestron Nexstar/GPS Driver but CANNOT if i try via wifi to my Celestron SkyPortal Wifi Modul to his IP Number. It works fine with Skysafari, so i know the problem is the Celestron Nextstar Driver from kstars/Ekos. I tried older and newer vesion of the Driver and kstars its the same problem. After just 5-10 seconds after it tries connecting, it stops with an Timeouterror!(See Logfile Output down below).  However if i try the EQMod Mount Driver kstars/ekos CAN connect to SkyPoral Wifi Modul, but i cant move the Telescope because its the wrong TelesopeDriver i suppose. But the fact that i can connect means that the Celestron Nexstar Driver could work, if it would be fixed, because how the EQMod Mount Driver successfully connects per IP over Wifi to the SkyPortal Wifi Modul. Also I tried a false IP with the EQMod Mount Driver and the connection failed, so the EQMod Mount Driver does successfully work with SkyPortal Wifi Modul(See Logfile down below).
Please update the Celestron Nexstar or GPS Driver so it can connect to Telescope via Celestron SkyPortal Wifi Modul!
Thank you very much for your work and kstars/ekos is a good software!

I use: raspberry 3pi, UbuntuMate 16.04, kstars/ekos 2.8.9, DSLR camera nikon5600 bulb via usb(&extern USB hub for power), Celestron 4se Telescope, Celestron StarSense Autoalign, Celestron SkyPortal Wifi Modul(at moment via cabel/usb because kstars doesn't connect to Skyportal)
Comment 2 Jasem Mutlaq 2018-01-25 05:05:20 UTC 
My initial guess is that perhaps the SkyPortal WiFi module does not recognize the "handshake" command used for cabled setups and so it times out. Try one thing, use telnet to connect to it from Ubuntu

telnet 192.175.11.36@2000

Once you're in, just type V and then press enter. If you responds, then it works fine. After that, try to type Kx and then press enter and see what response you get.
