I am running your Oct 11 2017 version of Skysafari 5 pro on my Ipad air 2 , connecting to a Celestron Evo 9.25, (newer system with stronger WiFi)
Starsense HC, Ver 01.19.17280, BLD Oct 17 2017, Starsense Camera: Ver 01.02.113343, Motor Control MDL: Evolution Azm Ver : 7.13 Alt Ver: 7.13
It has been a few weeks since I used the software with the scope . Maybe before the Oct 11 update.
Last night I had no problem connecting to wifi on scope , ran Starsense Auto Align with no problem.
After a few minutes of GOTOs Skysafari would freeze up.
No blinking Circle on GOTO object, No jog response, no time or coordinate updates.
This would last for 10-15 seconds then SF pro would start responding, updateing normally again.
Everything would then work normally again for 10-15 minutes then freeze again.
Wait 10-15 seconds then back to normal.
Thanks for any help on this.
