Hi, before I realised you could transfer the GPS location from your Ipad to SM, I bought a GPS receiver. I have not managed to get this work, Not sure if its the device or SM, followed instructions, but no joy. Now I want to go back to using the SM app to sync the GPS data for SM. I'm not sure what the settings should be in Ekos and Kstars to do that, as there doesn't seem to be an option for that. its only Kstars, mount or GPS device.
Not sure if this will work but you could try the GPS2IP app. I use it on my iPhone and that works. Never tried it on my iPad though. Search the forum for GPS2IP for instructions on how to set this up.
Which GPS receiver did you get? Is it a USB or dongle? I recently created a StellarMate image. I use a U-Blox 7 USB GPS. Both types take a dedicated ttyACM port.
