Hello Jenkisan,
Sorry for not replying any sooner. I must have missed the notification of your post.
I don’t have any IOS devices to test with, and I’m totally unfamiliar with the IOS app landscape, so I couldn’t tell you.
Basically, if an app supports online tracking via HTTP, it should be viable and not even very difficult to add support for it to Trackserver. If you have any suggestions, please let me know so I can have a look.
As for the standard protocols you mention: as far as I know, these are not HTTP-based protocols, so Trackserver, being a WordPress plugin, cannot support these by nature. If you know of any protocols that ARE HTTP based and not supported by Trackserver (GpsGate would be a nice example), feel free to let me know.
Best regards,
Martijn.
