AFTERPAD

Interesting! So that means that Steelseries has a working controller (Nimbus) and one that sports the disconnecting issue (Stratus). Maybe we should send them an e-mail regarding this: maybe they can at least tell us if they have different bt modules or something.

Hey Folks,

same Problem here. iPad Pro 9,7 128GB and iPad Pro 12,9 128GB.

I filed a bug at Apple (28649216):

Summary:
After a few minutes of gameplay - sometimes 5, sometimes 20 - two MFi Gamepads (Steelseries Stratus and Madcatz C.T.R.L.i.) both stop accepting inputs. They are still connected to the iPad Pro (9.7) but don't accept input in any app. The companion-app of the CTRLi does not show a connected device, while the settings app shows the controller as being connected. Turning the controllers off and on again usually works once: but after 5 to 20 minutes it stops recognizing input again; and after that only a reboot of the iPad re-enables the connection between the devices. This is also happening on the 12,9" iPad Pro of my wife and there are various users on afterpad.com that have the same issue.

Addition: I forgot the device under settings > bluetooth and re-paired it (problem persists), I reset the controllers (problem persists), I reset my network settings (problem persists), reset the iPad and recovered from an iCloud Backup (problem persists) and even set up my iPad as a new device (problem persists). Help.

Addition 2: I don't have any other devices connected to the iPad at a time. Only one of the controllers is paired with the iPad.
