Input.GetKey () does not work on mobile Bluetooth keyboard

Input.GetKey () does not work on mobile Bluetooth keyboard
Is there a solution or a detour method?

The latest version of Unity
I created a game that runs on Android and iOS.
We use “keyboard” to test the game. (Such as a cheat)

In Unity Editor, of course, keyboard input is good.
On a mobile device, I connect a Bluetooth keyboard.
On certain devices, the Bluetooth keyboard values are well entered.
I can not type on many other devices.
I typed the keyboard in Notepad and it was entered normally on all devices.
UGUI input field, Normally input is received.

I did not find something like this when I searched it.
thank you

there is no sulution and no support for this…
we ask the same question in 2011 and no response from Unity stuff or others until now…
it’s a shame… because Bluetooth Keyboard works in non Unity3d App’s on iOS !!!
On android it works very well but iOS nooooo way… :frowning:

I may have a solution for you with my asset iOS External Input:
