Cannot send keyboard signals when the keycode is over 128

I wanna make a bluetooth keyboard with a Bluno Nano.
It works with any key codes but it doesn't if the key code is highter than 127.
I can see messages like "AT+KEY=224" on the serial monitor.
But that doesn't do anything if I connect to the PC with bluetooth.
I have set the AT+FSM to HID mode, and other keys are work correctly.
So, how can I send the key signal over 128?
What can I do?
