Compatible bluetooth keyboard Rapoo E6300 and HTC Desire S?

Question

Android

Gave Rapoo E6300, tried to connect it to HTC Desire S, Nokia N800, Ubuntu (via bluetooth adapter), Mac Book Pro. Earned only with the latter, where it is completely useless. The N800 managed to print a few characters, after which it stopped responding to it.
Is there anyone who understands Bluetooth HID - what can it be that just supporting the underlying protocol is not enough for normal operation?
Pairing with HTC goes well: you type the code on the phone, then it from the keyboard and Enter, after that the keyboard appears in the list of devices with the status “Connected. Disabled" and no longer manifests itself. I tried to install BlueImput, but that didn’t help either: it sees the keyboard, but when I try to connect, it says: “Error: Failed to open a connection to Bluetoth Keyboard”. I'm not talking about Cyrillic printing, the phone would somehow react to it.
On the manufacturer's website, all the answers are from the category of "la-la-la, check if the battery is inserted." On the net I found the following links on the topic:

I don't plan to root the phone, especially while it's under warranty, for the sake of the keyboard. The main question for connoisseurs of the topic is what is so special about connecting a keyboard that such dances with a tambourine are required? Well, maybe someone found a way to make them friends?

Answer 1

with galaxy s 2 the flight is normal.
but you need to do this on it: select the device "Bluetooth keyboard" (under it there will be an inscription "Authorized"), select the item to break the connection,
select the item "Bluetooth keyboard" again to connect.
A message appears that you need to enter such and such a number, you enter the number on the keyboard, it is connected.
You don't need to enter anything on the phone.
My colleague tried to connect to the keyboard through his galaxy ace, he did not succeed.
his phone gave out the message “enter the code” and the input field (that is, the code had to be from the phone). You don't need to enter any code on galaxy 2, you only need to enter it on the clave itself.
By the way, no one knows how to switch the layout on it?
