Help plase with connect keyboard to arduino

Using Arduino Programming Questions
1

First of all, I hope for your help, because I really need to connect this keyboard very much.
Secondly, I bought an Arduino Uno, a Lenardo and a Mini, and I tried all of this and the keyboard did not work for me. when i use sketch hidkb.io Nothing happens when i use sketch hid multi kb and mouse see word start in serial monitor I see word start When I press any button on the keyboard, it says "start"
my keyboard Is drevo blademaster with arm cortex 32bit mcu

Hi, welcome to the forum.

Are you using a smart phone that translates some words to links ? It is very confusing.
When you have access to a desktop computer, then you might try to modify your post.

Which keyboard to you have ? A "PRO" or a "TE" ?
This the the BladeMaster TE: https://www.drevo.net/product/keyboard/blademaster-te

What do you want to do with that keyboard ?
Does the keyboard work when you connect it to a computer ? What do you want to do with a Arduino ?

When you use a library or a sketch, please give a link to it or show the sketch.

3

It is an easy way to connect arduino to keyboard by simple process of programming.

4

@williamander please prove that you are a human being and are interested in Arduino.

thanks for reply
1- iam use drevo blademaster te
2-i want to convert this wired to BT
3-yes workin on my pc
4-i want to connect keyboard to arduino to use BT
5-iam use library usb host shield v 2.0

6

Is there a dongle/converter for that ?

The normal Bluetooth modules are only for Serial communication. There are also Bluetooth modules that are more versatile.
I have never looked into this, so if you search for a solution then you find as much as I can find.

I found this: https://hackaday.com/2016/09/04/convert-any-usb-keyboard-to-bluetooth/

7

I want to convert this keyboard from wire to bluetooth
I applied all the steps that you mentioned in the topic you shared with me, but the keyboard did not work
All I need from you is one thing
I want to play the keyboard on a USB host shield with arduino
But when I use the library, the keyboard does not work and gives the results that I mentioned in the first topic

8

What model of "USB Host Shield" do you have?

Which library are you using?
V1: GitHub - felis/USB_Host_Shield: Libraries and code for Circuits@Home Arduino USB Host Shield
V2: GitHub - felis/USB_Host_Shield_2.0: Revision 2.0 of USB Host Library for Arduino.
Some other library?

Is this the sketch you are running?

9

yes I have usb host shield v2.0
iam use sketch USBHIDMultimediaKbd.io

10

Did you try a Google search for:
usb host shield 2.0 "osc did not start"

It's saying that your USB Host Shield is not getting power from the Arduino UNO. Is there some jumper you are supposed to use to power up the board?

11

no
usb host shield power up and power up my keyboard and i making jumper power 5v and try with external power

12

iam do not know how to decode the hex dumps
i want any help to modify this sketch to workin without hex

#include <hidcomposite.h>
