Bluetooth communication using HID with my phone

Hardware
1

My problem is to be able to read through a serial barcode reader and then send the data to my tablet using bluetooth. I initially used the HC-05 module but this device does not implement HID and therefore I had to use one
bluetooth serial to test the project. My ultimate goal is for the tablet to recognize the arduino (via bluetooth) as an input device / keyboard. Wonder if it is possible to implement this functionality.

There are Arduino Bluetooth HID, you just have to search for that specifically:
BlueSMiRF HID

I have already checked the features of the device and they would actually solve my problems, however the device on https://www.sparkfun.com/ has been retired and in other sites is out of production. This is why I ask if there are other devices on the market that would solve my problem

Here is a link to a video which shows how to reflash the HC05 with the firmware from an RN42 which does support HID.

Turn your HC-05 into a HID Bluetooth device

thanks for your answer. I had also found this solution but I should test it because the fact of soldering on the hc-05 device does not convince me. I would be interested in having everything integrated already in one device. Reading on the internet I read that there are dispositvi but I would need help to buy the right one.
