Android Question Server less BLE Mouse

[GoodGuyOnWeb]

How to convert phone to BLE mouse (HID) without installing any app in device being controlled? I have looked into Erel's Controlling Desktop code but it requires B4J app to be installed in laptop.
Eg App for sever less BLE Mouse available in Play Store:

It is impossible.

Thanks for the reply, Erel , but the app that I linked to in my OP does pair with my laptop and works without any additional app on the laptop.
'Bluetooth Keyboard & Mouse' app available in Play Store:
https://play.google.com/store/apps/details?id=io.appground.blek&hl=en&gl=US
If you have time, please do check it out and perhaps suggest how they are able to do it ?
Thanks

Like @GoodGuyOnWeb i have tried the "Bluetooth keyboard and mouse" App. It works like a charm on a Samsung A23 / Android 13 and connect the phone on Win10 as HID (If you have a previous non HID connexion from the device to your PC, forget first this pairing). Maybe is an enlightenment in the link below. If i'have got some time, i will explore it.

Interesting. Does this app work with BLE or classic Bluetooth?

I wasn't familiar with the BLE HID protocol. This will require implementing the specific protocol. You will need to modify BLE2Peripheral library for this. Not simple.

Here is source code ( Kotlin ) of similar app using classic Bluetooth version : https://github.com/LiangLuDev/HidPeripheral
Hope it can be converted to b4x code.

Will be using completely different approach (Not Phone) ! Xiao ESP32C3 with BLE Mouse Library
