[teamclouday]

You've probably downloaded the latest v1.88 ImGui. I was using v1.78 while developing for this app.
Maybe try v1.78? Otherwise please drop all the .cpp files in ImGui root folder to the same place as imgui.cpp.

I'm not planning to update this app right now unless I have the motivation to learn Bluez 5 API 😂

[KaushikRathva]

can i help out somehow?

If you mean Bluez 5, Yes of course!
